Angina
When blood vessels towards the heart decrease in surface area, blood flow is restricted[1]. This leads to a pain in the chest area known as Angina[2]. The NHS say that "the pain and discomfort of angina feels like a dull, heavy or tight pain in the chest that can sometimes spread to the left arm, neck, jaw or back"[3].
