For two months now my chest as been hurting and my breasts are sore and aching. I live in costa rica, I went to a Dr. and he gave me Nucleo C.M P. and Potassium 100Mg. also gave me an enjection. This was the 19th of Jan when I had my appt. I seem to be better but for sure as not well. Maybe I need some more Medicine. It don't hurt when I breath. Jerry. Any help appreciated.
