Today's injection was set to be in the left quad, but I wasn't able to inject in my quad. When I tried the first time, I wasn't able to pierce the skin. I tried a second spot close to the first and was able to pierce the skin, but barely and the needle wouldn't go in. I tried one more time and, again, wasn't able to pierce the skin. At this point, I changed needles and injected my delt instead.
I doubt I have that much scar tissue in my quad. I haven't had any serious injuries or ever had surgery of any kind. What could be the cause? I'm not overly worried, but kinda concerned about losing an injection site already.
