I was gonna post the same thing today haha... had my first injection yesterday, did everything the same except i changed needles after drawing. 23 1.5 in the glute, no pain all day really yesterday, but today its gotten progressively worse throughout the day.... i can't even sit down straight, nearly to the point its giving me a slight limp. I don't know how the hell i'm going to squat tomorrow, i can't even do a knee pull to my chest at this point...
One thing I noticed is that its really hard to aspirate with a glute injection while keeping the needle still, especially if I go to my non-dominant side. Could that be it? I figure the more the needle moves when its inside, the more trauma its going to cause.
