Hi troops! So I got a P8 for a one off episode of a Kidney stone back in 2016. It was a microscopic one and got CT Scanned. The Doctor said it was due to lack of fluids and i’ve never had it before or ever since. Been advised to get a letter from my GP to say I'm fine and a up to date CT Scan to prove I'm in order. Whats everyones views on this case? Thanks!
