@bkour Yes, there is a good reason for injecting into the stomach/abdominal area rather than the thigh. The injections are meant to be subcutaneous—just under the skin layers and not into muscle. For most of us, the abdomen is perfect because the skin and fat are loose enough to be pinched up, thus making a perfect injection site. Yes, you can use the thigh as long as the skin can easily be pinched up. The medication should NOT go into the muscle! And, also, you want a wider area to choose an injection site. The thigh really isn’t suitable.
Are you having concerns about injecting into your abdomen?
