I found this web site trying to find information for my husband. His right arm began twitching in July. He tried massage, heating pad, and lessening weight training, but it did not let up, so he made an appointment to his primary care dr. The dr. told him it was probably an overused muscle and gave him an anti-inflamatory and told him to return in 2 weeks if it did not stop. Let me describe his symptoms: twitching in his right arm from his tricep to his elbow 24/7! After taking the medicine, and it not helping, he returned to his doctor. By this time he and I were concerned, because I had to him that he might have symptoms of multiple sclerosis, but it generally affects the legs, but has been known to affect the arms first in some individuals. Anyway, after this visit he told his doctor his concern and the dr. referred him to an neurologist. After waiting a month to see him, the neurologist did looked at him and did an exam and told him that he did not have a neurological disorder and to not think about it! He said that he continues to have the twitch that he could come back in a month and have a nerve test, but it is pretty painful. He reassured him that he had 25 years of experience and that he was a very healthy man. Mean while his arm still twitches and the day September 21. Does anyone have and suggestions? I forgot to mention the twitch is pretty strong you can see it and it feels like a pulse but not a consistent rhythm.
