Hi, i have been under stress the last few days, but today, i feel tired. dizziness / thickness in the head. earlier in the morning felt as if the upper back, just below the neck stays cold. worried that i may have corona virus-worsening my feelings.

Hard to say: early viral disease, and mild viral disease can have mild symptoms. your area does not have a lot of it. http://www.workingmemory.space/coronavirus.html click on the maps

Consider: Consider telemedicine consult with your doctor since COVID 19 can present quite variably. I refer you to “https://sacoronavirus.co.za/” which is the COVID 19 South African Corona Virus Resource Portal for guidance specific to your area.
