I injected test prop and tren ace in my quad 2 ml total on Tuesday and since yesterday It started to hurt me and its like a baseball the thing that i am sure of is that its not an infection as I dont feel sick or whatsoever but I am wondering what caused this and how can I treat it PS usually my injection sites start to hurt me 6 hours post my injection and slowly starts to subside after 2 days but this time it started to hurt me two days post injection and its swollen
