for the past 2 years i have had a headache not bad all the time but it never seems to go away. sometimes it gets really bad and puts me on my tush. here lately i have also experienced numbness in my left leg after i exercise and the headache always gets worse with serious dizzyness where i cant drive sometimes. can anyone give me a hint as to what might be going on so the doctors may be able to stop phishing for a problem that they dont know what it is
