After being found to have B12 deficiency (206) and fighting with my doctor who only wanted to give me one shot, I found another doctor who was up on the effects of B12 deficiency. He gave me a prescription for 12 more shots weekly or until the pain in my legs started to recede. Well on he 12th shot, my pain began to release and I'm getting better every week now. I still take the shots but I take them every 2 weeks and if it keeps up, it will go to every month or more.
Along the ordeal, I lost the muscle mass in the calves of my legs to about 30 % of normal. I now have most of that muscle back. I can thank my current doctor for getting me back to a normal life and out of all the pain I suffered.
