Yes, different alters can have different physical reactions, symptoms, tolerances, and abilities. One part may be more sensitive to pain, noise, light, touch, hunger, fatigue, temperature, or medication than another. Different parts may have different headaches, vision changes, posture, handwriting, energy levels, or stress responses. Some parts may become nauseated, shaky, dissociated, frozen, or emotionally flooded more easily than others. Other parts may feel stronger, more alert, more emotionally numb, or better able to function under stress.
In dissociative systems, the body is shared, but different parts may experience the body differently. Some parts may hold physical memories, pain, tension, or trauma responses that other parts do not feel as strongly. Different parts may also respond differently to medical procedures, therapy, medication, exercise, or sensory experiences.
This page is part of the Somatic and body-based symptoms in DID section of the CommuniDID site, which explains why dissociation can affect the body, including pain, sensory changes, or neurological-like symptoms, even when medical tests are normal.
