I Have Experienced Several Uti Infections And A Kidney Infection

I have experienced several uti infections and a kidney infection which resulted in septicimia and having to go to a and e to be treated. This has been ongoing since September 2015
I now have pains in my legs and am finding it difficult to urinate, I am also constipated. I rang 111 yesterday and they recommended that I went to a and e. They diagnosed another uti, I have only been free of antibiotics for approx 3 weeks. I slept really well last night, but my legs are painful tonight and I can't get to sleep. I have drunk about 2 litres of water, but probably only passed about half a litre. My kiddies feel like they are awash.
I have an appointment with my go tomorrow morning to discuss an ultrasound I had on my bladder and kidneys. I would like to get these symptoms sorted out as it is nothing I have ever experienced before.
Email YYYY@YYYY many thanks
