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.

The response to injury in the perihperal nervous system

Persisting neurones switch to a ‘survivor’ phenotype and the expression of hundreds of genes8,9 is changed to compensate for the loss or diminution of target-derived neurotrophic factors,10 and in order to regrow their axons across the site of the injury and back into the periphery. Proximal changes, such as synaptic reorganisation in the cortex1113 and spinal cord, occur upstream of axotomised first-order motor and sensory neurones, and may influence the functional outcome months or even years later.1416 Distal to the injury, a series of molecular and cellular events, some simultaneous, others consecutive, and collectively called Wallerian degeneration, is triggered throughout the distal nerve stump and within a small reactive zone at the tip of the proximal stump (Fig. 2Go).1719

'Improved sympathectomy' - is it an oxymoron?

"also it seems like the more bad and negative affects were from 10 to 12 years ago when they had just started performing the surgery.. they must have inproved it alot by now.?"
I'd like to echo what some others have said just so you are completely clear on this issue. This procedure has been performed since the 1920's. Yes, the 1920's. In the 1980's they started to do it using "keyhole" surgery which means they don't have to make a big incision. But, the surgery is no different than what they've been doing for the last 70+ years. It's a nerve injury. You can't "improve" they way you inflict a nerve injury. You can't injure the nerve in some "special" way such that the injury suddenly has a different effect on the body.

The functional name for the this surgery is "sympathetic denervation". It's not some super-advanced, modern cure based on recent discoveries in neurophysiology. It's a primitive, destructive procedure. It's a method used on animals for research. It's brute force method...destroy the pathways to the sweat glands over a large region. Unfortunately, it destroys pathways to and from many other organs including the heart and lungs and causes a large number of neuropathological dysfunction. That hasn't changed in the last ten years. It will not and cannot change in the next 1000 years because it will still be a nerve injury 1000 years from now. I'm not making this up. It's a simple fact. Don't let some doctor take advantage of your ignorance
