5 week ago i had sex with a female, she was menstrating. I had a split condum on entry about one inch. The following day i had an accident and two weeks later i experienced dizziness, tireness, headaches, pins and needles in the feet and stiffness in the neck. My neck still pains today. I have difficulity moving my neck around. I had little difficulty swollowing and I have not noticed any swollen nodes. I also experience low back pain. The pain has also transfered to my upper back and i experience burning in the chest. There were other people in the vehicle at the time of the accident; they have no symptoms of whiplash. I am confused and afraid. Have I contracted hiv?
