I have been feeling a pain below my breast for threeFAMILY days and it has been moving. The pain is moving toward my back and through my stomach. I just got over a cold and I do not have my period, so cramps aren't  a option. Due to the pain, I have had a hard to time eating and moving in general. If I move in certain positions, the pain strikes. I feel like vomiting sometime and I normally get headaches. Please tell me what it is? Hopefully its just muscle pain.
