I feel i may have some sort of parasite. my symptoms are loss of appetite, feeling bloated, vomiting, and my anus itches. any recommendations?

Could be, could not be. No way of telling without examination of anus and stool. Primary care doc usually better equipped than Urgent Care or ER.

Stool studies for ova and parasites following an exam and detailed history should answer your question. Seeing your doc will ensure that work up continues in case a parasite infection is ruled out.

If you have not travelled out the US, you are highly unlikely to have any worms, other than Pin worm. You doctor can diagnose that treat it with a pill, if needed. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines.
