20 Weeks with Tremfya: Read the Instructions! (4th Injection)

On Sunday evening I took the fourth Tremfya (guselkumab) injection out of the refrigerator. As I carefully opened the box the instructions fell out onto the desk. I thought, hey, I know how to inject a syringe subcutaneously, so I don't need to look at it. But a seed of doubt entered my mind: have I really injected Tremfya correctly?
