One of the most common concerns when starting injections is where to put the needle. It seems like it should be complicated - I mean you're putting a needle into your skin or muscle. Well, it's actually not that bad. There is a fairly large area where you can inject the medicine, depending on the type of injection. These articles on subcutaneous injection sites and intramuscular injection sites can be helpful, and of course, don't hesitate to call your doctor or nurse with any further questions.
