Being feeling cold all the time. Never hungry or eat very little. Sometimes get pains in my tummy like sharp pains. Sometimes I feel sick without being sick. But other times I am sick. What could these be signs of?

Evaluation.. If you google your particular symptoms, you'll find they can coincide with just about anything under the sun. That can be scary! but sometimes people just have these little aches and pains and symptoms that turn out to be nothing. The only way to get it sorted out is to have a thorough history and physical exam by your doctor. Best of luck!
