Thyroid,i guarantee it.When min started it felt like a chip was stuckin my throat every time i swallowed any liquids.It hurt really bad.Ive been on synthroid for 2 years and havent felt any pain since.Get your thyroid checked.
How long has it been going on for? If you are having troubles breathing because of this, I would encourage you to see a doctor, possibly an ear, nose, and throat specialist. Do you feel anything on the outside of your neck by your throat?
