I was injecting Sust in my glute and couldn't! I was pressing in on the plunger and it wasn't moving at all! I had to really fucking push hard! I then finally had to pull out just a tiny bit and this seemed to help a bit. But still! It was fucking hard! Why did this happen? Also, can anybody direct me over to a website that shows how to PROPERLY inject? I've never had this problem before, but lately, it doesn't matter where I inject on my glute. I somehow also have blood drip out after I pull the needle out. This is happening WAY to much.
