Do symptoms of sore throat, radiating pain, and a burning sensation in the hands and legs after unprotected sex suggest HIV?

Hello,

My girlfriend and I had unprotected sex about two months ago. After that day, I was worried about HIV (Human Immunodeficiency Virus). After one week of exposure, I got a burning sensation in my hand, leg, feet, and toe that radiated from one hand to another. After two weeks, I got a sore throat. I went to a doctor, and he saw my throat and said it looked like a throat allergy. He asked me to wash it with warm water and salt. After four weeks, I got rashes on my arms which were eliminated when I took allergy medicine. The biggest problem is my thigh pain which radiates toward the groin and gives me groin pain and moves to the hip. Also, pain in my hand is common. There is no swelling, but a burning sensation on the hands and legs goes for some time and comes back. After two months of exposure, we tested for an HIV antibody test, and both of us came negative. Tell me, are these the symptoms of HIV or not? Which diseases can cause these symptoms? Please answer in detail.
