Ever since childhood, whenever the weather was supremely hot or I didn't get as much water as I would like, I would get immensely painful spasms around where my kidneys are. Before I go into any more detail, I'd like to state that I was previously told this could be due to
kidney stones, but that's now looking like it's not the case. The pain only lasts a minute, but as of lately I've noticed it happening even when I was well hydrated, but exhausted/overworked.
