I am a 29 yr old female. I had anal sex 4 days ago. It was very dry and he ended up tearing me a little. It didn t hurt much. He ended up lubricating both our parts with his saliva. At the time he had a large cold sore on his mouth, that kept opening whenever he ate. The next day I had itching and irritaion on my anus. The next day this was accompanied by nasuea and headache. Now i have bumps around and in my anus, a fever, headache, nausea, chills, and my bum hurts so much I can barely move, sit, or lay on my back. Do I most likely have herpes now?

Hello Miss, Welcome to Chat Doctor. I have gone through your query and I understand your concern. The possibility that you may be infected with Herpes Simplex Virus (HSV) is very high. You also mentioned that you had also a little fissure on your anus, and it could also be the site of entering various bacteria and infect you. In order to give a definite diagnosis, you have to visit your local physician, who may order cultures (blood, tissue, and fluid samples) of the sores and send them to a laboratory for examination. Your doctor can typically diagnose a herpes infection by a visual examination of the herpes sores. Although they are not always necessary, your doctor may confirm his or her diagnosis through a laboratory test. Genital herpes is not the only condition that can produce these symptoms. Sometimes, HSV is mistaken for vaginal yeast infections, bacterial infections, or bladder infections. The only way to know whether they are the result of HSV or another condition is to be checked by a health care provider. Hope I answered your question. If you have other question, don't hesitate to ask again. Take Care,
