You have to be investigated for arteriosclerosis vascular disease
for light headed and pricking pains. Smoking
is one of the reason for this. But alone stop smoking is not a cure. You have to get a proper treatment.
Palpitations is a heart related issue and smoking is one of the major cause. It can be PSVT
or AF. You may need beta-blockers or calcium channel blockers to control this. Consult your cardiologist for both the problems.
