** Thanks for contacting with your health concern 1. Sex is a common cause of UTI in women because sexual intercourse introduces bacteria into a woman s urinary tract [because their urethra is much shorter than the male] and thus more at risk of bladder infection. PS. UTI has been nicknamed honeymoon cystitis because frequent intercourse often leads to the development of a UTI. 2. As the symptoms are recurrent so one has to exclude risk factors for complicated urinary tract infections. [as might be the case for you], which may impede urine flow like congenital urinary tract abnormalities and inflammation. PS. According to the rule of thumb: Frequency of sexual intercourse is the strongest predictor of recurrent urinary tract infections in patients presenting with recurrent dysuria. 3. according to the Journal of American Family Physician: Patients at risk of complicated urinary tract infections are best managed with -broad-spectrum antibiotics initially, - urine culture to guide subsequent therapy, and - renal imaging studies if structural abnormalities are suspected. 4. Other predisposing factors which can be considered are any immunosuppression, diabetes, chronic kidney disease [CKD], being in a nursing home or hospital. 5. Patients with recurrent UTIs should be counseled about risk factors such as spermicide use, frequent sexual intercourse, and new sex partners, as well as about preventive measures, like i. Cranberrry juice has shown benefits in women with recurrent UTI [daily intake of 150 - 750 ml] ii. Several studies have demonstrated the effectiveness of using topical estrogen (0.5 mg of estriol vaginal cream nightly for two weeks, then twice weekly for eight months), but adverse effects are common. PS. Clinger 3 [clotrimazole] is used in gynecological infection and one route of administration is as pessary and rash, pruritus, pain, vaginitis are documented side effects of the drug [which you are experiencing], so consult your doctor again since the medication only works for vaginal fungal infection and you might have a different type of infection [like bacterial vaginosis] for which different medication may be needed.
