Kidney/side Pain, no diagnosis

Hi, I have never been diagnosed with a kidney disorder-no kidney stones, no abnormal tests, nothing.

For the past year I have had kidney/side pain, sometimes drinking water becomes hard(I get bloated and nauseas, full-on just a little water), sometimes I have to pee a lot and sometimes I don't have to at all. Usually when I get bloated I don't have to pee, when I do still feel bloated after. When the bloating begins to decrease I have to pee a lot, but I will still have this side/kidney pain.

Last year my naturopath said I probably have a minor UTI, he gave me an herbal mix to take. It helped out, but didn't clear it up. Right after this I went to my chronic disease specialist for Lyme disease and after that my pain went away. I would still get it on occasion.
Nothing turned up on bloodwork during this time, neither the chronic disease doctor or ND suspected kidney stones.

In a few weeks I go back to my chronic disease doctor, I get my blood drawn the second week of August.

In the meantime, does this sound familiar to anyone out there with experience?
This is something that comes and goes for me. I used the herbal mix again and was doing good until today, and it came back just as strong. But the pain never 100% disapeared.

It's a bruise type pain, with some aching. Never sharp.

Right now it feels like I've been punched in the back on my left and right side.

Thank you!
