Since many months, I have difficulty swallowing food. Liquids and semi liquids are fine, but difficulty with solids, especially chewy ones. Jaw feels tired and painful after chewing too much. I also have a feeling of fullness and tightness in my throat after eating. I have tried bacterial infection medicines, allergy medicines and GERD medicines. GERD medicines seem to be making me feel a little better but the symptoms still persist. Please help.
