Go to ED: Its hard to diagnose these symptoms without a good history of your recent activity, how athletic you are normally, your medical history, list of meds, and a good physical exam. I suggest you go see a doctor, either your GP, a doctor at an urgent care center, or an ED at a hospital to get a doctor to examine you to see what's going on

Exam: You must be examined and have comprehensive blood testing. Your symptoms are quite peculiar and deserve further medical evaluation.
