Suggest Cure For Persistent Throat And Neck Pains Followed By Headaches

Have been having throat/neck pains down left plus headaches that come and also feeling tired, has been going on for about a year now. have been to doctor twice, first said it was a gland infection second said it might be stress. have been worried because it is ongoing. I do smoke but not alot probably about 20 to 30 a week also drink most weekends.
