I experienced major
bruising with my second injection. It started
bruising about an hour afterwards, and by the next morning it was the size of an apple. Black and blue and angry looking bruise! I also inject into my abdomen. A nurse friend told me I might have hit a capillary, and my doctor saw it days later, and told me to keep an eye on it. It ultimately faded into just a big red mark. It never did hurt or anything, so I never felt in danger, but it was bizarre.
