What Causes Pain In Chest While Sneezing When Diagnosed With High BP?

I have a very hurtful pain in my chest (in heart area) when I sneeze. No cold or allergy, no heavy lifting no pain in my arms. within the last week I am slightly noticing some discomfort in that same heart region while resting. I m in pretty good health (no medications) other than I guess I have arthitus pretty bad in all my joints. I don t take vitamins(they plug me up big time), I am a moderate drinker. 61 years old. I have no insurance, have had a physical for work 1 year ago. Have borderline hi blood pressure. ^ ft, 230lbs. My arms always ache es[pecially shoulders even when sleeping. I do not have any idea of family history other than my Gma died @ 55 from heart attack although very small and thin.
