My right ear pains for 3-4 days, every year once or twice. I do warm compress and it goes away in 4-5 days. Somedays ago it happened again now it's gone, i even got a lump behind ear which was painful. Now everything is gone- no pain now, but the ear feels swollen. I don't know why. Some added issues: i have a really bad dandruff problem. Also i have one of my teeth in the corner decayed which i have not got treated and the hole has reached the teeth muscles. Please suggest what might me causing this problem!
