Day 3 getting back to activity.

The last time I exercised was Monday. I have been trying off and on however it always leads me back to pain. Sunday I actually played basketball for the first time in over a year and it felt awesome I has right back to being where I always was with friends competing and using my natural gifts. I felt useful and young again as well as a sense of commodore. I felt free from my limitations that I had put on myself. However when I got home I started getting pain again and it scared me and I immediately started to second guess myself. I have to get my trust back. Should I just continue to push through or take it slow?
