Rheumatoid Arthritis Support Group
Rheumatoid arthritis is a chronic, inflammatory, multisystem, autoimmune disorder. It is a disabling and painful condition which can lead to substantial loss of mobility due to pain and joint destruction. The disease is also systemic in that it often also affects many extra-articular tissues throughout the body including the skin, blood vessels, heart, lungs, and...

longterm use of mtxt can make skin thin too.
who knows what exactly might be the reason for this, but sounds scary.
I was told by him it is caused by prednisone. I couldnt see what you take on your profile page. My rheumy nurse also says methotrexate can cause it.
(At this point I feel inclined to quip that kale will cure it.... ) I suspect any number of drugs might cause it and mine comes and goes.
It isnt serious (I am told) but is a reminder that the disease is bad and the drugs come with their added issues.
Doctor's prescribe it - it helps, but AFTER we take it, we find out what it does specifically to our own body.
I was prescribed 5mg a day and knew it messed with glucose, causing many to become diabetic. (I doubt on 5mg, but who knows the magic number?)
Instead, I only took 1/4 of that. I hurt for a long time til methotrexate kicked in though. It's such a tradeoff. I hope you can slowly reduce your prednisone. Dropping by 5mg might be too harsh. I wish you luck!
