Many say what? Pain keeps us from placing our hand into the hot flame of the stove, warns you that you have an injury and do not do more damage. Stop and repair it. Pain also has a mental component.
My pain has become much easier to live with because I bring it out and exert effort and power over it. I actually go for hard walks where my pain escalates until I want to stop. That is the time when I kick in my music, willpower and legs to move and walk for another 20 minutes. I use no pain killers now. I was taking eight plus a day. I live my life and some things cause pain but they are worth the hassle. You can gain more power over your pain in many ways.
