Sorry about my typo, it appears you read my first "can" as the intended "can't".
Good, you have been checked by a cardiologist. I don't recall what it is that Nitro does to relieve pains related to the heart, but if prescribed by your doctor it must be the right thing to do for some relief. Has your cardiologist given a diagnosis/name on your condition?
Given your heart checks out fine, it may be you need to discuss with other medical expertise, have you discussed with your primary (family/general) doctor?
Thank you for the response I have seen a cardiologist I have had an ECO and a stress test done so far the stress test has shown I do have a good flow of blood and good muscle tone in my heart which is some relief the biggest time of day I get the pains into my jaw is at night depends on what I did that day is how sever the pains can be during the day time The Nitro at least does good at relieving the pains I am always very active and I enjoy doing the things I do so this is getting a bit old very fast
I can be of any specific help to any of the symptoms, but I can say I think you should discuss with a doctor. The list of symptoms need to be check "hands-on" by a medical doctor.
