Reddish brown spots on eponychium
Hi all. Sometime in 2009, I noticed my toes,fingers and nails turn bluish/purplish when I got cold, then it started happening even when it wasn't cold. I went to the local clinic and was put under ECG and it picked up Artrial Fibrillation(don't know what it meant). Was then reffered to the hospital where i did another ECG, X-Ray and several blood tests but nothing came out at that time. The doctor who did all this was convinced it had to do with my heart but the results showed everything was ok. Then he refered me to a cardiologist, where i was booked for the 24hr ECG, which also didn't show a problem. Now 2yrs later my fingers and toes still change colour everyday alternating between bluish/purplish and pale. And for sometime, my eponychium has had reddish brown spots that I thought would disappear but they won't. I have these spots on 5fingers, 1 on left hand and 4 on right hand.My right index finger is the most affected, with spots so close together it almost looks like a line. What could be wrong with me? Help please.
