Hi, Thanks for posting in HCM. I understand your concern. Redness and swelling of inner labia what you are experiencing after using sex toy could be due to local reaction in the form of mechanical pressure or allergy to the materials used in the toy. Kindly do the following to overcome it. 1. Wash the area with cold water and mild antiseptic solution like Savlon twice daily. 2. Following drying, apply Hydrocortisone skin cream over the lesions. 3. Take Tablet. Levocetirizine once a day. 4. Apply moisturizer cream or lotion over the region at bedtime. 4. Wear loose fitting undergarments to provide good ventilation and to avoid friction. 5. Abstain from sexual activities till the symptoms subside completely. Maintain good personal hygiene. The symptoms should heal gradually and should be back to normal. Hope the information provided would be helpful. All the best.
