Hi I'm having another episode of anxiety. as I was walking down my street I felt pressure on my foot. My mind started thinking what if it was an used needle with HIV fluid on it. I checked my foot once I got home and can't see anything because I have dry skin on my foot. I wear vans. Also, I walked past a bush and got scraped. I started to think what if a needle was in the bush and it scraped me. I looked at my arm didn't see anything but its hard to tell since I have scars/marks on my arms. If there were needles with HIV fluid with both situations am I at risk? Should I get tested. I'm really worried.
