Welcome in H.C.M.
I read your query regarding swelling around your left molar and left tonsil
and enlarged inflamed tonsil both hurt during swallowing. You should make your X-Ray OPG to know about un errupted molar, because more often wisdom tooth are misdirected and wrongly placed. If in X-Ray wisdom tooth is found misdirected than you should seek treatment by dentist
As far as tonsilar selling is concern that will responds to antibiotics and anti inflammatory, but if you are not getting proper response than ent docter should be involve in treatment for getting desired results
