My blood pressure is 165/92. should i be concerned?

Yes: This is definitely high blood pressure. You should get evaluated & on meds. Even if you feel fine, this level of hypertension, if confirmed, can cause long term damage to your system.

Agree with Dr. F: It is not an emergency but needs to be addressed. If you are overweight, losing weight would be helpful. You may also need medication. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Wish you good health!
