My sister told me about a home remedy for k stones. She said put a tablespoon of lemon juice and a tablespoon of malt vinegar in a glass and fill it with water.
I have been doing that once each month for years and have not had a k stone attack since.
I have had 4 attacks before she told me about the remedy. I hope it helps, KiC.
Of course you have to drink the mixture. LOL
