hello. Sir/mam. I am having back pain since a year. But I have kept on ignoring it until last 2 months back. I visited a doctor. And I was evn on medication. Today after few tests he told me that I am suffering from polycythemia. I wanted to know what kind of risks are related to this. And also does smoking weed and cigrate affects this. Because my parents do not know that I smoke. I'll be very thankful if you let my doubts get cleared. I I aM deeply tensed.
