I believe there is, generally speaking, two kinds of pain:
1. Sharp pain.
2. Aching pain.
1 means stop what causes that pain and find out what's wrong. 2 means the name of the day probably has a y in it and you need to man up and move on.
Barely a day goes by where I don't have some 2 pain going on. Luckily 1 is quite rare
