question: I had a lithotripsy on Monday afternoon to busy a 7mm kidney stone. It is now Thursday night and for the most of today I have been experiencing a painful tingling sensation in my urethra (though it could technically be in the lower portion of the bladder)... It feels like little pins are being stuck into my urethra all up and down the tube, and every once in awhile it will be one long string of pain up my urethra tube. Any idea what this could be?
