My blood pressure fluncuates between extreamly low to extreamly high as does my pulse. What is a safe normal fluncuating number I know 120/80 is ideal?

Varies. Older a person is, and the more risk factors for stroke and heart disease, the more dangerous fluctuations could be. Normal to have large fluctuations during exercise, extreme anxiety/stress. If at rest, something may be wrong. Heart rhythm testing, checking for medical conditions that could cause this- hyperthyroidism, adrenal problems- is needed. BP can feel like it is fluctuating and be normal.
