Hello, Welcome to Healthcaremagic. Thanks for your query. I have gone through your query and understand your concern. I suspect you may have Genital herpes. The features you are having like blisters, rashes and itching are typically genital herpes symptoms. It is one of the sexually transmitted disease. It does not necessarily mean to transfer by sex. It may be transmitted by use of infected individuals soap and scents etc.. There is no permanent cure for genital herpes. But the symptoms can be lessened and prevented with treatment. Treatment can also reduce the risk of passing the virus on to someone else. Usual treatment for Genital herpes is Antivirals like Acyclovir. Your Primary care physician may know about the dosage and drugs. My advise is to get proper physical examination by dermatologist. If possible , consider about swab test for further diagnosis. Hope this helps. Please reply for further queries. Wishing you good health. Regards, Dr.Manjeth kumar.
