This is Dr. David
I am sorry you are having these symptoms.
severe anxiety or anxiety attacks can cause spike up in your bp and and cause headaches as well.
abdominal bloating can be due to your diet, sodas, poor diet, sensitivity to gluten in bread, carbs, lactose sugar in milk or dairy.
also spikes up in blood pressure can be due to pain, hormone imbalances, high blood cortisol levels, thyroid problems.
you need to be checked for diabetes if you are very thirsty and also get blood test to check your cortisol levels, kidney function
you need heart testing of echocardiogram, EKG and stress testing to see if something is wrong with your heart which can cause spikes up in blood pressure.
so you need more testing to be sure what is going on.
is your doctor running more tests for you?
