simply because you have cancer doesn't give you a free reign to distort my point about pain. There are two ways that some people respond here..."exception proves the rule"...and "my condition proves the rule". 2 for 2.

Read Salvifici Dolores to better understand the proper Christian understanding of pain, which is at great variance from your view. 

There is a spectrum of pain & Church teaching accommodates all points in the spectrum beautifully.  None of my points depart from this teaching. 

Some forms of "ordinary pain" (getting up, common colds, twisted ankles,  applying exactitude to finish a job well, sore necks, stiff backs, tingly fingers from stenosis, etc.) are perfect examples where a Christian can brace up a bit, & draw closer to union with Jesus in that moment of pain.    Offering the little pain for reparation, in thanksgiving, etc.

It takes a bit of practice; but the intimacy with Christ is dear. 

More extraordinary pain can be managed with prudent use of pallitatives
