Injecting - injection question

[yogotti]

I recently done some research and decided i would try my first injection. Ok i started off with a small amount and pulled back and seen blood and my girl injected me quickly. So now my problem is i just wasted a good line and i have a buldge under my skin that resembles a bruise. So my questions: would her injecting it quickly have caused the problem? #2 My other question is all i could find is 22 gauge needles, are those to big, because i read you are supposed to use a 29 or 30. Lastly she didnt untie the belt before injection because we was so worried about proper vein placement. Could the belt still tight on my arm play a factor in my miss. I just wanna know the cause if it was the size of my needle, or because we didnt undo the belt before injection, or both?? And can a successfull shot be done with a 22 gauge 1" long needle. Sorry one more ? my needles say 1, 2, 3 cc's Im worried i didnt use enough water. Grateful for any advice
