Hi, I have posted before in last couple of weeks. Basically I had no real symptoms of b12 deficiency until I had routine blood test as I was on ppis. My b12 was found to be really low (85). I started on injections and had just 3 as I had bad reaction to them. I then went on tablets and sublinguals with the same effect. I'm now waiting for referrals to hopefully work out what to do. The thing is that I'm now getting loads of neuro symptoms which I'm sort of coping with! I'd just like to see if anybody out there has pins and needles on face lips into mouth and throat? I do find it a bit alarming and would like some reassurance if poss.
