Hi, Welcome to Healthcaremagic.com. I had gone through your question I can understand your concern about your sore throat and lympadenopathy. You need to change the antibiotics and opt for injectable one like fourth generation cephalosporins, because these are mostly sensitive and less in side effect at higher dosage. One thing you must remember that the medication must be changed or taken under the supervision of doctor because there are chances of allergic reaction too. The enlarged lymph nodes are because of acute infection and will regress with the infection too. Hope my answer will help you and visit us back if you have any further queries.
