I have this pain in my left kidney.. it feels like someone is squeezing then letting go squeezing and letting go but when I sit its bearable. The pain is also going toward my lower back. What do you think this could be. I am a 28 year old Male.

I will need about 10 ccs of blood and about 20 ccs of urine to give you even an educated guess. Since I can't do that over the Internet, you will have to visit your doctor to rule out kidney stones.

Ok thank you, I figured I would try on here because I have no Insurance but thank you for your time!
