short of breath and intense heartbeat

Greetings. For almost a year I've had some unusual symptoms involving a constant pressure feeling in my head, along with the feeling of muscle weakness or stiffness in my forehead. Due to this, I've been pursuing neurological explanations with a headache specialist and another neurologist I saw.

However, the thing that makes me wonder is it something else is because there are times when my heart will beat intensely for about 10-50 beats and during this time I feel a sharp pulsating pain near the upper part of my chest where the shoulder bones meet your neck (this is a throbbing pain along with my heartbeat) and I also feel the SAME PRESSURE in my head pulsate much more intensly along with my heartbeat. Usually, the headache is dull and boring, but when the pulsations happen I also hear the "bruit" sound in my ears alot. The thing that triggers this is often standing up too fast, or BLOWING UP A BALOON. I have also experienced nausea that comes and goes, and feelings of shortness of breath while at rest, which improves upon exercise. Horizontal vertigo has also been a problem.

I have had an ABG, chest xray, Echo, EKG, MRI and MRA of the brain and cervical-vessels, and Pulmonary function testing. Everything negative.

Should I have some additional testing done in your opinion..such as an MRA study or CT scan of my chest?

I also forgot to mention that things like sneezing or coughing hard gives me a few seconds of relief. Also is it normal to be completely out of breath on your first cough?
