I'm really worried because I had protected sex a week ago, but after four days, I started feeling unwell with fever and loose motions. Now I'm also experiencing night sweats. I ended up in the hospital, and all my tests came back fine, but I read somewhere that these can be initial symptoms of HIV. This really has me scared. Could you help me understand if I should be concerned about HIV or if there's something else going on?

It's important not to jump to conclusions without proper testing and evaluation. The symptoms you mentioned can be caused by various conditions and may not necessarily indicate HIV infection. If you are worried about HIV, the best course of action would be to get tested for HIV at a healthcare facility. In the meantime, if you are experiencing fever and loose motions, you can take over-the-counter medications like Paracetamol for fever (500mg to 1000mg every 4-6 hours as needed) and Loperamide for loose motions (2mg after the first loose stool, then 1mg after each subsequent loose stool, but do not exceed 16mg in a day) to help manage your symptoms. Make sure to stay hydrated and get plenty of rest.
