Sounds like some of the oil is getting into a vein somewhere. This can occur even when you aspirate properly. How many times has this happened?

Last week and this week. So twice. When i asperate no blood so I know i am not in a vein. Maybe the needle went though one is this bad?

Yeah, when we aspirate it is basically telling us that we are not going to inject directly into a vein but if we say go through a vein while putting the needle in then some of the oil could find it's way into that vein and then you would get the cough and taste. It's nothing much to worry about as it isn't harmful to you. Just more of an annoyance. Try different spots on your left glute and I'm sure you won't have a problem in the future.

Aboot I have one more question? I shot in the thigh 2 1/2 cc with a 23 gauge 1" man how the hell do you do it. It went in like butter but for 3 days I was limpin man! by day 5th day it was ok.

The more you do it the more your body will adjust to it and the pain should lessen each time. You can try massaging the area post-injection, heat it, etc. but in all likelihood the more injections you do the less severe the pain will be.
