I started 1,000mg twice weekly injections six weeks ago. I had a resurge of all B12 deficiency symptoms in first 10 days and then they all subsided. However in last few days the burning throbbing sensations in my feet have returned ☹️ And this morning I woke with a headache.
Can anyone please let me know what this return of symptoms indicates? Could it be that other nerve groupings are being healed or is this wishful thinking
