Hi Everyone,


Last December, I woke up and discovered my left middle finger was misshapen and the top knuckle bent down. My local rheumatologist doctor diagnosed it as Swan Neck Finger - said the other ones may do the same over time. Yesterday I noticed my right index finger is bent and looks as if the top and bottom are veering off in opposite directions. Also troubling is my thumbnail on my right hand - there is a perfectly vertical, raised ridge line going the entire length of the fingernail. I went for my weekly B-12 shot this morning and my primary doctor said it looks like the ridge has a darkened edge and could mean vitamin deficiency. That makes sense because I am deficient in B-12 and Vitamin D. I notice every one of my fingernails looks lined and a couple look like they could be forming a ridge like my thumb nail. Is this another way of systemic sclerosis looming its ugly head at me? My nails have always been brittle, since I was little.

I'd not heard of swan neck finger before. I have sclerodactyly hands myself so can sympathise with having hands that look far from normal and have impaired function. Mine is a direct result of scleroderma.


We have information about fingernail changes in scleroderma that may be of interest to you.


Take care and keep posting.

I have swan neck deformity in two of my fingers. My rheumatologist told me it's a normal result of aging and not related to scleroderma. Whether or not that's true, I agree it's not pretty but at least it hasn't affected my manual dexterity.


Most of my fingernails (and probably my toenails as well, but I haven't examined them as closely) are a mess (with ridges, cracks, valleys, odd curvature, etc.). They get worse in the winter, which doesn't make a lot of sense. But, with this disease, what does?
