I am a 21 year old female, I have had unprotected sex with 4 people in 5 years. A couple months ago I started experiencing symptoms that could be of HIV. For example, I was itching all over my body. I washed my comforter and sheets and that helped that symptom. I've had what seems to be canker sores. I've changed my toothpaste from Crest to Sensodyne and haven't had one since. Recently I had to go to the eye doctor and found out my right eye had cornea abrasions and and ulcer. The doctor gave me Zymar, a bacteria antibiotic and that cleared that up. If I had a viral infection such as HIV would the bacterial antibiotic have treated my eye? Also, I've been working at a mail processing place for over a year. Throughout the day I work with a lot of cash, checks, and rubberbands. I've been getting rashes on my arms but I've noticed when I'm home I don't get these rashes. I only get them at work. Do you think I'm at high risk for HIV? And do these symptoms have anything to do with HIV?
