This time I did the shot on my left buttcheek. I'm not really afraid of the needles or the discomfort anymore. I use a slow insertion instead of a quick jab, but I'm starting to push through the skin a little more quickly since that's the most painful part and slower means longer discomfort.
The left side was definately more difficult, being that I am right-handed. I sat on the bathroom counter to get a good view of my left side. Checked and double-checked the correct location. Stuck it in, pushed into the muscle (slight twinge, not much) and slowly slowly depressed the plunger. Since this oil is thick it takes longer to get it through the needle and it was more difficult with my left hand than it was with my right. But, I don't think I have to worry about intramuscular injections anymore. They really don't hurt very much. As long as I can avoid getting hard lumps (inject slowly, massage and walk afterwards) I think I'll be just fine.
