question: My boyfriend is 32 and started going through Xanax with drawls on Tuesday. He was severe muscle spasms for about 7 hours consistently they have slowed down but are still occurring. Yesterday I noticed his right shoulder arm and hand were swollen the swelling goes down into his back as well. He is having intense pain in the shoulder as well. When he sat up I noticed that his right leg and foot started swelling as well the blood vessels in his foot looked like he had a tourniquet around his leg
