Hello, I have been having a horrible time of it for the last four months with symptoms that that go on 24/7. I have been tossed around from doctor to doctor without any relief and I am exhausted and confused. My symptoms came on suddenly, I have constant muscle fatigue, spasms/twitching/burning, loss of appetite/weight loss. Even my stomach muscles are vibrating. My knees on the sides ache and turn red when I stand too long or walk. My muscles are sore from my eyeballs to my feet. I have had an EMG which was normal. My blood tests are normal including thyroid. How can you tell if this is nerve pain or muscle problems? Do pain meds work better thsn muscle relaxants? I do not know where to turn or who to believe. Every doctor I have seen has a theory from yeast overgrowth to mystery illness.
