For about six months have had constant dry cough and now have had swollen tongue, dry mouth and throat and a burning sensation on tongue, lips and gums. Also feel sometimes like something is stuck in my thoat only on one side. Have been to dentist, internest and ENT. All have said they can find nothing wrong. The one side of my throat always feels swollen and jaw sometimes feels tender on one side. I have also had itching on both sides of jaw closer to ears. Cough did eventually go away I think because of being on flonase. I have been on prevacid for years for reflux and I have been on synthroid for years and they keep increasing the dosage and recently on same side as other problems have proptosis of one eye. I am very frustrated and have very low energy despite being on correct dosage of synthroid. Any thoughts?
