Lindy lou

I am being treated for TMJ by a specialist . My jaw was cracking everytime I opened my mouth and the pain was terrible. I had retainers put over my teeth for 7 months to get the jaw back into position. The cracking joint has healed but I am left with a feeling of water running in my ear like a bubbling feeling everytime I put my head down. I have had a sinus scan nothing there. Tried nose spray still doesn't help. Saw an ear specialist who says the feeling is reflux and was given Losec. This too hasn't helped as still get this feeling .The TMJ specialist said it is the joint and to see an osteopath and he was certain it would be fixed. I have booked into see one next week. I am getting myself in a real tiz about the fluid feeling as flying to the UK next month. Does anyone else out there have this feeling of water in the ear when they put their head down. Sometimes it also makes me a little off balance for awhile as well. Have had that all checked with the ear specialist who says everything was okay. would welcome some help here.
