Hey Dr. Actually I had sex with a prostitute about 1 month 20 days ago. I used a condom and I am sure that the condom was not leak or have hole anywhere. But think too much about my health. Is it possible to get HIV even after using a condom. And what are the main and most common symptoms of HIV. Are they come together or individually. I have a mild sore throat after 4 weeks of sex and small pain in bone pain. And I have vitamin b12 and vit d3 deficiency too. Is pain is due to vit b12 and d3 deficiency or I might got infected with hiv ? In too much stress . I don't have other symptoms like fever, headache , or other flu like symptoms . Just have a mild sore throat and little pain in bone. And do not have problem swallowing and chewing.
