Well since this was posted nearly 15 hours ago, if you are still ok then get to your doctor ASAP.
Remember, hypertension takes many years of consistent damage to cause cardiovascular problems. My cardiologist assured me that the human body is very resilient, although even a resilient, healthy human can take high BP for so long.
So make sure that your blood pressure is being treated properly. There are many causes for chest pain, not all of them associated with cardiovascular issues. I get chest pain caused by anxiety and panic, but all Echos and EKG's have shown my heart to be in perfect health.
That being said, you need to get to your doctor so that he/she can diagnose you properly. Only then will you know what is causing the chest pain.
Remember, hypertension is treatable and is a condition with which you can live a normal lifespan as long as you keep your blood pressure under control.
