      It is not uncommon to read about digital clubbing (finger nail and toe clubbing) as a symptom of pulmonary fibrosis (PF) when conducting an online search into symptoms or indicators of this disease. It is something I watch for on the regular as a patient living with idiopathic pulmonary fibrosis (IPF). Thankfully, it is not something I have noticed yet, but many of the people I know and love living with this disease do have this symptom. To the members of our forum community:

      Have you experienced digital clubbing as a result of your PF diagnosis?

      Is it painful?

      Does it make fine motor tasks more difficult to complete?

      Do you have any tips to managing digital clubbing?

      Please feel free to read more about digital clubbing from a piece that was published on Pulmonary Fibrosis News in 2016 by our very own Michael Nace.


      Digital Clubbing in Pulmonary Fibrosis


      Clubbing of the fingertips and toes is a symptom seen in pulmonary fibrosis (PF) and other heart and lung diseases that reduce the amount of oxygen in the blood. The symptom is evident when fingertips are enlarged and rounded in contrast to the rest of the finger. A finger with clubbing at the tips resembles a drumstick-like shape.

      The exact cause of clubbing in diseases such as PF is not fully understood, but the unusual symptom has been identified as a marker of advanced-stage disease and should be reported to a physician immediately. The American Thoracic Society notes that digital clubbing (clubbing of the fingers) may be associated with reduced survival for people with idiopathic pulmonary fibrosis (IPF), but additional studies are needed to confirm that suggestion.


      What causes digital clubbing in pulmonary fibrosis?


      Clubbing occurs as a result of increased fluid pooled at the ends of soft tissue in the fingers. While the exact reason for this is unknown, clubbing is directly associated with a reduced amount of oxygen in the blood.

      The process of clubbing has been observed to occur in stages. It begins with the stage known as “Scarmouth’s sign” — softening nail beds and shiny skin around the nail. Some references describe the nail as seeming to float above the nail bed. The fingertips then begin to round and enlarge into the drumstick-like appearance. The nail will begin to curve along with the shape of the fingertip. The fingertips may feel warm and appear red.

      Digital clubbing can also occur in the toes.


      Treatments for clubbing

      Clubbing is associated with reduced oxygen levels in the blood. In IPF, clubbing is usually treated in conjunction with related symptoms including shortness of breath and breathing complications. Therapeutic approaches include oxygen therapy, which increases the concentration of pure oxygen in the lungs and allows for increased absorption.

      I had not noticed it until my doctor pointed it out during our last appointment. As of today it hasn’t bothered me.  The shape of my fingernails are changing but I have not experienced pain.

      Hi Gil,

      Thanks for getting in touch and as always, it is so nice to hear from you!

      The digital clubbing isn’t something I really noticed either until I asked my doctor why he was examining my finger nails and hands. He explained the concept of clubbing to me but not very thoroughly so I was still a bit confused until I read the column I posted here. Unfortunately I think I can start to see this happening in my hands.

      Glad it hasn’t bothered you, despite your doctors noticing it and I’m really glad you don’t have any pain with it! I hope you’re enjoying your time with family on the coast 🙂

      I have the clubbing of the fingers, but my main problem is being so weak so fast. I am in year 6 i think. I live in Fl. and visiting my grandchildren in Alabama. I just hope that I can make it back to Fl. Jan.2, I don’t want to be in any hospital or have the children see failing. I will have to change doctors as he keeps calling it COPD and has not been any help.Not that there is anything he can do. Bob Foss [email protected]

      Charlene, I definitely have clubbing in hand and toe nails. They are rounding in both directions, parallel and perpendicular to the finger or toe. I think the nails are Aldo more shiny. There is no pain.

      Have a wonderful Christmas and a better next year,


    • #26607

      Hello my friend Rene!

      I was thinking of you today and wondering what it would be like to enjoy Christmas in a warm and sandy climate. I’m jealous!

      Sorry to hear of the clubbing in your nails, I hope they aren’t uncomfortable? Glad to hear no pain! I think of you lots and hope you have a wonderful Christmas and all the best in 2021. May it reveal great things for all of us!

      Take care,

      My husband does have digital clubbing of his fingers.  That was the first thing his Pulmonologist noticed in early 2014.  It does seem to cause any discomfort but maybe he has had it so long that he no longer notices it?  In any event, he says that he can’t remember (nor I) when he didn’t have the clubbing

      • #28326

        When does clubbing start? I mean I am sure everyone is different but would you or could you notice it right away?

        • #28337


          Hi Tammy –

          Really good question! Similar to the progression of the disease; clubbing really seems specific to each person and whether they experience it. I have really deep nail beds normally and it feels like the “chubby” or clubbing around my fingers isn’t specific to the disease as I’ve had it for years. I am chronically under-oxygenated but don’t (I don’t think anyways?) experience clubbing.

          Has anyone else noticed and at one point throughout the disease, ie how long after you were diagnosed?

      Hi Charlene, I don’t think I have club fingers, but I do have changing nails which are getting bigger, more rounded and shiny. This symptom is not at all painful.

      About Christmas in a tropical island…of course no white Christmas unless you mean our beaches with white sand, haha. We give the presents to our kids on December 5 with the celebration of Sinterklaas who is a bishop from Spain who puts presents in the shoes of kids which they leave outside. The kids put carrots in the shoes so Sinterklaas’ horses have something to eat.  Of course next day the carrots have disappeared which is proof that Sinterklaas is real. It’s a long history. We did not have SantaClaus, but that is also changing due to foreign influences.

      Christmas is not so much for presents but much more a religious celebration of Christ’s birth, going to church usually on Christmas Eve and Christmas Day sometimes sharing a meal with family or friends.

      Sinterklaas is a very wise bishop so next year I will ask him about IPF and the effect of too much oxygen and club fingers.

      Love this reply @renehakkenberg, it made me smile… thanks for starting my day off this way! 🙂

      I’d much rather your version of “white Christmas” than ours, because yours involves a beach and Canada’s is cold. That said, it was the most picturesque, classic Canadian Christmas we’ve had in years this year. The snow began falling Christmas Eve and didn’t stop until Dec 26th. If you didn’t have to drive anywhere, it was really beautiful and my dog sure loved it.

      Thanks for sharing the story of Sinterklaas too! Such neat traditions all over the world.
      Wishing you the very best for the new year my friend!

      Hi Charlene,

      No clubbing as of yet but I do have a couple curved in toenails similar to ingrown caused by diabetes. That got a little worse during the past four months…

      Stay well,


    • #26786

      You too, @steve-dragoo … stay well! I’m so glad you’re on the mend a little more than the last time we connected.
      Take good care my friend,

      13 years with IPF. Very slow progression. No treatments although we tried Esbriet and Ofev briefly in 2016. Side effects forced the end of treatments.

      No clubbing on hands but feet have weird shapes on toenails. Had surgery by a podiatrist about the time that my IPF was discovered. My big toes had ingrown nails. Podiatrist cut back the side edge of nails and killed nerves beneath to prevent regrowth. This was done independent of the IPF diagnosis and no one connected the two. Now, I wonder if that condition was connected to IPF.

      Except for the unmistakable honeycomb formation in both lobes of my lungs and some shortness of breath one would wonder whether I actually have IPF.

      Hi Ron,

      Thanks for writing and sharing your experience with us. Sorry to hear the IPF treatment side effects forced the end of treatments, they are both difficult drugs to adjust to, I agree! That said, glad to hear your IPF is very slow progressing, I hope it remains that way for a very long time.

      Interesting about the toe nails too, a few people have mentioned something similar so I would imagine they are related. I don’t have the classic clubbing yet that is described with many IPF patients, but I know lots do. Does anyone else have clubbing or issues with your toe nails and IPF? I’d be curious to hear.


      Thanks again for sharing Ron.

      • #28445

        May i ask how they seen the honeycomb feature? What test revealed it?

      Yes, have definitely noticed the clubbing in my husband’s toes. Gradual changes over the progression of the disease. Diagnosed in 2019. Is not painful.

      I don’t have clubbing in my fingers (I don’t think), but for years a couple of my nails have grown weird, turning down at the ends in the middle.  I have wondered if this is clubbing.  Also, I thought I had an ingrown toenail on my big toe, but its not.  It did hurt.  I suppose it could be clubbing.

      • #28400

        Hi @paulette-daniels, It sounds like minor clubbing in your fingers. My mom’s nails turned down at the ends first, and kind of widened out, then the slope gradually seemed to fill in toward the cuticle until they had the typical rounded appearance of clubbed fingers (toes too). She kept her nails pretty short once they started clubbing. But within a few months after her transplant, the clubbing was reversed! Amazing stuff.

    • #28395

      Hello friends,   I dont really notice my fingers clubbing but my fingernails are. They are flatter and wider and curve over end of finger tips. Nails on both great toes have developed thicker nails and are growing very strange. I feel like I need to file or dreamed off the extra nail, but will consult podiatrist. All of this started when I started Ofev , a drug that has bad side effects, but works. I hate the loose stools , nausea and fatigue, but will stay on it until my lung transplant soon…

    • #28668

      This is almost identical to what my husband’s fingers look like.
