I have fibromyalgia, being treated by neurologist, now bladder is achy and heavy (pressure) with pain?

I am a 38 year old female. I’ve had urinary sensitivity for many years, but rarely have had UTIs. Usually I take otc AZO and my irritating symptoms go away on their own. I’ve had symptoms over the last couple of weeks. AZO helps some with the pain, but not as well as usual. This doesn’t necessarily feel like the burning typical of UTI. My bladder is achy and heavy (pressure) with pain during urination that comes and goes. It is not going away as expected. Today, upon first urination, I found my urine to look completely strange. It almost looked like oil and water mixed, but that the “oil” on top of the water had a bunch of white stuff floating in it. I have also been peeing a lot lately (but very thirsty/drinking more, so may make sense?). I have low back/side pain (achy, with bouts of more severe shooting/stabbing feel). I also get that shooting/stabbing pain in my abdomen. This has happened in all quadrants, with the upper left and lower pelvis area being the most severe. My usual pain meds aren’t working as well as they usually do. I’m used to pain, but would like to lessen or eliminate as much of it as possible, of course. My aching pain varies in intensity from 4-7 and the shooting pains vary from 8-nearly 10, at times. I had similar symptoms a few months ago. Urine was tested and CT done. I believe all of that was normal at that time. Starting around then, and continuing today, I’ve also been quite nauseous and have watery diarrhea everyday. I have a referral to GI to look into this, but wanted to mention it in case it could be connected. And I have a swallow study this week because my esophagus spasms sometimes and I can’t complete my swallow or breathe in or out until that finishes. I do have fibromyalgia, so I try not to go to the doctor unless a symptom is way more severe or completely out of the norm or new for me. I have been having way more health issues over the last 1 1/2 years, beginning with gallbladder removal (stones) and complete hysterectomy for pain and severe bleeding. I also have PCOS. I’ve been to the doctor quite a bit and am not sure what to do. When I go in and they don’t find anything conclusive, if they test at all, they often assume it’s related to fibromyalgia or nothing at all. I am also currently working with a neurologist for severe short-term memory loss, confusion, missing time, changes in senses, increased muscle weakness and neuropathy testing. I’m sorry for all of the back story, but I thought it may be important. I don’t know what to do right now for my bladder(?) problem, or any of the problems really. Go to the doctor again or wait it out??? What could be causing all this? Thank you!
