Hi,
This is most probably UTI, maybe 
urethritis. 
Urinary tract infections are a common bacterial infection in women and the risk increases with age. Women suffer more frequently from recurrent UTI than men because of their shorter 
urethra and proximity of urethral opening to the anus. Other predisposing factors in old age include 
diabetes, urinary tract stones, steroid use, and chronic illness impairing the immune system. 
Advice 
1.     Ciprofloxacin
2.     Syrup alkaline citrate
3.     Drink plenty of water to flush out bacteria
4.     Drink cranberry juice 
5.     Do not hold your urine. Urinate when you feel 
6.     Wipe from front to back after bowel movements
7.     Urinate after having sex to flush bacteria
8.     Investigation – routine examination of urine, culture & sensitivity of urine
Hope I have answered your query. Let me know if I can assist you further.

Dr. Ivan R. Rommstein,
