My husband s shoulder began hurting after a quick movement last Thursday. The pain has slowly gotten worse, and is even tender to the touch, and on Saturday he began running a low grade fever. This morning, Monday, he realized that there was a red oval red swollen spot near his bicep, about 21/2 inches wide and 31/2 inches high. What does it sound like to you? He did receive antibiotics from the doctor, but the doctor never really said what he thought it was.
