I know this is an old post but I am currently being treated for c diff 2 days left on dificid with persistent symptoms after going undiagnosed for 9 months. I also have Candida esophagitis. All of my issues started with the “stitch” in my left side. It’s right between my two lowest ribs and feels like stabbing and twisting of my insides. It was intermittent weekly for years before and is now daily at a level 7-9. Does this sound similar to your pain in your side and did it ever go away? Did you find anything to help it? TIA
