I just discussed this with my doc. Every few months I start to feel like I'm getting a bladder infection. Our immune systems are depressed from RSD, afterall. I drink 100% cranberry with no sugar (from Trader Joes) added to sparkling water for a few days, and it always clears up for me.
If you haven't had your blood sugar checked recently, that is something important to have done as well. My mom claimed she was having bladder issues due to her age (self diagnosis) but it turned out it was Diabetes. Since her blood sugar is back in control, the problem has gone away.
Double check All your meds for possible side effects as well. One I took years ago, caused me major accident prone problems.
And none of my docs connected it to the med at the time since it was a rare side effect.
