I have had bladder changes since covid. I don't have an infection. I'm a nurse, had many as a child, and know those symptoms. No burning. I do have to go when I have to go with some resultant leakage.

Here's the thing, I've had long COVID for 2.5 years. I have CRPS which spread from COVID. I ended up on Prednisone for the last two months and everything that was a problem since COVID, went away with such a strong anti-inflammatory. I know am sure it's all from inflammation everywhere which is what long COVID is. Inflammation that won't go away and can (and does for some of us) affect everywhere in the body. About to go on a to inflammatory diet. Should have done it long ago but haven't had the energy to eat healthy food for a while. Living alone, it's usually a quick sandwich. Inflammation. Look at all your symptoms post COVID and see what you can relate to inflammation. If you had it before and it's worse post COVID, it's not your age suddenly. It's post COVID.
