Hello dear I understand your concern Burning sensation could be due to contact dermatitis/chemical burn, atrophic vaginits/estrogen deficinecy, vaginal infection. Haemorrhoids can not cause burning sensation. I would suggest to consult the gynecologist and undergo vaginal examination,swab test and urine tests to confirm the disease.Treatment will depend on the cause. Meanwhile take following advises: Apply vagisil cream Wash vagina with warm salted water and then apply apple cidar vinegar Put lactobacillus suppository Wear pure cotton loose inner Maintain proper pelvic hygiene by using V vaginal plus wash. Avoid perfumed cosmetics and soap. Drink plenty of water and take healthy diet. Hope this may help you Best regards Dr. SAGAR
