I don't know what is going on, but I noticed the other day that most of the hair on my arms and legs is gone. Not that I have ever had a lot of hair on arms or legs, but it is scaring me that it has disappeared. I used to shave my legs more often, and now it seems like I don't need to anymore. I have very long, thick hair on my head, and I haven't noticed any hair loss there, just on arms and legs. I am currently pregnant, so I don't know if that has anything to do with it or not. I read a bit online, and saw this can be caused by everything from hormonal changes to thyroid conditions to other things much worse. I have never had any trouble with my thyroid, but thyroid conditions do run in my family. Could any of this be FM related? I am really worried about this, and definitely will ask my Dr at my next appt.
