I was so addicted to kheeni, but I knew I had to stop because I am only 24, I had the habit for nearly 2 years, constant right after I eat lunch, dinner or snacks, as soon as I stopped taking tobacco within an hour my head was so heavy, then slowly I got fever, and now it keeps on coming in cycles but I have not touched tobacco. My question is, Is it possible that I have acquired cancer virus or is it just the withdrawal of tobacco doing this to me. If so how long will it take? When I checked the symptoms of mouth cancer I was shocked to see fever and headaches. Please help me here.
