I had my appendix removed this august. since then i have daily right flank pain that gets pretty bad at times. I do have a history of kidney stones but i do not feel like these are the pain. it used to happen once every couple weeks or so but now it is daily.it starts in my right flank, sometimes travels to the top of my groin area but then the pain goes back up into my kidney area. i have no problem urinating, it does not hurt when i do so. The pain will go away if i lay perfectly still in bed for an hour or so but sometimes comes back if i get up. I drink a bottle of water when i get up in the AM and this seems to trigger the pain for the day. it doesn t matter how fast or slow i drink it, it hurts within minutes. The pain the past week has been towards the front of my side, not my stomach and not my back but right in between.If i get up in the AM and have no pain, it can start if i am up and walking around for more than about an hour, sometimes shorter.Very confused on what this could be. I am afraid it is something wrong with my kidney.Any suggestions?
