Before 3 years it stated to drain pus from toes but we were not serious about it as it was getting well for 2 months and then again starting. Last year, it became serious and didn't get well on home treatment. So we did a operation and removed both nail and did as prescribed by docter. We wrap gauge everyday with bitadine solution. After 3-4 months new nails grew and it was all good. But now it again has started. We can't understand why it is happening again after surgery.

I have wrist and thumb joint pain. I could not lift small weights sometimes. The pain is not severe but I could feel it even while brushing. Most of the times I feel very less pain but the pain is continuous. I don't what to do.

Should I consultant a orthopedic or general surgeon or some other doc?
