So I have recently started doing quad injections along with my delt/glute injections to rotate more areas for rest/scar tissue purposes. This is my second time injecting into my quads. I went upper, outer. About halfway point between my knee and hip. After my first time doing so, I had some immense pain, specifically in my right quad, which I figured was do to virgin muscle. Just before the next round of quad shot, everything was at 100% again (roughly 5 days later). This time around, both legs hurt which I suspected was because it is still a newer muscle group I have started doing this in. However, this time I have some swelling on both quads, and some redness showing at both injection sites. It’s only slightly warm, not at all hot at the injection sites. This was 2.5 says ago that these injections happened. I did check my temperature, and it was 99.9, however I’m also currently sick so I don’t know if the slightly elevated temp is due to my cold or due to the injection. Yesterday at work, my upper legs to the top of my knees was definitely somewhat swollen. It hurts to try and squat, walk around etc. it is significantly better, I have been taking hot showers and lightly nassaging the area, and have kept my legs elevated when off of my feet. I also did leg day immediately after the injection, as I have done even with the first time I injected quads. Any idea if I should be worried?
