Sound in my throat, dry mouth. Curable?

Covid diagnosed on July 29. Today Day 24. I still have mild cold, at times headache, knee pain and at times mild breathlessness and with weakness on and off.. My oxygen saturation is normal. Now, I have my stomach growling and my throat making sound with mild pain in my chest.. all reports normal like ecg, esr, cbp, chest X ray, whole abdomen scan.. I sleep and wake up with utter dry mouth in the morning.. I do not snore most of the times and I did last night.. I feel burning sensation in my throat.. doc has given Pan L, Pan 40 and Providac for a week.. I never had acidity problem earlier.. will it keep recurring and is not curable? Note: I was on high dose Vit D3 alone and antibiotics taken were Azithromycin (3), dolo 650(5) and levocet(5) I feel well one day and feel low on energy another day with mild breathlessness..
