The thigh is another area where the insulin injections can be injected. The best area to inject in the thigh is around four inches above your knee. Remember to avoid putting the injection around your inner thigh area as there are a lot of blood vessels as well as nerves around the inner thigh.


You should remember to avoid the lower portion if you are planning to apply your injection in the buttocks region.


Inject in that area of the stomach which is at least a couple of inches away from your belly button. Also, keep away from any type of scars, marks, etc. while you are injecting insulin in and around your stomach.

  • However, for the same type of meal, it shall be helpful if you are injecting the insulin injections around the same area.
