"No pain. No gain." is the credo of many sports people and their coaches, but it's not necessarily a healthy or safe one. You can cause an injury if you stretch beyond the point of pain. The same goes for holding a painful stretch.
The aim of regular proper stretching exercises is to improve your flexibility and making the muscles less tight and therefore less prone to injury. Regular stretching can also feel good and be a very relaxing part of your day.

* To help prevent injury it's important to focus on maintaining a good level of flexibility for your activity level.
* Different sports and activities use different muscle groups, so focus on stretching the muscle groups that you are most likely to use.
