i would watch it carefully because it's red and it's been so long since that particular injection. you might consider having your dr check it out.

i too have lumps that last after injections. i've been injecting 9 yrs and some sites i can't use anymore. i used to use my autoject a lot and switched to manual because of that problem. manual has improved my problems a lot.

try some ice packs on the site. i've had 2 times where i've stopped my injections for 2 wks to let my body settle down. (don't do this without your dr's approval). it helped.

i also just set up an appt for an RN to come out and re educate me on the shots. i wonder if that might help you too.
