Ok so on Tuesday, so 2 days ago I injected 500mg/mL of Test cyp. I had pip the next day and then on Wednesday I had slight swelling, a little redness and some warmth in the area. Today it was an even bigger area of it on my upper outer thigh. After work I checked it out and pressed down on it with my finger and it left an indent for about 1-2 seconds then took its shape back. It's red, swollen, puffy, and hurts and now it's gotten bigger. It's about a 3x5 inch area of my thigh that is now swollen but it only hurts and majority of swelling is right where I injefted it. Is this an infection or just inflammation?
