You need to tell us more before we can help. What kind of pool is it, volume, type of filter, size of pump. Also, we need some current water testing results taken with a drops-based kit. If you don't have a good kit, you need one. We recommend the Taylor K-2006 or 2006C from the test kit link in my signature below.
Supply us with the requested information, tell us what all you have put into your pool -- meaning ingredients and not just "shock" --- and somebody will help you go from there.
