I would be interested to find out what your ENT says.
about 3 years ago, I would get this horrible pain in my right ear when certain weather fronts come in. At time the pain maybe manageable other times the pain gets so bad that if I touch my right ear it will send pain shooting through the side of my face down my neck.....the pain is so bad that I just stiffen up and breathe deeply. I get this several times a year now.
It started after a serious sinus infection, I didn't think it was fibro related.
