did a delt inj in what I can say (as a non dr) was what I believe to be the right spot, 1 inch needle all the way in. same as I had in left arm.
yesterday I notice a red mark about two inches long slightly raised that starts about three inches directly below inj site at the sort of " juncture" of delts and where they insert near bi/tri... it seems to go down along line muscles about two inches at most... isn't really warm, hurts not much more than any other bad pip, but the redness and slight swelling worry me...I have no fever either.... any thoughts?? thanks
