dude,believe you me I KNOW....i had a 1 week bout with the 'stones(my obsession with pepsi,no less.....24pack gone in 2 days....dark cola is bad for hereditary stone development).pain hit me in back,around kidneys first,and then moved into my groin(OUCH!).felt like the best soccer team in the world was kickin' me over and over in the groin!went to the e/r on 1st and 2nd 'bout and my crying out in pain made the nurse takin'my vitals cry also(God bless her!)morphine and fenegrin didn't help.the nurse asked to describe my pain on a scale from 1 to 10(i LIED,stating it was only 5)she then said"Tears don't come from the 5 scale...."so,she said i know what will help.she brought in a needle the size of Texas(which frightened the hell out of me!)...and thankfully put into i.v.she said"this should help the pain".my first experience of Deltoted.WHOA!my skin went hot,then......absolutely NO PAIN!i couldn't feel my eyelids!....so,after a dye solution i had to drink(higher than i kite)and an MRI,they discovered 5 stones in my right kidney and 1 in my bladder.Doc said 1 of the stones in my kidney was about 5.2mm(about a 1/4 inch...YIKES!)Caffine stones was the diagnosis,and,i should stay off the cola which i have for 5yrs now.Now,this is what i have done since:I drink 2 to 3 beers an evening(doc says will help in flushin' kidney's)also,apparently,the hops in beer somehow help to dissolve existing stones(no proven medical fact),and that the frequent urination helps to flush the system.so far(knock on wood)i have had no re-occurrence of this EXTREMELY PAINFULL experience.i hope no-one else will EVER have to go through what we here have discussed!
ps:2 emergency visits=$3,400 dollars! VULCHERS!....there goes my credit score!shot down like a winchestered a/c with a whole lotta fully loaded,angry birds on his/her six!
