GERD/ Hiatal hernia. Upset and feverish.

I am suffering from GERD issues from last 3.5 months and it has caused real panic and anxiety issues also. Initially started with left abdomen pain then to right abdomen which at times shifts to chest and back. Consulted Drs online and started medications. Last month I could go and visit Gastroenterologist who suggested USG and UGI endoscopy and diagnosed GERD with hiatal hernea. Got USG done all normal but scared to get endoscopy in this scenario. Even after taking allopathy medicine for 3 months couldn't get much relief so switched to ayurvedic medicines (Chandrprabha, trifla and kosthamrut) as suggested by store representative from last 10 days. Things were getting resolved but from day before yesterday had lose motion and then started feeling feverish wher as body temperature is 96-98 F. This episode has again started anxiety and panic issues. Not able to make out what's going on in my body. Should I go and get tested for COVID 19. At present feeling stomach upset and  feverish.
