Where did it come from?

Someone asked if I know why I have a kidney stone. I don't know, but I have a theory.

Since I had my herniated disc, I have had periods with a lot of cramps in my leg. I have now resigned myself to this to a large extent and I think that it is a result of the nerves having been trapped by the disc bulge. The problem seems to be slowly going away and the cramps are a lot less frequent since I am not really cycling any more.

However, at some point I was not consuming any dairy in my diet and was having a lot of cramps. I experimented with taking a calcium supplement often a couple in the middle of the night when I was awake with cramp. It didn't help so I stopped, but not before I had an initial blood in urine experience last autumn which first alerted me the kidney stone problem.

Now I have done some more reading on the subject, it seems that there is a correlation between calcium supplementation and kidney stones. I hope very much that this is what caused the problem because it is then within my powers to get rid of it. I already drink quite a lot of water and the rate of recurrence of kidney stones is rather high unless there is a specific cause that I can eliminate.

I've stopped the calcium supplements and I am not taking any vitamin D at the moment because I am able to get some sunshine now that it is summer. I may start it again next winter if necessary otherwise I don't plan on taking any vitamin supplements at all for the time being.

For the record, it hasn't come out yet.
