So this is a weird situation but a friend of an unknown HIV status squeezed my cheek quite hard and her fingernail somehow scratched part of my mouth from the inside. Since she bites her nails, there might have been blood on them that could've come in contact with the cut she made on my mouth. Two weeks post this I developed joint and muscle aches all over my body, and diarhea (although only once, than the stool was back to normal). Do you think I should take a HIV test or I'm just being paranoid as usual when it comes to the disease? Thank you.
