Sick and miserable! What can I do?

Been sick for over a week with the worst cough I have ever had as well as sore throat and sinus issues. I have been drinking decaf hot tea and breathing in steam. Nothing gives me relief, and of course, I can’t take any meds. Any other recommendations to ease some of these symptoms? This is the worst I have been sick in years. I have already tried to get in to see the doctor for swab tests.
