Dermatology Questions? Ask an Online Dermatologist.
Hi and welcome.
The symptom you described can be due to few reasons the most common cause can be either stricture in the pharynx or pharyngeal muscle weakness. These are treatable conditions. I would recommend you to visit a gastroentrologist for thorough examination and you might need an endoscopy that is examination by an inside camera.
Let me know if you have further questions.

Sorry above is answer to another question posted here by mistake.
It could be herpetic gingivostomatitis caused by Herpes simplex virus type 1 (HSV-1). You should see your doctor or a dermatologist to have exam and test. If so, you should have anti-herpes viral medication.
