question: My husband has had a fever from 99 to 102.5 since last Sunday which has been 6 days ago. He has chills and cold like symptoms. He has gone to the Dr. twice now. The 1st Dr.(walk in clinic) put him on Amoxicillan, he took the meds for 2 days still running a fever and went to our regular Dr. and they put him on a Z-pack. He has taken the 2nd dose of the z-pack but is still running a fever. By the way the clinic took a flu test and it came back negative so she said is sounded like a sinus infection. We are just concerned with him still not feeling well. Could this be the flu or just a cold?
