I rotated to my quads for my HCG and Sust today. Sust went into right quad smooth as silk. However when pinning the HCG in my left quad I hit some snags.

1. It took some serious effort to break the skin.
2. Once in it as like traversing gravel, it was not smooth at all almost like I was hitting bone but thats obviously not possible. At least not at the depth I was at.

Has anyone else ever had something like this? Scar tissue maybe? I have zero PIP 5 minutes later but I am still curious as to what may have caused that.
