I am not sure if that is really kidney spasm, but it feels like kidneys are working much slower than they should work. The main problem is that I cannot urinate fully, because most of urine doesn't even get to bladder , it stays somewhere above.As a result, I am feeling pressure there, and I feel dizzy and weak. It's horrible, it feels somewhat like being drunk. It keeps getting worse or better, I don't know why. I have few very small kidney stones (which are, according to doctors, not worth attention) and I think they are the cause. I take nospa, but not sure if it helps. Any tips what should I do, or can it be dangerous? Sorry for my not perfect English.
