Hi There,
The Internet sure can be a scary place! I am glad that you are going to get checked up. At your age there are several very
commonCommon cold conditions that I would think about:
Irritable bowel syndrome causes cramps, pain, bloating. It is worse with stress and certain foods.
Gyn conditions: infections, endometriosis, pregnancy,
benignBenign ear cyst or tumor
Benign positional vertigo ovarian cysts.
Cancer is just about the last thing I worry about in your age group. However there are many benign conditions (as listed above) that can cause alot of suffering and can easily be treated.
take care
