I just had a kidney stone removed and now have a stent in place, should I return to the hospital/ER the pain is so bad in my side down to my testicals, and blood in my urine is pretty thick though I am drinking a good amount of water. Should I be concerned about the amount of blood and its thickness and cloting and the pain. I am unable to sleep and the norco isn't helping with the pain. The stones were removed on Friday and it is now Sunday
