I am a black female, 30 years old, 5 2 at 149lbs. For about 30 mins I have been experiencing dull, sharp pain right under my collar bone. It seems that is it traveling to my back, shoulder blade area. When I got to stretch my arm out forward, it feels tighter. When I extend my arm outward to the side, it is uncomfortable. My resting heart rate right now is 86. I have had a few elevated blood pressure readings 135/93 for example. My overall health is good. I work out 4 times a week. My diet is horrible though.
