I literally just did my (1ml/250mg) Test E injection. I have done it a few times without any issue, or any pain (23G 1.5in). I have actually come to enjoy injecting. This time when fully inserting into the glute, and pulling back on the plunger to check for any blood, as usual I only received a small bit of air and no blood- and then injected. As soon as I finished I had a very sharp pain, and I'm still in a surprising bit of pain.
I inspected the needle and saw that there was a small amount of blood trapped between the needle and the syringe, that I did not see when injecting. I'm bleeding from the injection site much more than normal (which is usually only a dot), and I seem to have injected a little lower than I usually do (but still in the correct quadrant).
I'm not one to be easily worried, but I have never had pain, or even the slightest amount of blood from injecting. I'm wondering if I should be concerned at all, or if there is anything I can do.
I'm guessing that I should be concerned, and that there is nothing I can do about it now. I will be back from the gym at 10ish, thanks for the feedback.
