THE LAST FEW DAYS MY BLOOD PRESSURE HAS BEEN ERRATIC ESPECIALLY THE DIASTOLIC WITH A HIGH AROUND 100. AVERAGE 134-100. NEVER REALLY HAD A PROBLEM WITH BLOOD PRESSURE.THE BLOOD VESSELS (I THINK) IN MY NECK FEEL LIKE THEY ARE GOING TO EXPLODE, BUT IM NOT SURE IF ITS THE VESSELS OR NERVES. IVE HAD A PRETTY STEADY HEADACHE. AT TIMES IT FEELS LIKE NEEDLES STICKING IN MY NECK. WHAT MIGHT BE THE PROBLEM BASED ON THESE SYMPTOMS.
