I am having attacks which increasing my heart beat rate without changing rthym and sudden increase in blood pressure something like 130-110 also i am shaking during this attacks. doctors here unable to put diagnosis any opinion?

Raised heart rate: I am not sure what 130-110 blood pressure means, Is if 130/110? In general, if you are 23 their little chance that you have a serious condition based on your age. If you doctors have done testing and found nothing it could be you have anxiety. I think of hypoglycemia, gastric dumping syndrome There are rare conditions like pheochromocytoma but that is about 1-3 per million chance.
