Hi Thank you for asking HCM I have gone through your query. Your problem is most likely urethritis. It can be due to urinary infection. A urine routine test should be done to rule out that. If that is clear it can be due to irritation from chemicals like soap you use to wash the area or detergent used for cloths. Avoid soaps and irritants to wash the genital area and instead you can use warm water or saline. Hypoallergic soaps like cetaphil can be used. Using intimate wash also will be helpful. Hard detergents should be avoided for washing undergarments. If urinary infection is there then if you were my patient i would recommend antibiotic therapy and urinary spasmolytic like flavoxate. Hope this may help you. Let me know if anything not clear. Thanks.
