Pain in L jaw and L shoulder that radiates. No fever or congestion. Intermittent extreme dizziness and pallor. Intermittent pain in chest. Bad headach?

See MD. Even at your age and your sex, see and MD or ER NOW to rule out cardiac pain.
Nonspecific signs. All these symptoms are bizarre and not specific. I would like to know whether there is any history of trauma? If so, concussion should be thought about in the differential. You are too young to suspect a cardiac problem unless there is an obvious risk factor: drug user, hypercoagulable disorder, etc. You need to be examined by a doctor and a good neurological exam and cardiac exam done.
