Have painless lumps on the back of my throat and back and sides of tongue, when i swallow sometimes feels like something is stuck, swollen lymph nodes?

Dr. can check throat: Throat symptoms with swollen lymph nodes can be from a strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies, irritants, or stomach acid reflux. Usually, a person sees the doctor if the throat or mouth symptoms are bothersome, recurrent, or don't go away quickly (mainly to check for strep throat).
