Just a random health question

So I've been into ballbusting (sadly only been able to do solo) for as long as I can remember, but about a year back I had a kidney stone and it made my nuts hurt. Intentional nut pain is fine (can even be fun) but unintentional like kidney stone pressure sucked, the question is mainly for the guys who get busted fairly often... Do you ever worry that the pain in your crotch is not just residual and is actually health related, or is there some way to tell a difference? (Kidney stone is just a personal example, there could be others)
