The stomach area is usually better because it has a thicker fat layer and fewer nerves than the thigh or glute, and the tissue stays steadier so the needle meets less resistance.
Four weeks into Reta and every shot had been basically painless until today. I switched to the other glute and the needle pain was so bad I couldn't push it all the way in. I pulled it out, drew a fresh dose with a new syringe and needle, but inserting still hurt way more than usual. After finishing in the bathroom I got hit with a vasovagal reaction—vision went dark, hearing faded, and I felt extremely lightheaded. This reaction hits me during most blood draws but had never happened with peptides. Any ideas why it was suddenly so painful when nothing else changed?
