I just got over the flu nand stomach aches and now i feel like theres a lump in my throat. i threw up twice today what is the lump never had it before?

Feelig throat Lump: After vomitting, the irritation from acid from the stomach can give you a feeling of lump in the throat. However after flue like symptoms, need to be checked for tonsillar swelling including abscess. Need to go to emergency room immediately if you feel shorness of breath. If not, advised to see your doctor if symptoms persist. Be well.
