I Woke Up On Friday And I Had Strong Pain

I woke up on Friday and I had strong pain in my kidneys, I drank like 4 glasses of water but the pain was still there. I vomited some time later and started to feel better, I told mom im okay now and there is no need to go to the hospital ,I fell asleep but as soon as I woke up I started to feel the pain again. And I was hungry as well so I had some home made mango milk shake and just as I was about to go to the hospital I started feeling better again. But in the end i had to go to the hospital and they checked my urine, blood and took an X-ray but all the results were normal and they said it is just muscular pain.They gave me a pain killing injection.
Saturday was normal almost no pain at all. But today I started to feel the pain again.
Ive been visiting the dentist quite often this week for dental problems too and I also have a fractured right wrist and I sometimes feel the pain in my stomach too.
