Hi everyone, since November of last year I have had a recurring issue with a one-sided sore throat and ear infection-like symptoms in that sides ear (can hear wax moving, wet occasionally, etc). It usually goes after about a week but my lymph nodes usually swell slightly with slight tenderness when it's it's around. I assumed it wasn't an ear infection because it goes on it's own, but this is the third time I've had it since November. Any chance of this being serious?
