Back to the huge 2 inch needle on the shot - yikes it hurt! Of course my DH is saying don't clinch and what did I do? Clinched up! How can you control that? My mind is sending signals to my body is saying "don't do this". I guess I forgot how painful an intramuscular shot can be. My hat goes off to all the girls who do intramuscular progesterone shots. All my progesterone has been vaginal suppositories. I was limping around last night and my booty still hurts today. I think I will use that and the rain for the reason I didn't go for a run or get on the elliptical when I got home from work.
