Okay for the last 3 months or so, I have been getting bad, bad pains. All over. But mostly in my lower region. Like my abdomen. Or backside. But I can get them anywhere. Like my hand, chest, head, feet and legs. The pain is sudden, like a bullet. Sometimes it pulsates for a few seconds. But it never lasts more then a minute. I have been healthy all my life, except for migranes and a heart murmor. I have been athletic, I really dont know whats going on. The pain is sometimes unbearable and gets me wondering if I should see a doctor, or go to the hospital. Im not sure if everyone gets body pains though. I am 17, just graduated, I dont smoke, I have only drank alcohol like three times. Im not overweight, just an average teenager. Also, sometimes when I go to get up I feel lightheaded, like my BP is low, and I have to sit there for a few seconds. Or if I dont eat for like 3 hours I will get shakey and weak.

Any ideas about whats going on?
