I have a throat issue, feels like something is swollen in back of throat, not sore just swollen feeling, food gets caught too. any ideas?

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see a doctor, preferably an ENT doctor. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs.
