My VVS is triggered by colon cramps or spasms which leads to excessive sweating, nausea, fainting etc. There is no relief until colon has emptied, so no way you can lay down & put your feet up until it passes. Just hope you don't fall off the commode. I'm just wondering if anyone else has this & what helps the symptoms? I haven't asked this question in awhile so hope by now there is a magic pill I haven't heard about. Thanks.
