Oh Jen, how scary AND frustrating. I'm so glad to hear that you finally were seen by a dr. that gave you a decent workup. When you had the hot spell and felt faint, were you experiencing pain in your neck and shoulder? Were you exerting yourself? Sometimes intense, sharp pain can initiate what's called a vagal response that might cause you to feel faint, break out in a sweat. If it happens again, in the absence of pain, or with exertion, I would definitely go for a thorough workup which would include more involved blood work (caridac enzymes) and an EKG. Are the xrays for your neckand shoulder? Carpal tunnel can be such a misery A non surgical approach would be a great first step; can't hurt! Please keep us updated! {{HUGS}}}
