There's something like tongue like structure in my throat, what do you call this? i think it's swollen or enlarge, i feel it every time i swallow.

Lump in the throat: Feeling a lump in your throat w/out cause may be Globus Pharyngis. The most likely reason is anxiety for which you can seek psychotherapy. To get DIY relief, gently warm your throat w/ a cloth and then w/ posture straight, stretch neck back till looking up. Do slow tilting/rolling of head and gently massage the tightened muscles on neck sides lengthwise till they relax. Best!
