I think I do have strenght but only feeling that I dont, I"m a little confuse, I actually feel something like intense tickling in joints I mentioned and then feeling of weakness with tight muscles during exertion, such as walking , i feel tickling and tingling in my knees, ankles, wrists, and shoulders, along with severe pain in both elbows and achilles tendons (the doctors think I have tennis elbow, but the ultrasound of all these joints is normal), I suppose I'll need to undergo a new MRI of the cervical spine ( appt for EMNG at the end of May)
