Yes, it is a little unfair to belittle what can be a severe and distressing condition for many people.
I guess comments like
The backache is growing pains & the rest is just "a virus" (doctor speak for "I can't be a*sed, where's my golf clubs?")
tend to start you off on the wrong footing.
The posters misinformed-I should rise above it, I do in "real" life.
