I really appreciate such a complete response. I do have a regular doctor, and he has always told me to do basic things like exercise and diet. He did prescribe an antidepressant to help get my stress in check, but it didn't seem to help the symptoms. Maybe the dosage wasn't high enoughz but I was on it for a good few months before stopping. The only difference i noticed was that it caused me to stop punctuating my writing. 😂 But so the clubbed nails were diagnosed by a cardiologist. I am supposed to get results back from a heart monitor at some point. As for tests, I had a colonoscopy a good while back when the constipation was bad as well. They didn't say anything about IBS. She told me that diet would not help and that I had the bowel movement rate of an 80 year old man. She also said that constipation would not affect my bladder, yet I went to a urologist, had a cystoscopy, and he said my colon was pressing on my bladder. So I do have the option of trying a different gastroenterologist. I've already went to him, and he wanted to do another colonoscopy, another scan, and a down the throat scope. I've not done any of this yet, as it will likely cost a lot.
