The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.
Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

Limited heart rate variability, autonomic nervous system imbalance implicated in the aetiology of CFS


The Conversation: "The stress-response neural systems of chronic fatigue syndrome (CFS) patients remain on high alert even when they sleep, signalling that it’s not safe to relax, researchers have found.

Researchers also discovered that reduced heart rate variability, or changes in heart beat timing, are the best predictors of cognitive disturbances, such as concentration difficulties commonly reported by CFS sufferers. This adds to the growing body of evidence linking autonomic nervous system imbalance to this disorder.

The findings could lead to new ways to improve cognitive difficulties in people with CFS, which remains a poorly understood condition."


ETS results in limited (reduced) heart rate variability and alters the ANS (sympathetic and parasympathetic balance). This article might provide some insight into the cases where ETS resulted in a variety of unwelcome and detrimental side-effects, including fatigue, altered cognitive function ('brain fog'), etc.
