I still don't understand how you pin your quad without it locking up on you the next day. I did it once just for the ease of it and was so thrilled until the following day. Probably not what the OP wants to hear but everyone is different. We all have areas that work well and others that suck.
Did you pin the area where your hands would be if in your pockets? That's the sweet spot and it also depends on how much and how fast you pinned... remember the compound is basically taking up free space therefore providing outward pressure until it is absorbed. Solvents come into play as well as concentration of said compound. Injecting along with vitamin B can ease discomfort as well. I used to be what you might consider a PIP fiend as I sought out higher concentrations like candy... I've pinned 800mg of test in a single 2cc pin before and although days later the PIP was not very comfortable it was bearable and knowing I had such a beast in a bottle made me feel better about it all.
