OK....this will sound bizarre, but there seem to be a lot of strange side effects with OHS. I know that fingernails can sometimes be used to diagnosis medical conditions. After my surgery I noticed that the middle fingernail on my right hand has a very noticeable vertical depression (sort of opposite of a ridge) near the right side. I know I did not have this pre-surgery; only noticed it about two weeks after surgery when I was idly rubbing another finger over it. No pain, no discoloration. Anyone else notice anything like this???
