Thanks for the advice! How often would you suggest to have a b12 shot?

hi,well may be you didn't peneterate upto muscle.Please take some pain killers like ibuprofen,diclofenac etc for 3 to 4 days and apply hot pad over injection site.
If the site of injection feels warm or hot to touch,probably it is the beginning of infection,in that case see a doctor for antibiotics prescription.
bye and take care!
