Hi Thank you for asking HCM. I have gone through your query. Sores can be due to irritation from razor. Avoid soaps and irritants to wash the genital area and instead you can use saline or warm water. Applying betadine ointment locally will be helpful. UTI will clear up with antibotic. You can use potassium citrate in water to relieve the burning sensation. Taking cranberry juice or barley water will be helpful also. If there is no improvement then urine culture and sensitivity test should be done and change antibiotic if necessary after getting culture report. Hope this may help you. Let me know if anything not clear. Thanks.
