Kevin1234: MY PAIN IS GONE!!!! so Kevin. let me tell you my experience. have had terrible pain both ears for 20+ yrs when I sleep on them, especially the right ear. dr sent me for xrays, to Ent, to another Ent. no one had answer all looked at me funny as if I was nuts. also have acid reflux and very bad allergies for which I take generic Zyrtec. in meantime allergist retired and new one said we have a pocket of cartilage behind each ear which probably had become inflamed for all those yrs. that's why when I would massage behind ear gently at first then aggressively I would hear crackling. new doc said that was the cartilage breaking up. about 2 yrs ago I told my old allergist about getting very sick after plane ride. he suggested doubling up my allergy pills. BTW this allergist also had no answer about ears. because the next allergy season was so bad I kept taking double dozes of pills. I first noticed (about august of 2019) that my left ear was no longer painful to lay on. still did not make connection. then about 2 months later (late september 2019) the right ear was no longer painful. UNBELIEVABLE…..after 20+ years!!! but, during October, I had a very bad allergy day and my right ear (which had been the bad, bad one) started to hurt when I laid on it. so I decided to experiment. stopped taking allergy pills (in past only took allergy pills in summer). it took approx. 3 weeks (just a week ago) that my pain came back not as bad as before but bad enough to notice and only in right side. I got so scared it was coming back that I got up from bed and immediately took allergy pills. next day it was gone again. so….what does that tell you? I think everyone has this pain for different reason, but perhaps someone might have for same reason as mine and could benefit from my experience. BTW, your reference to acid reflux is very interesting and could very well be an answer for others.
