I quit smoking cigarettes 6 months ago and like 6 weeks ago i started smoking cigars now for the last 2 weeks i have had a sharp pain in my head only when i cough it doesn't always happen but at least 80% any ideas?

Stop smoking: Congratulations on stopping smoking cigarettes. Unfortunately, smoking cigars has the same hazards as smoking cigarettes- see http://www.Quitsmokingsupport.Com/cigars.Htm. I strongly urge you to stop smoking cigars. The pain in your head when you cough suggests inflammation. If you don't cough you won't have pain & stopping smoking should reduce coughing, if the cough & pain persists see a doctor.
