I am new to this site and have limited information. First, I have fibromyalgia. I started having tingling sensations, etc and was referred to neuro. I was told two months ago that I am b-12 deficient. I was not given the numbers. Had 3 shots threedays in a row and then to have one per month for three months and then recheck level. I am on the first monthly shot. I feel worse now than before starting shots and have more symptoms. Nero said it's just "repairing" and that's normal. I left in tears. Suggested add more lyrica. Already take lyrica, neurotin, and cymbalta. I make myself go to work, but that's all. I hurt too much and I am so tired. Neuro said do yoga -no energy. Was told not to take supplement until after next test. Any advice or encouragement? Thank you!
