How does movement of a muscle help with intramuscular injection pain/recovery?
In: Biology
Intramuscular injection a leave behind the injected solution in the muscle. The goal is to diffuse the solution into the blood slowly using the tiny blood vessels that weave through the muscle fibers. The pain comes from the fact that you’ve filled that space with extra fluid so there’s a bit of pressure. In order to relieve the pressure that fluid need to enter the blood. By flexing that muscle you promote blood flow and increase the rate which that solution makes it into the blood stream, thus getting rid of the pressure and pain faster.
