I was detected with rhinopharyngitis about 10 days ago and was advised maxtra, doxcef cv and nasal drops twice a day for 5 days. While the condition improved, I experienced swelling on upper lip and constipation. Now again my right tonsil is swollen and hurts while swallowing. My right ear is again ultra sensitive from the inside and hurts as well. I can feel redness in my throat and have a runny nose. I have allergic bronchitis. Shall I take amoxicillin clavulanate? Need help!
