I am 37 and 180 lbs , one year ago had total hysterectomy and could have lost my kidney but had stents placed to save them. I have them about and my kidneys are recovering slowly. My question is my knees are aching tremendously, I have a different aching feeling in my stomache after urinating, and I am very fatigued with insomnia and weight gain, I also swell very much. Are all these symptoms normal a year after my surgery.
