Increased sensitivity or exaggerated feeling on one half or one side of the body.
From 'hemi-' (half) + 'hyper-' (over/increased) + Greek 'aisthesis' (sensation), a medical term for abnormally heightened sensory perception on one body side.
Someone with hemihyperesthesia might experience a light touch on their left arm as intensely painful while their right arm feels normal—it's the nervous system's 'volume dial' stuck on high for just one side.
