Hair Loss and MS

I'm still not sure if my hair loss is due to MS or is my thyroid medicine still screwed up.  I have read on some sites that the hair loss is to do with MS and others adamantly say no. Well, for right now, I will have to wait and see because it is too expensive to go to the doctor's for more blood work.  Counting the days till July 1, 2011 for Medicare to kick in, as long as the government doesn't go broke in the meantime.  If you have the same problem with hair loss, please leave me a comment as I'm really frustrated.
