Hi, I am a 40 year old female 5'9" and 156lbs. I eat very healthy and workout regularly. I have been suffering form extreme fatigue, aching bones and muscles, inability to concentrate, hair loss, weight gain, etc... I went to the dr to get blood work, she (the dr) thought it would have been thyroid, but everything came back normal except, my platelets were 106, which is low. I also have a lump on the right side of my throat that has been there for a couple of months. Any idea what could be causing these symptoms? My doctor doesn't seem to concerned, but I am tired of not feeling well.
