Hi, I've been injecting heparin for about 3 months since I found out I was pregnant. I've been lucky enough to have very minimal bruising. However, last night I noticed a small lump under the skin near an injection site where there is a little bruise, it's about the size of a pea. I'm assuming it's related to the injecting. Is it because I'm using sites too close together to inject? I kind of do favour certain areas for the injecting, my right side is definitely easier! But I try to alternate as much as possible.
