Two weeks ago i touched a random object on the bus. I don't know if it was a syringe or needle inside the jacket. I'm scared i may have caught hiv. The next day my lymph nodes on my neck got swollen and my sore was irritated. 3 days later the other side of my neck got swollen. I don't know if my body is playing games with me because then i started experiencing some sort of annoyance on my knees. I've been experiencing night sweats on my neck and fatigue. Today i started coughing but it is dry. I'm scared that i have hiv, i'm only 17 years old.
