this is my second episode of this its identical to this first one. it last about a month or so. I have reallyh bad ear ache that radiates down my neck to my collar bone. it causes discomfort under my jaw area and under my chin to the front of my neck but only on my left side. i also get a bad sinus infection on the same side then it all clears up and the pain slowly goes away. ive been to the ent,er,oral surgeon, dentist and md. ive had blood test(basic) and a ct with contrast pano xrays, oral cancer screening with the blue light.all came back negative. and no tmj as well. so no one knows the problem. it was suggested I maybe should see a chiropractor. can any one please help me.
