i just did an injection of test with a 22 guage needle. i put it in once and it started bleeding, so i took it out with out putting any test in and put it back in the buttocks next to the same spot. after the injection i noticed a puffy bumb. i'm not sure if the test didn't make it in the muscle, or its just aggravated because i made two injections or what. please write back so i know what i should do.
