From November 22, 2007 to January 22, 2008 I maintained a detailed record of my urine pH correlated with my pain levels and what foods I ate. Every time I urinated I noted the time, my urine pH as measured with test paper, and my pain level, where 0 = no pain, 1 = no pain but sensation (tingling), 2 = mild pain, 3 = moderate pain and 4 = severe pain. I had one sheet for each day where I also recorded what foods I ate.
I continued to maintain periodic written records through to May of 2008, and after that I checked my urine pH periodically with no written record for about another year.
0 = no pain, 1 = no pain but sensation (tingling), 2 = mild pain, 3 = moderate pain and 4 = severe pain
As an experiment, in August 2008 we deliberately lowered my husband’s urinary pH through diet. Although he does not have urethral syndrome / non-specific urethritis, on the ninth day of the acid-forming diet, he experienced burning pain in the urethra. See chart at left.
My findings were clear and consistent. Acid urine is the immediate cause of my pain.
