I was doing my hair and then looked down at my hands and my right palm was bright pink! It looked like I had stained it or rubbed it in pink chalk. At first I thought maybe I got something on myself but I hadn't touched anything! I even tried to wash it off with soap and rubbed it on a white cloth but it didn't come off. Finally I figured out it was me! After a while it went away on its own. But my arm ached a bit. What could have caused this!?! Has anyone had this experience before? My last labs had a high sed and crp - indicating inflammation but my RF was negative. Could this be RA anyway?
