muscle spasm
"So the doctor decided to prescribe me this when I had pneumonia. Then moved me up dosage and then told me to stop taking it. I ended up with horrible electric shock symptoms permanent. I tried going back on it and weaning myself off. I have had every test known to man and the doctor finally admitted to it being from the medicine. As I am having these electric shock sensations it makes my muscle super sore and is horrible to live with this. So to keep the pain and shocks down I am 29 years old and am taking 4 Tramadol a day. I wanted to warn people that this is a real problem that I wouldn't wish on my worst enemy."
