I gave my shot in my thigh a few days ago and it made a swishy noise when rubbed. like there was a pocket of fluid under there. It's gone now. But I was just wondering because I didn't use the autoject. I did it manually but why would it do that? I didn't have the needle in too short. Maybe it went under the muscle or can it make that noise in the muscle? I dunno, and it was weird.
