I am urging any one who suffers with severe cystitis, to check with their doctor that it is not Interstitial cystitis.I have just been diagnosed with interstitial cystitis. After suffering for years with cystitis.After years of agony and every antibiotic on the market a consultant told me he rarely gets women sent to him,like myself I went with a prolapse bladder to be told I also had this other condition which attacks the lining of your bladder, unfortunately at present there is no cure. Only just come home from hospital will keep you up dated with the outcome of it
