I will get checked and dr would give me antibiotics for 5days and I take those and it gets better. For me Ear infection comes with ear ache, snapping sounds, sometimes discharge... and headaches. Sometimes cold air or ac or keeping the fan on through night can bother my ears. As long as sinus is there ear problems are common... so focus should be on treating sinus to get rid of ear problems. I always focused on fixing ear and also ended up w surgery.. to realize I have sinuses that’s creating ear problems. And if sinus was under control I wouldnot have gone to the stage of surgery... a good Ent will evaluate after all scans and after performing tests.
