Hello doc, when am experiencing body pains and fever I have done with RT PCR covid test, test result is negative. And I also done diabetic profile everything is normal. I also checked my blood pressure it is normal. Am feeling light headedness and weakness. Many health centers are saying that RT PCR tests are negative now a days even though there is presence of virus. They said We need to do HR CT for further evaluation. Am not experiencing fever, cold and body pains but weakness and light headedness. My question is this due to covid or anything else ??? Whether I need to HR CT for further evaluation??? Is Xray enough rather than HR CT for primary evaluation??? Please help...
