I keep injecting into the wrong spot. Usually how I know is it feels harder to push the plunger down on the syringe. And I bleed a little upon removal. How I find the spot is I feel different spots on my leg to see if it flexs, I find the spot and mark it. Disinfect it and inject. Usually turns out fine but these past two times I’ve been bleeding and harder to press down the syringe (as stated) and I don’t know what to do.
