Hi today as I was walking to the gym I felt a pain on my last two toes and, after I removed some hangers that were on the gym's parking lot and felt a pinch, there were also small metal objects, after getting home from the gym I checked my shoes and didn't show signs of scratches or a puncture and checked my sock and didn't have a trace of blood so i would like to have your expert opinion on this, would there be an hiv exposure
