PIO shot burning a couple hours after shot

T

I’ve been doing progesterone in oil shots for the last 3 weeks or so and they haven’t been bad. Tonight in the area I got my shot it’s kinda burning and uncomfortable like an hour or two after the shot. It’s a new bottle, I just got a new shipment in and it was kinda warm when I got it and I know it’s supposed to be room temp so idk if that messed with it. But is the burning normal? Has that happened to anyone else?
