Hello dear Understand your concern tingling sensation and itching in vagina after urination suggests lower urinary tract infections (cystitis, urethritis). I advice you to consult the gynecologist and undergo urine routine, microscopic and culture to confirm the urinary tract infections. Vaginal swab test should be done to exclude vaginal infection. Doctor will give following advice: Tablet septran plus nitrozolium, tablet pyridium and syrup cital do not delay in empty the bladder and empty the bladder completely. Maintain pelvic hygiene before and after urination and sex. Wash vagina with warm salted water. Wear pure cotton loose inner wear Drink plenty of water and juice of cranberry and orange. So pregnancy doses not cause tingling sensation and itching. Hope this may help you Contact HCM for further health issue Best regards Dr. Sagar
