I have injected EQ up to 1 cc into each calf, never any more than that, and yes a couple days later, it really hurt bad for about 3 - 4 days and impacted running/walking. I even dreaded getting up first thing in the morning out of bed.
Felt pain most down low, near ankle, I think similar to what some bros have posted several times when they shoot in quad, and they feel severe pain around knee?? I can't explain.....
3 cc in one calf, is that true, or did you do 1.5 cc in each? That makes me shiver just thinking about it. You must have some big calves or a masochist!
