I have been experiencing moments where I feel I am going to pass out. It comes with numbness in my hands. I have twice collapsed at work. 2 times to the emergency room. MRI s, XRays, Ct scans, full blood work up, 9 ekgs. Some is contributed to my neck and back. I had a broken neck fused a few years ago but need another in my neck and L2 to S1 fused. I had my neurosurgeon inject my spine last week. 3 times yesterday I felt like I was going to pass out. I take prescription meds for blood pressure and Protonix for heart burn. My team of doctors still unsure? Sorry so lengthy.
