The rule with blood clots is if you get them more than once, you go on Xaralta or something like it for the rest of your life. I had one incident in my right leg, and the other in my chest. I thought I was a deadman when I got the one in the chest.
I have had kidney stones for around 10-12 times. The pain is simple. Imagine someone taking your balls and put them in a vice and then just keep cranking it down and down and you are screaming your guts out depending on shape and where it is stuck. If you have to have surgery, they go straight into the hole of your dick, and then they leave a stent in you to open up the urethra so you can piss out the stones, The other type of getting rid of them is when they take a machine, put it next to your side and waves come out and beat the shit out of your side and then if small enough you can start pissing them out. That stent makes it feel like you are pissing glass. Pray it only stays in one week, cause sometimes it is two. When it is time to get the stent out, there is a wire like thing where they grab it and rip it out. You will piss blood for about a week after and it will fucking hurt.
