When I did the kidney/bladder cleanse my kidneys ached terribly for days. Usually one side more than another, you will find that one side of your body will be more dominate with parasites than the other, mine is my left side, more aching and feeling them moving around. I use to put warm packs on my left kidney and would be rubbing that area all the time. Well the good news is the cleanse helped me, I use to get kidney infections all the time and I haven't had one now for over a year and counting.
I never noticed worms with this cleanse but that is because I wasn't looking then, didn't want to see anything!!!!
Try putting a heating pad over your kidney area and see if it helps and drink water inbetween the cleansing drink to flush the toxins and parasites out as soon as possible. My father died of bladder cancer, bet I could have saved him, but didn't know all of this then--sad--
The spaced out feeling, I have had this often also, still do sometimes, hang in there, it is all worth it...heyjude
