(this is my first post i apologize in advance)
I have polycystic kidney disease amongst other things as well as UC and because of my kidneys i am heat intolerant, always need it very cold 70F max really. However, if i get very hot and i turn on a fan or something of the sort and it blows cold air on my stomach or if my stomach gets cold in any way it's excruciating! Heat on my stomach however is very soothing. I'm on a massive dose of oxycontin(80mg3X/day and oxycodone30mg4X/day) for my kidney disease but i've been on it for so many years that it's not really doing much for my kidney pain or UC anymore either. It was such a godsend when i started getting pain management for my kidneys and i only had to deal with UC pain typically before i took my pain meds for the day. I would stop taking the oxy now since it's not really helping my kidneys much but mostly i'm afraid of the fullblown UC again... i've never had an issue with addiction, i do know that at this point my body accepts it as normal and i would go through withdrawal D which would make it much worse than normal so... anyway that's my experience with heat and cold
