Hi, found this site on the web hoping I can get some insight.
I noticed everytime I get a B12 shot in the rump, I'm out of commission for several days. It's so painful I can't even sleep at night. It's like a knife stabbing me if a move. And it last for about 3 to 4 days. B12 is very low so Dr gave a prescription for shot every week at 5000 units each. It even makes me nauseated and my appetite is low almost like a flu symptom.
Has anyone else had similar problem? The pain in the rump is the worst like a knife or pinched nerve.
