My Urethra I Believe Is Hurting Even With Cranberry Pills.

My urethra I believe is hurting even with cranberry pills. I eat healthy and I always drink water. I have kidney stones. And I have been having a pain in my right side as if the last 4mm stone is still there but not moving. Other issues and not sure if all connected but last two months tingling in my heels and my left big toe... Ha.. Funny weird. I guess m old. Can anyone help me?
