Hi Dew,
I found out nearly the same way as an after thought and being sent to a rheumatologist. I also thought mine was some sort of female menopausal thing. I have had this for about 5 years also. It's no fun and family just doesn't understand. I am having trouble with going to work because of the constant fatigue! Just can't sleep and headaches are a real problem. Also have been diagnosed with mild cognitive disfunction. Anyone else? I am new to this site so appreciate any advice. Nice to know I'm not alone. Hang in there.
