Kidney Stones :: Feeling Continuously Sick - Normal?

I was told on September 1st of this year I have a kidney stone. (Started at 6.4mm and went up to 7mm) since being diagnosed, I've suffered regularly with cramping sensations in my lower abdomen and have been feeling sick almost daily, to the point where I easily throw up and usually can't eat much. I've lost around 2st in the last 3 months because of it. I had lithotripsy yesterday to break it down and when I woke up this morning, I was constantly feeling sick from the time my eyes opened until I was loaded up with morphine, the pain was absurd as well. I couldn't sit but when I stood up, I wanted to throw up, which happened a lot today on an empty stomach. I ended up in emergency and was sent home a few hours later with oxycodene. The first two times I went to emerg after being diagnosed was owing to a painful cramping sensation in my lower abdomen and ongoing sickness. I was told twice 'it could be a bladder infection' and was given anti biotics both times. Turns out I didn't have an infection but they never look any further and just blame my symptoms on the stone. Both times my stone was in the exact same place (very top in my kidney), my stone was diagnosed as non obstructive. Since September I've been passing blood almost daily, am mostly sick and experience cramping feelings weekly if not daily. I've been to the doctors and emerg so many times and they just said it was the stone without any investigation.. Has anyone else experienced any of this? If my symptoms persist after the stone fragments have passed, they said they will investigate further.
