Hello. Im a doctor, and I used to work at a covid center in Akaki Addis Ababa Univ. Whatever we give to the patients is a painkiller, panadol every 6 hours, even when they have no pain. Then Get Vitamin C and D supplements from a pharmacy close to you. Ginger, Garlic and Orange are also useful. Eat well...sleep and exercise. Thats it. Stay well.
