Post Injection Pain

Hi all, I’ve read couple of things mentioning massages and heat packs in references to reducing post injection pain, for me, this does nothing, the swelling in my glute area is ridiculous for about 2-3 days afterwards to the point where i can barely put my shoes own because it stretches the area even effects me when training legs.

Is there anything before/during/after injection that can reduce this pain. Or do i need to tough it out, will the pain become less the more i do it?

Cheers.

Warming the filled syringe under warm water before injecting will help. Massage the area after will help.

First time injecting an area it will be rough. I have never used Sust but if there is prop in there is is probably gonna suck.
