I note from your profile that you had pneumothorax in the past and had undergone surgery for the same.
What was the cause of this pneumothorax?. What kind of surgery was done? Any part of the lung was removed?. Had the lung fully expanded following the surgery?. These details are very pertinent in your case assessment.
The symptoms that you mention can be attributed to a number of illnesses including the ones you suspect.But,a meaningful conclusion can be arrived at, only after thoroughly examining and investigating you.
Again i would like to point out to you the importance of the thoracic surgery that you had gone through. Disorders leading to hypercarbia(increased partial pressure of CO2 in the blood) +/- hypoxia(low oxygen tension in the blood) are capable of manifesting the symptoms that you allude to.
The serial changes in the blood counts that you have mentioned do not seem to be very significant, but will be certainly co-related with the overall picture.
I urge you to consult your thoracic surgeon who, will be better placed to assess you and sort out these symptoms.
