So the problem started in November last year, I had fever, viral infection but I was a smoker so even in viral infection, I didn't stop smoking but after that viral infection, whenever I smoke I felt something awkward like numbness. This awkwardness went down after some time but then again after smoking it start again. In last 6 days I only smoked 2 cigarettes but still it feels but compare to previous days when I smoked a lot (around 10 cigarettes) less numbness. I started smoking in April 2015. Kindly suggest me what it is, I want to get rid of this feeling.
