my first injection caned like a bitch. the second one wasn't as bad but still stung for ages. the third injection was pretty good, no real pain in the long-term.
but i had a hard little lump under my skin for quite a while from where they jabbed me all three times, although there was no bruising.
it was like feeling a tiny ball under my skin. i'm so glad there will ever and only be three injections.
