Occasionally, when SWIM injects, something strange happens. At the injection sight and all along the vein, his skin will inflame and protrude. It looks similar to a miss, but it is not a miss, and has nothing to do with technique. For example, if SWIM hits his lower forearm, within seconds, inflamed protruding blemishes appear all along the vein, all up his arm. Within 10 or 20 minutes, the "swelling" goes down and his arm looks normal again. Has anyone ever experienced this? Seen it? Know whats up with it? Cheers.
