Why am I not even sore from PIO shots?

I was dreading these shots based on what everyone told me about them. But I'm two weeks into taking them and as of 5 days ago I don't even get sore from the shot 🤔 It feels the same going in.. a little weird pinching feeling in my muscle. But in the beginning it hurt so much to even walk. Now I don't feel anything. I know I should be grateful but it's making me paranoid. Anyone else not bothered by the shots?
