I have been using HCG for about 4 months. I am injecting SQ in the stomach area. When injecting a couple of times, I got a dime size bump. First time this happened, I just pressed on the bump to make it go down, second time I did the same but got a large bruise that subsequently went a way. Any idea what I am doing wrong? If it happens again, should I just ignore it because it will ultimately be absorbed? Use a 27 gage 1.25" needed because I used to inject IM. I insert the needle about 1/2 inch into fat. Thanks for you help.
