I am experiencing pain in my chest and back with a developing sore throat. i would like to confirm its not corona. ?

Unclear question: Talk to your doctor about getting a test for the virus. If needs a throat swab and molecular testing. A person of your age, without underlying illness is at low risk of getting sick with Coronavirus.

South Africa policy?: I am not sure what the testing policies in South Africa. Consider a telemedicine evaluation with your provider. The majority of doctors viewing your questions are located in USA. Our policies/ protocols may differ from yours. 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.
