When I came to the reality that the only place you feel the sting of the needle is the first layers of your skin, (everything below doesn't have nerve endings) I was able to inject myself without any problem. What made it even easier was I found this spray on Amazon, cold spray, that is made specifically to numb the area for a short while, so that the injection isn't felt at all. So I spray on this stuff, wait a minute and my leg is numb. So its a no brainer to inject and except for that little twinge when the muscle jumps sometimes, there is zero pain and I can inject myself without any problem at all. The spray can is pricey, can be $40 other less cold spray is around $10, but it does the trick for those who are fearful of the sting of the needle.
