Hi and welcome to HCM.Thanks for the query.
all this indicates some infection in your body and most usually this is urinary or respiratory infections so these are first things to rule out. I odnt htink these marks are related to your febrility and it requires dermatologic work up. So do tests to rule out those 2 infections. if nothing is found and fever
persists,you should visit docto to do more detailed work up.
Wish you good health. Feel free to ask. Regards
