| Maybe you hit a nerve, or maybe something has your nerves in the area oversensitized so they are hyperreactive.
If that's the case, switch to a different body part for a while.
Another trick that helps me is to lightly tap the area where I'm going to inject with the needle before I push it in. If I feel something I choose another spot. This really helped me.
I don't go in at an angle, but I do use a very thin very short needle. Originally the imbecile diabetes nurse at my doctor's practice prescribed a huge railroad spike for me which might have been useful to someone with two inches of body fat and the hide of a rhino, but was horrible for me.
After reading Dr. Bernstein's chapter on needles, I asked for a short thin needle (which the imbecile nurse had never heard of!) and that made a huge difference. I currently use the 31 gauge 5/8" needed and the syringe with 1/2 unit markings since I use small doses.
