Perhaps a heating pad or hand warmer on the injection site would ease the ouches?
Also, don't tense the muscle you are injecting into - that causes pain after the injection. I learned this after feeling like I had the flu for weeks from my B12 shots a long time ago and had forgotten about the need to relax the muscle getting injected...
I hope this helps - take care,
