I drink 2 sugar-free rockstars daily, and I have been for a few years, and I think it's messed with my kidneys really bad...I feel discomfort in my lower back, and I know it's not just muscle pain...I know I need to stop drinking the energy drinks, and I'm going to stop starting tonight, but I'm worried I may have caused permanent damage...I DID have a Scan done last year to see if my kidneys were damaged, and they said they were fine, and my bladder was just fine, but there was just a pebble-sized kidney stone, but one that wouldn't need to be treated...so I went on drinking the energy drinks, and now I'm worried I f-ed things up...
Your body is probably used to them and going cold turkey isn't a good idea. You should go to one a day for now and then once you get used to that only do it every other day, and wean yourself off of it.
Once you have gone a few weeks free of energy drinks, you should see if you feel a difference in your health. If your symptoms continue to persist, then you may want another scan. This can be a kidney issue or maybe something totally different.
