I was diagnosed with Thoracic outlet syndrome about 2 months ago, my symptoms have always been pain in neck and shoulders with weakness in forearms and arms feeling heavy especially when doing any activity with arms. Some numbness in fingers occasionally. Here recently I have been having extremely aggravating muscle twitches in my thigh muscle and my upper arm muscle only on the right side, none at all in my left side. So I was wondering if anyone else has had this issue/symptom, because it is driving me nuts?
