Dear Doctor, I am 46 years old and diabetic. Having E coli in urine analysis with burning while urination, After that levofloxacin have been used and recovered. Now after few days I am having same problem with burning urination. Is any problem to participate in intercourse with wife. It will be attackable to sex partner also. Kindly suggest me how to cure this e coli? Is there any precautionary diet required? With thanks.
