I have been tired off and on for about 3 years now. The fatigue would be accompanied by achy knees and wrists and elbows and low back... Flu like symtoms. I was also experiencing tingling in both feet and a vibration feeling....like I just rode a quad for an hour and my feet still felt like I was on the bike. After relapsing several times in a year, I went to the doctor. After several tests for Lupus, Lyme, Rhumatoid Arthritis, etc. they told me that they could not find anything wrong. My doc put me on a drug called Plaquenil to treat arthritis like symptoms. I did not have a relapse for almost 3 months.....until last week. All of the same symptoms came back but this time I felt muscle twitching in my lower legs up to my knee. This is very scary to me considering that there are lots of neuroligical diseases that present this symptom. Does anyone have these symptoms and do you have any recommendations on getting this diagnosed?
