Are there any natural ways to check to see if i have high blood pressure if i don't have any machines, cuffs, or equipment at home?

You go to a big box store like Sam's/Walmart where they have automated kiosks available to test this. There is no substitute for equipment use.

None. There is only one way to check whether you have high blood pressure. The blood pressure should be checked several times on different days to be certain that anxiety in the office is not causing your blood pressure to rise. The recommendation is to have you relaxed in the office for several minutes, avoid conversation, and be at rest before the blood pressure is checked.
