Male 52 Yrs. old with Pain in Back and right shoulder and arm.?

Male 52 Yrs. old with pain in lower back and right shoulder and arm. Have had pain for 1 month and am taking lots of Tylenol. Even high doses of Sodium Naproxen that the Doctor prescribed would not kill the pain. The Tylenol works for a short time than wears off, but seems to work better than the Sodium Naproxen. Man was in hospital for emergency rectal abcess, and had to have two incisions made on rectum to drain the infection. Man received an antibiotic called Keflex, and 2 bags of very strong Antibiotic diluted in IV. Now man is bleeding from rectum and has a yeast infection on the . Man has no Health Insurance and does not know what to do. Man has become extremely depressed. Please Help him!!!
