Hi, I have had pain in my left ear and throat and headache (in the left side of my head only) for over 2 weeks now. I went to the walk in clinic on 6/12/15 (12 days ago) and I was given Amoxicillin twice a day for 10 days and over the counter Claritin for my sinusitis, I took it exactly as directed. I finished the bottle 2 days ago and I still have pain and yellow spots in the left side of my throat, in addition, I am now feeling dizzy and chills all over my body, cold hands and feet (unusual to me here at 92 degrees).
