I was on cephalexin for folliculitis. I then got strep throat while I was on cephalexin. I had the penicillin shot. Then I continued to get more sick. I have a cough with sputum, hoarse voice, sore throat in mornings, stomach pain in lower abdomen, slight loss of appetite, and extreme fatigue. I had bloodwork done and it showed that I had a virus, but we are not sure what virus. Also, the strep is gone. This has been going on since last Wednesday. Any advice?
