In general - kidney stones are a terrible thing to have. They are built-up calcium deposits which eventually turn to 'stones'.
I have had kidney stones 3 times. I will share the order of 2 of those experiences with you in the order which they happened.
Experience 1 -
I had a little back pain in my kidney area for an hour or two... not too unbearable. I drank a lot of fluid thinking that maybe I was going to have a kidney stone (my dad had them in the past so I was familiar with them). The pain subsided. I spent that same night in a hotel with my girlfriend. The next morning I felt the urge to pee in the shower so I figured what the hell... as my urine began to stream out as usual - I felt an instant shooting pain in my dick so I held on to one of the shower rods very tightly and continued to pee. About 6 seconds in to the piss I all of the sudden felt relief from nowhere - not less than a 1/4th second later - I see and hear a pretty good sized stone hit the bottom of the bathtub. It was dark and I literally heard it 'ching' against the tub of the shower. All pain was now gone. End of kidney stone.
Experience 2 -
I was working at my desktop computer when all of the sudden I started to get gradually worsened pains in my stomach/back/kidney... it felt like someone was slowly but continually squeezing a belt around my body tighter and tighter. I drank a ton of water hoping to ease the pain like I did the last time I had a kidney stone. Pain lightened up for awhile and this continued on a less-painful scale for another 2 days or so until one minute when I got very severe. I had to walk away from my pc and lay down on my bed. I held my side, used a heating pad, took pain pills (leftover Vicodin), etc... and the pain seemed to be getting worse............................
Long story semi-short - I went to the hospital that night. They put me on fluids and asked if I had been peeing any blood (took a pee sample). I had blood in my urine and I was not laying in the hospital...... they took me back for 2 CT Scans - bla bla bla. They found what appeared to the doctor to be a kidney stone.
For the next 3 days I had a lesser amount of pain than before (luckily) -- and I eventually peed parts of the stone out little by little (lucky once again) into a strainer. I peed into one of them for about a week to see if it was gone. The damn thing broke into little pieces on its own... not very common.
Normally the doctor would need to laser it down if its too large to pass on its own... through your tiny piss hole. That would be a painful process for the fact they first stick a camera inside of your piss hole......... etc. etc.

I wish you luck on your journey.
If you are peeing blood - please make sure to ask your doctor for an antibiotic to clear up the infection.
Drink less tea, etc.
The doctor told me I should have had more water or beer and it might all have passed sooner than it did.
