I have a very bad earache. My ear is visibly swollen on the inside and red but there is no apparent center to the swelling to indicate a bug bite or pimple. It hurts to swallow sneeze or do anything that cause movement in the eustachian tube. This has been ongoing for 5 days now. What is going on and what can I do to stop this. (please don't suggest a doctor or hospital I can not afford either and both require payment at time of treatment in my area)
