Hello, my boyfriend was recently diagnosed with bursitis. He has been in pain for the past two days with no relief. He just moved his arm and instantly his elbow felt better, but he says he smelled something funny. Now I m worried he had infection bursitis and the sac has ruptured and could go into his bloodstream. He is on Keflex and another antibiotic as a precaution to treat for MRSA if that was the case. Should we be concerned or is this something that can wait until the morning to call our PCP?
