Would repeated insulin shots in stomach cause muscle cramps?

Abdomen, not stomach: You are injecting in your abdominal subcutaneous tissue - not your stomach. The needle would have to be six inches long to tet to your stomach. Won't cause cramps. Make sure to rotate your injection sites. See a nurse educator for more information.

Unlikely: You don't inject into the muscle, you inject into the "fat" on your abdomen so it shouldn't cause muscle cramps.
