Hello sir/mam, i'm feeling ill from 1 week now, i took milk powder, and it gave me diarrhoea and thats when this problem started, my body temperature is very much normal, only once or twice it raises in a day, my doctor asked me to do get some tests done, which were - cbc, thyroid profile, lipid profile, blood sugar, lft, kft, and urine r/m, report of all came fine, my body is getting very weak, feeling feverish and having chills sometimes, my covid is also negative, And also i want to tell you same kind of problem i had in last year also, and i took me around 3 months to recover, that also happened all of a sudden
