PhoenixRunner,
It just so happens I've been suffering from interstitial cystitis as well and a quick search for MSM (DMSO2) revealed that this medication is used for these patients as well.
My calcification developed rather suddenly during an extended break from running so I think you might be on to something. Can I get MSM over the counter? And if I happen to be allergic to sulfa antiobiotic ( Bactrim, for example), is it safe to take? Not too many studies have been done on MSM and even DMSO has received a bad rating over the years for some reason.
My diet is better now and I take a multi-vitamin daily. Should I add more magnesium on top of this?
As for the shoes, what the last poster stated has me a little worried. I just received the ASICS 16 in the mail and was looking forward to racing in them but I don't want to take any chances. Is there another shoe, slightly lighter than the Nimbus, which would still be a safe bet for the half-marathon?
