At 77 age treated for bladder cancer, 28 radiations and 5 chemo. Now after a year no trace of it in bladder but perhaps catheter related uti since then is still not cured after twice culture tests and suitable antibiotics given. Burning feeling at urinating is still present. Now a days I find palpitations and high pulse rate may be due to uti. Guide me please. Age 78 diabetic plus bp for 30 years.
