You mentioned that your clotting time was normal, that is a good sign because normally
PV is the result of the thick blood that occurs with
PV. This thickness slows the flow of oxygen-rich blood to all parts of your body. Without enough oxygen, many parts of your body won't work normally.
If you don't have any of the abnormal symptoms and the doctor isn't concerned, then try not to worry, however, if it continues to upset you, then maybe get a second opinion.
