Recently diagnosed with bronchial infection. Given inhaler, antibiotics, steroids, and cough meds. Just got ALL in system (day 2) and now have throbbing pain matching my heartbeat across back - lying, sitting, or standing. Uncomfortable enough that it has me worried.

I think it is time to call back your doctor or go to the ER.

My friends who have this year's flu all tell me that it hurts horribly across their diaphragm.
Do all the home remedies. Drugs are not a substitute, even if it's bronchitis.
Tons of liquids, rest, warmth, and humidity!
