What are the main physical symptoms of a blocked Heart Chakra?

A blocked Anahata Chakra can manifest physically through chest tightness or pressure, chronic upper back pain between the shoulder blades (as muscles contract to protect the heart), shallow breathing or restricted lung capacity, respiratory conditions including asthma, and cardiac irregularities in more severe cases. The arms and hands — the physical organs of the Anahata through which we give and receive — may feel heavy, cold, or weak. Immune dysregulation is also associated with heart chakra blockage, reflecting the well-documented connection between emotional state and immune function.
