I am a 15 year old male, non-smoker, non-drinker 140lbs, about 5'11 and i have recently been having ongoing chest pains in my right side of my chest (from just at the breast bone and up to my collar bone) the pain is mild to painful when im not breathing but when i take a breath the pain is very sharp and prevents me from taking a "full" breath.
I cannot sleep at night due to this and it seems to come and go as it pleases throughout the day< i've tried antibiotics but they didn't even put a dent in the problem. I have almost every symptom of a viral case of Pericarditis but it's in my right side as opposed to my chest. Can anyone tell me what may be wrong?
