Kinda at first, I had a progressing ache in my back around the kidney area; moved around, stretched...basically like you said, but nothing bad enough that I thought I was going to have problems with kidney stones.
But like bigboybanshee said:
To the T, I woke up & didn't know what to think other than "OH MY F'N GOD!" Never felt no shizzo like that before; I knew something was fubar...didn't want to go to the ER, so I ate 3 loratab 10's I had, chewed one up so it'd hit me quicker & swallowed the others...then went to sleep, kept popping pills every time I woke up to stay asleep until I could get into the doc the next day...then after some Xrays & a CT scan they gave me some more pain killers & told me to go home & hope they come out on their own. My doctor told me the pain is equivilent to a woman giving birth to a child; I thought "oh gee, how lucky am I " And he was right I guess, hurt like nothing I could ever imagine...but hopefully it's all over now.
