"Diverticulitis & recurrent U.T.I."

In early Aug I felt unwell and in a lot of pain when going to the toilet which felt a lot like cystitis {suffered from chronic cystitis yrs ago} so on the Wednesday I went to the chemist and got Trimethoprim {3dy course} which only got worse over the weekend About a week later I had to get emergency app at surgery and was put on Nitrofurantoin {5dy course} which also didn't work and escalated along with a sharp pain in lower left abdomen So another emergency app was made for later that week which resulted in admittance to C.A.U  Crosshouse hospital for a scan which I didn't get, had intravenous Ciprofluxacin Friday night and sent home with {7dy course} on the Saturday  the doctor also mentioned Diverticulitis of which I knew nothing about.  finished the course of antibiotics and still felt unwell and went to A&E and was advised to go onto a high fibre diet given co-codamol for the pain {which makes me constipated} and again told it was Diverticulitis.

From then until mid September everything seemed to calm down to a bearable level I also had app with doctor that day and asked about Diverticulitis and how can they tell with just prodding your stomach.  The doctor went through my medical notes and found a letter which confirmed severe diverticulitis after a scope that I had in 2011 of which no one told me  the results of that procedure.   A couple of days after that I started to feel ill again with a U.T.I. had another app and got trimethoprim {7dy course] which gave me some pain relief then I started to feel unwell again.   I tried to flush my system but it didn't work and a week later I was back at surgery with symptoms of U.T.I. and severe pain in lower left hand side of abdomen and was put on Co-amoxiclav {7dy course} and again 17 days later I am  back at the surgery with severe pain when urinating.  Mid Oct I got Trimethoprim {7dy course} which again did not work and resulted in a tele consultation with doctor a week later and Ciprofluxacin {7dy course} that didn't work and resulted in another app and a 10dy course of cefalexin and Nitrofurantoin to take at night after my original course I have also asked to be referred to a urologist and dietician.   I have been off my work 3 times in 3 mths hence why I wanted a low dose of antibiotics to try and keep this infection bearable until I get to a urologist and hopefully prevent me from being ill and off work again .I am also getting support from O.H. at work.

So in the space of 3mths I have had 8 prescriptions of antibiotics sent away a lot of urine samples and blood and feel that I am  going round in circles and getting nowhere Can anyone tell me how long the waiting list is for a referral to urology and a dietician? I am now feeling  depressed and don't really want to leave the house in case I need the toilet and the pain gets that bad that people notice there is something wrong also I want to get back to work.

Can anyone advise me on what else I can do
