I had a kidney cyst removed 4 years ago. Recently I have a gurgling popping sound in that area especially after a meal. When sleeping I get pain if I lay on my left side. I can feel something under thye left rib that makes the spongy noise when pressed. I think my cyst has refilled or regrown.
I have had that for maybe 3-5 months now.. What's weird is maybe last year I had this ache on my left side at the bottom of my ribs. Is was so bad at times I could even get out of the car. Then my doctor gave me steroid which I took for 2 months and that aching went away. Only wen I'm slouched over if stretched out my side aches. Then I got the bubble feeling. At first it was only were I had my aching on my side.. Now it's on my right and left side! It feels like a bubble and hurts, it's a sharp pain and I can sometimes "hit" we're it hurts and it pops. When it pops it hurts and when I have it I can take a deep breathe and it will hurt a lot but will pop then leave my side a little sore for 7-10 seconds. I nor my pedeatrition knows what it is, I have had blood work, screenings, tests... Still nothing.. Glad to see other people have the same feeling. Keep in mind, I'm 12 and having this so it worries me. Especially sense Im having/have CRONIC pain for a year and a half at 12!!!!
