I have a cut on my finger that became a blister that started spreading. After going to the Derm and ER, I remain in pain. The pain in my muscles is as though I worked out all day lifting weights. They have switched my medication 3 times. Now on 2 antibiotics and a steroid. The diagnosis is a staph infection but the pain in my right arm, shoulder, and scapula does not go away (although the swelling did). Please help! Very worried.
