Welcome RileyNH,
Take the deep breath and be aware that most of these are beatable and treatable! Going to a URO was a good move and the progression of tests is very logical and normal. My PCP tested for an infection first after passing gross (visible) blood (hematuria) and that is about the biggest difference in our comparison. That sent me to the URO promptly. Urination issues alone often will not always send someone to a URO.....although I think it is still good idea for anyone else reading our threads as bladder cancer does not always present with blood. CT scan with cystoscopy are the "gold standard" for protocols and a second TURB is done when the first reveals high tumors or other indicators. So, you appear to be in good hands. Waiting about 6 weeks is also about right to let you heal from the first and is good medicine to confirm things. Along those lines, some opt for a second opinion for fresh eyes and peace of mind. Drinking lots of water is always good.
Your other symptoms? By all means let your Doc know about those. The CT scan should have ruled out other issues. I know after I was diagnosed every pain or creak I was asking myself is there more. My brain was in overdrive. That went on for 6-8 months. Keep posting as you go as someone here will have some insight. Read about about BCG and other immunotherapies as that is the normal protocol for high grade, non invasive tumors. Last item, if the URO hasn't warned you, your area that was burned/cut should pass a clot 10-17 days post. I did and would have freaked out had I not been warned.
