Heres the deal, my last test-c quad injection, I got a horrible pain 6 inches below my injection point one day later, it has hurt for the last 3 days and my entire quad is red and itchey, this happened once before on my right quad but it never got red and itchy, just sore. Im usin 22g- 1.5 inch, this is my tenth shot so far, and the only time its happened. Also, I only go about 75% of the way in with the 1.5 inch. I use the useual method, alcohol swab the area, and the vial, use one needle to draw, and the smaller one to inject. Is this maybe nerve endings?
