My friend's husband has severe fibromyalgia and diagnosed for many years. He's down to 120lbs. Has been in and out of the hospital for many problems. He is taking highly addictive narcotics prescribed by a doctor as well as Xanax. Doesn't sleep properly maybe a few hours during the day. Today he is almost unable to walk without a walker, has constant intestinal problems daily and now his face is swollen and his testicles are swollen to size of oranges. She has called the doctor and he said to admit him Monday. I say he needs to go now. Do you have any idea what is causing the swelling possibly?
