Hello, You also have UTI infection. You are hurting your clitoris by using vibrator too frequently or too roughly for a prolonged period of time. If your private area is dry, you should use lubricants before using vibrator. Do not share your vibrator & use it when it is clean. You are suggested to avoid sex or any sexual activity for a couple of days till you are being treated. Give yourself time to heal. Be gentle with yourself. Take care of your hygiene, clean your private area with antibacterial soap and water. Apply Miconazole cream or Soframycin cream on the affected area. If the purple color is not going, then you can apply ointment Thrombomycin, it will help the blood clots beneath the skin to disperse. Pain-relieving medicines can help reduce swelling, inflammation and any pain. Continue antibiotics for UTI. Complete the course and then get a repeat Urine Analysis done to confirm that there is no more infection. Take care. Hope I have answered your question. Let me know if I can assist you further.
