Hi l have just been told my B12 and Folate is low B12 150? I have had problems with what I think is my coccyx where there is pain when I sit on hard chairs and have to sit on my bum cheeks causing numb legs and severe sciatic pain down one leg. My right leg has caused problems for about a year now including my foot , my leg and foot are bigger than my left one and I have pain in my egs and feet especially after being in bed all night. I feel about 90 when I get up until I move around. I don't sleep wake up to turn over lots and don't feel I've slept. Reading posts on here I have itching legs/skin, eyes deteriorating, black floaters, always feel shattered and wake up thinking someone has knocked on door or shouted. Doctor has said all my pains should improve and my coccyx and won't send me for an xray yet. I am having a 2 week loading dose then 1 a month for 3 months then a blood test. I am told I will feel amazing by the pharmacist. Will the doc stop it when they are normal? Or will it slowly decrease again and symptoms return?
