I have a horrible feeling that I passed a kidney stone yesterday 
I have had a mild UTI for about 10 days which I thought would clear up itself but gave up and got some antibiotics from the docs yesterday (too late I suspect).
Yesterday afternoon, I suddenly had the WORST pain in my lower back, stomach, side (basically the whole low left-hand side of my body). It also got worse in one area and then that would ease off and the pain would move to another area. I was also sick a couple of times (but not nauseous).
Eventually, the pain eased off after about 4 hours and I was left with a dull ache in my lower left back which I still have this morning.
I have had gallstones and I would say the pain was on a par with that.
Should I have gone to hospital (I didn't as DH was away and I had the DC by myself)?
Assuming it is that, do I need to do anything now? Will the ache in my left side disappear? How do I know when it has come out in my urine?
