I am 27 years old female. I am suffering from juvenile rheumatoid arthritis. Both the thumbs of my hand have developed fungal nail infection. The nails of thumbs are growing yellow and brittle and like a mound which cannot be cut by nail clippers. The nail removes automatically after a month or 2 but regrows the same. I have consulted local doctor and he said it happens in JRA due to irregular flow of blood. I am a working woman and work with computers all day. None other finger nails have the problem
