Hello, My mom is 58 yrs old. She is suffering from Rheumatoid arthritis. She had her vaccine 10days ago. She started getting fever since yesterday. So we got her blood tests done. Pls find attached blood reports. Kindly advise, what does this high CRP level means. Is it dangerous? 20 days ago, her CRP was 12, and 4 months ago it was 45. 105 is so high, is it life threating?? Pls advice.. She did not went out after vaccine, but since her temp was 100.4, we made her do rt-pcr test. Report is negative. But she is recently getting fever frequently, which goes off on its own ( most of times without medicines).
