Causalgia, also known as complex regional pain syndrome type 2, is a rare chronic pain syndrome that is related to partial peripheral nerve injuries. This condition occurs when a nerve is cut off in the peripheral nervous system. These nerves extend from the central nervous system of the brain and spinal cord as well as branch out to serve the functionality of limbs and organs. If the case is severe enough, it is referred to as major causalgia, while minor causalgia describes less severe forms that are similar to reflex sympathetic dystrophy (RSD). The nerves that are affected by causalgia experience a chronic burning sensation as well as hypersensitivity in the area that is supplied by the nerve.

This condition is most common for people between the ages of 40-60, but it is also present in younger people as well.


Brachial plexus injuries are the reason behind causalgia, which involves all nerves that run from the neck to the arm. When nerve signals are disrupted, pain begins to increase as there as an increased release of the neurotransmitter norepinephrine which causes vascular symptoms. Risk factors for developing causalgia include trauma or amputation.


Those who suffer from causalgia experience symptoms including burning pain in the hand or foot within 24 hours of the initial injury. It is likely that any sensory stimulus will increase the pain. Changes in the vascular system are another symptom of causalgia. Blood flow will either increase or decrease due to the dilation or constriction of blood vessels. Scaly skin, still joints, tapering fingers, ridged nails, long, coarse hair or hair loss and changes in sweating are also common symptoms.

Stage 1: Severe burning pain at injury site with muscle spasms, restricted mobility, joint stiffness and rapid hair and nail growth.

Stage 2: Intense pain, increased swelling, diminishing nail and hair growth, muscle atrophy and worsening osteoporosis, joints thicken.

Stage 3: Irreversible bone and skin changes, and the pain may involve the entire limb. Severe muscle atrophy and severely limited mobility in affected areas. On occasion, the limb may become displaced.

If the condition is recognized early enough, it can sometimes dissipate and leave minimal changes to your body. Ideally, it will be recognized within the first two stages.

Medical Marijuana and Causalgia

Medical marijuana has proven to be effective in treating the symptoms of causalgia. Vaporized cannabis, even in low doses, could help provide a significant pain decrease for sufferers, which helps them to move normally.
