I self-injected for the first time this week. Up to now I was getting weekly injections at the doc's. They used a 1.5" 22g needle for the delt. Depending on nurse's skill, I would have no post-injection discomfort at all. To do my own, I tried a 1" 25g needle. I have very little fat over my quads and the needle went in painlessly. But it took about 15 seconds to inject the 150mg. I was surprised at the resistance from the ester. Have injected B12 many times and it is in and out in just 5 secs or so.
I have had injection site pain for two days now. No big deal. But I am wondering why I never had the same kind of pain with the delt pins. Is it the muscle tissue, or the time it takes to deplete the syringe given the thickness of the liquid. Or perhaps I injected too quickly, though it is hard to imagine given the amount of constant pressure I put on the plunger. I think I will try a 22g needle next time. Should lessen the injection time and may better disperse the ester than the 25g as well.
Anyone have a similar experience - smaller needle - post-injection discomfort?
