I told you all I was taking some suspension in an earlier thread. I took a shot maybe 1.5 days ago in the left shoulder. It hurt about 3 hrs later. However I took a glute shot maybe 3 days ago and is still a bit sore. Anyways my left brachialis area is red. Also warm to the touch. I know people are gonna say its an infection. However the warmth is from the body increasing blood supply to the area. Also that is the reason it is red. I have no ball or knot. Just sore as hell. I massaged the hell out of it and it made it even more hot. Has anyone had anything like this happen??? I guess ill stick with glutes from now on. Any information on this let me know. Thanks.
