@Sarah060486 - I do as well. It can radiate into my hips on bad days. If you haven’t yet, talk with your urologist/PCP.
Isolating the cause for me is hard as it appears to be a delayed reaction. Too much stress one day can lead to pain several days later, but all the intervening stuff can add to it too. Under hydrating is immediate though. Some sources I’ve found for me are food related, muscle (lower back, pelvic) tightness, or high stress.
Stretching and yoga can help. Heating pads on neck and abdomen. Quiet time with a lot of nsaids and cbd help.
