Diagnosed with AS last year after 10 years of pain.
I developed blood in the urine, both visible and microscopic, in January 2019 with no other symptoms. I was sent to a urologist. Urologist ordered a Cat-Scan, which revealed small kidney stones and a small kidney cyst. She also performed a cystography, which proved negative for bladder issues.
I never felt excruciating pain I've heard people with kidney stones have. And, I'm still bleeding four months later. My rheumatologist says it's not the Humira. I'm next being sent to a gastroenterologist/nephrologist because that Cat-Scan revealed a hidden mass/neoplasm on my duodenum.
Meanwhile, no one knows if the bleeding is caused by kidney stones, which apparently are not being passed, or some other random reason.
