Hum...Im sure somebody will pipe in...I only take my b-12 sublinguily...what treatment are you on?

i take mine sublingually as well. Can you get someone to give you the shot? does it have to go in the behind? Can it go into the front of the thigh?

i take my B12 orally too. i see B12 is an intramuscular injection so i guess the outer part of the thigh might be easy:

I get one every other day. I get it with an insulin needle.Smaller than the ones we got with TX . You can do it in your thigh, arm or butt. I prefer the butt because I don't feel it later. No Big deal. If you lay down you can reach around and give it to yourself.

I've had an awful time with this. I've only done it twice -- once I did it, once my husband did. Each time I was in pain for days after. My whole hip was stiff and achy. Every movement hurt. Not great since I rely on exercise and yoga to feel good. There's something else in the shot, and the whole thing is 3 cc's of thick goop, from a very long needle. It sounds like just B12 doesn't have side effects, right?

I've never had sides from sublingual B12.

I only use the methylcobalamin or dibencozide forms of B12, as they are more easily absorbed. I also eat the very occasional small bit of fish, egg or butter, to get naturally the B12. I'm pretty sure that spirulina and chlorella have natural B12 in them.

If you do another shot, try a heating pad and massage on the injection site and the surrounding muscle of the injection. It sounds like your muscle is inflaming in a similar way to what happens with over exercise. You also might want to take some Wobenzyme or similar proteolytic enzyme to break up the injection so it doesn't form a lump that causes inflammation. Also, do a meditation and welcome the B12 into your body, and do light massage that sends it to the other cells in your body.

Thanks. I'll try the heat and massage.
