You guys may really be on to something. Thank you for such thoughtful responses! I mentioned the slipped disc idea to my mom, rhubarb
, and she told me that she has something called cervical spinal stenosis, which can be inherited. Her's is caused in part by her physiology -- a narrow shaft for the spinal chord -- and was exacerbated by a bad car accident that she and I were in about 17 years ago. I'm scheduling a never conduction test this week, and I'm going to inform my doc of my mom's diagnosis. If it is cervical spinal stenosis it could explain a lot. Not only the tingling in my hand and heart palpitations, but the terrible sciatica I have. I finally realized that I am just too young to be in this much pain!
