Cough, chest congestion & wheezing w/ deep breaths for ~3 wks. Cough can be aggressive @ times & barely productive. When productive, phlegm is thick.

Seek help asap. You will need to see a doc ASAP. Antibiotics, bronchodilators , possible admission are in order. Probably all viral but if fevers and xray show anything they might start antibiotics. Meanwhile, keep yourself well hydrated. .
