Thank you for your answer !
I e -mailed the lab results to my family dr. last night and he also answered that the cold and sinusitis could have caused the high CRP, but also if there is any arthritis in the body, and said if I want to we can do the high sensitivity CRP. I'm borderline for lupus for 2.5 years and I have according to a sinus CT ( I had it for a problem after a tooth extraction last year ) a chronic sinusitis. The last time ( 2 years before this one ) I had a CRP test it was 2.2 ( 0.0-4.9 ). I know it can change any time.
