Yes, it s normal. If you become addictive about taking your pressure, you will find it spikes and jumps throughout the day. Personally, I wish my mom hadn t bought one of those things. She takes her pressure many times a day, constantly worried about the numbers, and sharing the pressures with me and asking what I think. I tell her to put the damn thing away, take your pressure once in the morn, and again in the eve, if you notice a pattern, then call the doc. Another thing to note about this, all monitors are not created equal, your monitor may show you have elevated digits, but when you go to the doc, it s not, or vice verca. Slightly elevated for short amounts of time is normal.
