Hi, I have a question. I frequently (around 2-4 times a month) experience pain when I inhale. It s always a sharp pain, and it can last anywhere from just one breath to several straight minutes. The pain is always somewhere in my upper chest, back, or side, and it doesn t matter what my diet or exercise or even the position I m in when it happens. It s been happening for as long as I can remember, and it happens to my mother and sister as well, so I always assumed it was normal until I told my friend and he got concerned and said he had never heard of that happening to someone before and that I should ask a doctor about it. Is this something I should be concerned about? Thank you very much for taking the time to answer this.
