question: I have a twitching sensation occurring in my back on the right side near my right kidney. It feels exactly like being kicked by a 24 week foetus. I am not pregnant. The sensation has been persisting for about a month now. It is not painful but definitely notable. I have had blood tests in the last month which were all fine apart from cholesterol of 6.6 which I have been addressing with diet. My fathers brothers (uncles) have had kidney stones, renal failure and I have had an ultrasound in the past for PCK which is fine (8 years ago). What course of action would you recommend. Should I be concerned.
