Hi im 19 years old and I have been having horrible stomach pain which makes me nauseas to the point i sometimes throw up. Sometimes I get heart burn so bad I cannot move.. I feel bloated and I often have to urinate or I'm constipated..I am having horrible back pain, tired and sometimes when I bend over I feel like a knife was stabbed into my lower left abdomen. I am pretty good about eating right because i have lot of food allergies so fruits and legs are all I mainly eat I also quite cigs and occasionally "Vap" not at all the real thing but I've been replacing smoking with exercise. also I've been experiencing a lot of pain in my vagina. Im not sexually active so I don't understand why I feel a sharp pain and I am late on my periods and lately a lot of discharge ..Whats wrong with me :(
