Lately I've Been Feeling Various Pain In My Left Arm.

Lately I've been feeling various pain in my left arm. Namely, right at the bend in my arm, the part of the arm right above the elbow. I've been experiencing various pin-pricks, sharp stabs, and dull aches of pain, which is doing TERRIBLE things to my anxiety about cardiac arrest. Despite these arm pains, I have no other symptoms of heart attack, no fast heart rate, no sudden nausea or feeling hot, no numbness, no SHOOTING pain... I don't understand what's wrong with me or why I'm feeling this specific pain in my arm.
