Hello again,
I see from many posts that recovering from B12 deficiency is not a linear process of just getting better. I am certainly experiencing this and am increasingly confused and alarmed by it.
When I started my B12 loading doses I had only just started getting a mild neuropathy in my hands, and interestingly in my mouth. My loading doses were not perfectly administered as I realised I needed them quickly and had a 2 week holiday booked. I had the first week of every other day, went away, came back and had another week. I started on a third week but these loading doses were more spaced out as I felt very agitated after them (I assumed as my B12 levels were getting high). I went on to 2 monthly feeling that my neurological symptoms had been alleviated, but some symptoms returned before the 8 week mark (not the neuropathy). I had the next injection and after this the neuropathy returned, as well as tingling/pins and needles all over my body. This didn't go so I had another injection after 3 weeks. This didn't improve anything, in fact it made me feel agitated again like I had done at the end of my loading doses. Two weeks on from that injection I now feel very anxious, really tired and a bit off balance, with tingling still in hands feet and all over.
I really don't know what to do. I don't think I can stand another dose of B12 yet (was going to wait 4 weeks), but I fear that if I don't my neurological symptoms won't get better. I had been feeling great, despite some tingling, but now I don't even have any energy. Could this just be the healing process or things getting worse? I believe neurological symptoms and anxiety like to hang on for a while, but really this long (it has all in all been 5 months)?
Sorry for the long post. But really I don't know where else to get any help on this. My GP is great but this is also new to her. Any advice or experiences welcome.
Loading injections finished but symptoms still here and getting worse
Aches and Pains Getting Worse - Low B12
Why you get worse before getting better after B12 shot.
Feeling worse after loading dose. 
Is it Usual for Neuropathy and Pain to Get Worse with Age?
my situation has been very similar to yours...... I felt so so awful after first few loading doses that i really wanted to give up as was frightened how bad i felt....but i decided to continue with every other day if not daily injections and now the anxiety has gone, i have more energy and the neurological symptoms are slowly improving, although worse on some days and improved on others....it seems this whole healing process takes time, sometimes getting worse before it gets better. J
Thanks for telling me your experience, it is very helpful to hear. I really am finding this difficult. I was ok when things seemed to be getting better, but when it gets worse again it is difficult to rein in the anxiety. I hope that things start to improve again soon.
Again I caneed relate to this . On a good day you think right I'm on the road to recovery. Then it gets so confusing when anxiety returns and sy motifs all over the place. What seems to work one day for me doesn't the next. I feel I've achieved something if I've been downstairs to eat or moved around more. I'm very slowly improving. The anxiety csn be deskthe with by thinking of worst symptoms that have passed. It all seems part of this. Before B12 defiency I was not an anxious person infact a very busy carer. I sniff lavender on a hankie if it starts. Breathing exercises csn help. It is difficult. Uses all myour strength to keep a lid on it. I keep a diary too.
I wish you well
Also I got alot worse after injections started. Dreaded each one with what it would bring. Had side effects bad rash ect. But they did heal and I'm now even though dreading in a way know I need the next one. I'm hoping as a one off rather than loading it wonth be as bad
It is hard isn't it. I find it especially so when I have felt better, and then I get a bit worse again. I'm sure we will all get there, just more slowly than we expected.
