I was having fever 5 days ago...the fever lasted for 2 days along with nausea and weakness and headache..I didn't had any other signs apart from this..no sore throat and no cold or cough so I didn't do my covid test.. besides I was feeling all fine from the past 2 days..but now I have slight headache on one side and slight jaw discomfort or very very mild pain on the same side...is it the early signs for Black fungus.. should I get checked ?? I have very mild headache and very mild discomfort of jaw but wanted to be sure...
