Well I have had stomach aches like cramping and bloating on and off after I eat and or drink. I have had more gas then usual. Fatigued and also feel really hot. I'm 21 years old and not pregnant... Also the other is on my right inner breast Is what looks like a pimple or bug bite very red and my breast itches.. Excessive urination and hungar and thirst. Hard to catch breath sometimes and dull sharp pain in the lower right side of my chest and under belly button. Should I be worried

Worried? Not yet, but get yourself to a doctor to find out what is going on.
