Hi Heather, I saw your message about nerve symptoms after taking b12. I know your message was left many years ago - but thought I would try contacting you anyway. I was b12 deficient and experienced tingling in my arms. I started taking b12 - but got new worse symptoms. I stopped it 7 months ago but now have pulsating painful legs, twitching, joint pains, skin problems.... the list goes on and on.... and I'm getting more symptoms by the day. Please could you let me know if you made a full recovery and how long it took. It would be so helpful to know. Thank you Tamra (***@****)
