I had bronchitis and was prescribed antibiotics that worked well about 3 months ago, about 3 weeks ago I caught a minor cold but have had a cough since, I have wheezing in my lungs, I'm coughing up white to clearish phlegm, I feel a tightness in my chest, and chest soreness. A doctor I saw at a walkin clinic gave a steroid inhaler which helps a little but not for long. I am 20 years old, I'm overweight but am a former elite athlete who has traditionally exceptional blood pressure and breathing
