Hi. I had this ear pain and pressure so bad. I went to the ENT doctor and they found nothing. Then I went to my neuro who did an MRI of my brain and ear canal which also found nothing. I have severe eye condition and often it feels like the pain and extreme pressure like it will explode is starting from the eye. They were concerned with something pressing or fluids and it turned out nothing. I am not sure if it is from my meds now for the rsd or just time but it has got a lot better. I still have ups and downs but not the daily crying pain. I had to accept that for me there was no dx same with my eye condition where I have been to 11 eye specialist,neuro,etc etc and 50 plus apts. If you don't get answers or relief I would go to a neuro. There is such a mix from the doctors I have dealt with about rsd in these areas said no not in the eyes.I still have heard others have it there and no one can figure out why I have such high pain as blepheritis and dry eye does not cause it this high and that was the dx. Anyhow hang in there and feel better
