How To Manage Heightened Sensitivity To Odours, Nausea And Mild Dizziness?

Hi, I was hospitalized for dengue fever the other week. My symptoms were fever, intense headache for a week (I was not able to stand up at the end of the week), dizziness, and vomiting. I've recovered since, but afterwards I've noticed that I've had a heightened sensitivity to odors, nausea, and mild dizziness that gets triggered very easily. These never manifested in me before I had dengue. Any advice on this and how I can manage it? It's begun to interfere with my work. Thank you.
