So after my first pin in each quad I never had PIP issues again. Here I am on pin #13 and 2 days after I pinned my left quad I get what I think is some crazy sore PIP. ( 1ml test cyp / 200mg) But my quad feels pretty swollen, not very noticeable in the mirror thank god, but it's definitely slightly bigger. The pain feels like a deep bruise and it is an inch or two below the injection site. Last night my quad was warm to the touch also. I use alcohol on the vial, another on the leg. I let the alcohol dry. I use fresh and sterile pins from the package. Draw and pin with different needles. Only difference was that I finished a vial so I used maybe 1/10th extra of a ML this pin. Nothing significant at all. I checked my temp last night...98.6, no fever and I felt fine. Pinned Thursday morning, it's now Tuesday. Any thoughts?
