Im seen as quite thin (118lbs 5'5) but sometimes lately I have a double chin ?

Question

Ive been really sick with a cold, and coughing til I throw up...could this be why?

what could be other reasons?

Im 17

Answer 1

you're nearly my exact measurements, I'm gonna assume that your lymph nodes are totally swollen and your throat area is experiencing the same condition.  

Try drinking tea and having a sauna, it'll at least help with inflamation.
