I may have a few things going on. For the past six months I have been developing brown patches on my skin. On my forehead they look like what is called the pregnancy mask. There are also on my back primarily in a line down my spine. I was thinking a form of ezcema..? About a month ago I had several days where my skin down my left hand was painful. It was weird since it was not muscular. My hand was achy, but if I touched my hand it felt like someone was slapping me very hard. I was thinking it may be due to a vitamin deficiency (although I could not figure out how that was possible!). I started taking a multivitamin and it seemed to go away. I now have bruising which has shown up on my thigh. I did not have any injury. It is spotted and 5inches by 3inches. Any ideas?
