I'm really worried because my oxygen level has been fluctuating between 88 and 90 for the past three days. I'm 52 years old and weigh 95 kg, and my blood test came back normal. However, my CRP level was 35 mgL on April 13 and then went down to 8.60 mgL by April 27. What should I do about this situation?
there might be chronic obstructive pulmonary disease,kindly refer to a pulmonologist
