I have the tingling and burning in hands and feet, started about 10 years ago but is now in my entire arms and legs often. Also, stabbing pains, chronic fatigue, bowel problems, electrical shocks throughout the body, numbness in all limbs, huge memory problems, and difficulty thinking clearly. I have had a couple MRI's and am told that it looks normal for someone my age, 49. I'm concerned about getting the spinal tap but must get it done. Or shoud I do the scan of the spine first? If it weren't for my faith I would be scared to death.
