I'm highly pain tolerant so when I experience something painful, it's something excruciating.
3 weeks ago, I was visiting a friends house for the week for a convention. Well I was taking a shower and out of nowhere this pain shoots down my back and intensifies in my lowerback, it instantly made me collapse in the shower and made me cry. I managed to get up to exit the shower only to dry heave in the sink. The pain remained at maximum intensity for about 10 minutes, and it slowly dissipated throughout the day. I don't know exactly what it was, but I think it was a huge kidney stone passing, as I have had kidney stones in the past and this pain was similar to the minor discomfort I use to have from them, but on a magnified scale
