My CRP were 20 on May 25 and 38 on June 1 and 19 on June 7. I discharged from hospital on June 7. I am in home rest till now. Yesterday I took blood test. The CRP increased to 39.  Current symptoms:  1. still I have white mucus in my lungs and I am trying to cough out as much as possible. 2. Body temperature found 99.5 degree Fahrenheit. 3. Chills. 4. Tiredness and fatigue. 5. Difficulty sleeping.  Sir, it would be really grateful if you are able to answer me below question. 1. Why my CRP value is elevated? 2. is it because of white mucus present in my lungs or because of virus multiplication. 3. 38 days gone since my first symptom. virus still present?
