I'm A 43 Yr Old Female Who's Never Had A

I'm a 43 yr old female who's never had a problem with blood pressure until the last month. Today it was 152/105. When do I worry? It used to run 98/65, that was my normal for years. Recently because of spinal chord compression I've been experiencing a lot of pain. My Dr said it's probably due to the pain and if the bottom number starts going over 90 on a regular basis I'll need blood pressure medicine. Any other suggestions?
