The Nature and Purpose of Pain?

[wes_misener]

Leo just wondering your insights on the purpose and nature of pain? Pain really confuses me at times of how present and how much it can actually fluctuate on a daily basis. Then there are different types of pain, emotional, physical, what is called good pain and supposed bad pain. I find I do things to avoid pain but also at time I do things that cause myself pain. The key question someone would say is just to be with your pain and accept it but paradoxically why can things hurt so bad and the experience be so uncomfortable. 

I am sure its not an easy question to ask but I only want to ask your insights on the topic.

thanks,
