I suddenly developed pain in the area of my left back shoulder blade, but interior, not like a bruise. When I bend down, it's much worse. If I hold up my arm, it feels better. Earlier, there was some discomfort under the arm. My left hip has been bothering me for a few days, as well. I'm generally healthy, have no chronic conditions, slight hypertension controlled by a low dose of Quinapril, and am also taking 10 mg of Pravachol. Just completed a course of Amoxycillin in connection with oral surgery. Any ideas of a possible cause for the pain? If it persists, I will go to my primary physician this week.
