pubic lice (crabs) and body lice do not look like worms so i don't know what you saw or treated but if they are gone. this is good. based on what you have shared i don't think you will need any std tests or tests for parasites.
i think i had crabs but am not sexually active. the lice looked like a worm. lice free got rid of it. was it crabs? . i think i got this from a comforter i bought and used before washing or the homeless people who ride my bus. do i need parasite or std tests? where can i be tested? .
