I Have Had Three Bladder Infections Since August. The Last

I have had three bladder infections since August. The last two were only three weeks apart. The last one was dec 2 and I took 10 days of Levequin. I am still feeling sensation in the bladder. Years ago abou15 I had a cystoscope for the same problem of to many bladder infections. I mad an appointment with a urologist but it's not until January 8. It feels as if there is something in the bladder. It feels full. If this makes any sense. Sometimes after urination there will be a small amount of leakage after. No leakage when laughing or sneezing or any other time. What can I do to keep the infection away? I've tried homiopathic and pretty much everything on the Internet. I'm terrified of another infection. With in hours of symptoms there is visible blood and sever pain.
