Possible bronchitis. I had a small sneeze and runny nose for a day or two and about 2 weeks later was dx with bronchitis. No cold symptoms by then, just exhausted, back hurt and I was not breathing deeply. Get seen, it can turn into pneumonia. Take care.
I agree, sound like it could be your heart or lungs if not it is better to be safe and have it checked.
I agree. Get checked out quickly please. It may be nothing but nothing is good. Better safe than sorry.
I suggest you see your doctor or go to the ER and get it checked NOW!
It could be anything from muscle pain to heart problem.
