Last summer, I became aware that all was not well with my insides. The GP was putting me on laxatives, but I knew there was something serious going on and asked for a colonoscopy. I was told there was a long waiting list. I paid £80 to see a private GP, but was told that a private colonoscopy wouldn't be available for another week.
(Eventually, having been put on the 2-week pathway for an appointment with a consultant, I was told on day 9 that I would be telephoned by a consultant on day 14. By day 12 I was I so much pain that I went to A and E, was scanned and had an emergency operation the next morning, a right hemicolectomy.
In this case, I think both GPs, NHS and private, should have sent me to hospital tow weeks earlier. But hindsight is a,wonderful thing.
