Hello

For a a few years now my ears (mostly the right one) get blocked. There's nothing I can do to unblock it exempt lie down or put my head between my legs which instantly unblocks it.

My jaw aches a little and I occasionally get a runny nose. I rub my jaw near the ear with muscle relaxing balm which at times gives me a little relief but doesn't fix the problem. I wondered if it was a sinus problem so took medication to clear the sinuses which did not help at all.

I just want to understand what the problem could be.
