I have a bad headache with nausea. my blood pressure,which had been normal,is high 140/90. i've been having panic attacks as well. should i be concern?

Of course: After all, whose body is it? Only you know the details of this circumstance - but if this is lasting longer than a normal un-well period, see your doctor for an eval. It may be a relatively simple matter to get back on track. So check it out! Best!

See your PCP: Any headache must be viewed as a valid medical disorder and the headache assessment must be comprehensive. See your PCP for evaluation, tests and treatment options.
