Coughing up thick mucus with sore throat , if feels like my throat is closing and i have no fever chills or aches. what could this be?

Possible allergy: Your symptoms may be due to allegy and you can try over the counter allegrad, claritind etc if persists see your doctor or an allergist.

The consistency: And description of mucus does not tell its cause. Tightening of your throat may have serious consequences, including laryngospasm. You should get examined by an otolaryngologist.
