I'm a bit worried since I tested positive for COVID on May 17th but didn't have any symptoms except for a dry throat. I'm feeling better now, but since May 27th, I've been experiencing a mild burning sensation in my chest and some pain in my left shoulder and hand every now and then. I've been taking doxycycline and dolo 650 twice a day for 6 days, and ivermectin 12mg for 4 days. I've also been using vitamin tablets and adding spices like pepper, cloves, and cinnamon to my food for 9 days. My oxygen levels are around 98-99 and my pulse is 80. Apart from that, I don't have any other health issues. I'm also using pan d tablets, but I'm still feeling the burning in my chest. Could you please help me understand what's going on?
