Kidney Stones was it for me, I went months on months avoiding the doctor, not sleeping at night with really bad pains in my lower back hip region, the only way I could get comfortable was standing. Riding down the road in my beer delivery truck was the worst by the end of my route each day I was damn near standing up in my truck driving. Wife finally talked me into going to the doctor after I pissed straight blood for a couple days. Sure enough, doctor came in and said son do you play golf, I replied every once in a while, he said well than your familiar with the size of a golf ball. I had a slightly smaller than a golf ball size stone lodged in my urine tract. This was when I was fishing night tournaments 4 days a week so I lived on monster energy, he determined it was that and I naturally produce a lot of protein in my body so those two mixed caused it.
I had to have the shockwave treatment done to bust it up, talking about sore it was almost as bad as the stones themselves. My entire back from my shoulders to my waist line was bruised black and blue, I couldn't move best I could do was move from the bed to the couch. For a week straight I passed enough sand to fill up 2 baby food jars, the next week I passed 14 stones absolutely the worst pain in my life. Needless to say no more Monster for me. It has been about 6 years and haven't had one since.
