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.

Recurrent hyperhidrosis is another potential side effect from hyperhidrosis surgery

The Society of Thoracic Surgeons Expert Consensus for the Surgical Treatment of Hyperhidrosis -- Cerfolio et al. 91 (5): 1642 -- The Annals of Thoracic Surgery: "Recurrent hyperhidrosis is another potential side effect from hyperhidrosis surgery. Incidence rates vary considerably and have been described as 0% to 65%"

The Society of Thoracic Surgeons Expert Consensus for the Surgical Treatment of Hyperhidrosis -- Cerfolio et al. 91 (5): 1642 -- The Annals of Thoracic Surgery: "Because the goal of this procedure is to improve quality of life, complications should be minimal and essentially eliminated. The primary side effects of hyperhidrosis surgery include CH, bradycardia, and Horner's syndrome. It is important for patients to be aware, however, of all of the possible complications that can occur. In general, "the higher the level of blockade on the chain, the higher is the expected regret rate" [26]."

Thoracoscopic Sympathectomy for Isolated Facial Blushing -- Licht et al. 81 (5): 1863 -- The Annals of Thoracic Surgery

Thoracoscopic Sympathectomy for Isolated Facial Blushing -- Licht et al. 81 (5): 1863 -- The Annals of Thoracic Surgery: "Criticism has been raised about surgical treatment for facial blushing because there is very little evidence that the patients most likely to pursue surgical treatment for facial blushing actually blush more readily and intensely than other people [21]. It has been pointed out that facial blood flow during acute embarrassment seems to be unrelated to ratings of the self-reported frequency of blushing [22]. On the other hand, self-consciousness and fear of blushing correlate well with subjective estimates of blushing frequency and intensity [22]. It has therefore been suggested that if the source of the patient's problem is anxiety about blushing rather than blushing per se, anxiety would be a more appropriate target for treatment than permanently eliminating the normal regulation of facial blood flow and sweating [21]."

The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer

The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer: "Immediately after sympathectomy, the contralateral right arm became increasingly cold and cyanotic and the patient complained of chronic painful coldness and severe cold-intolerance in the right arm. Attempts to pharmacologically vasodilate the arm with felodipine did not affect the local vasoconstriction and pain. Dorsal column stimulation (associated with symmetrical paraesthesia in both arms) induced an immediate and marked (ten-fold) increase in skin blood flow in the right arm (and in the leg), whereas skin blood flow in the left arm remained unaffected. The lack of vasomotor response in the left arm was not due to maximal vasodilatation at rest, since skin blood flow in the left arm showed a normal capacity for axon reflex vasodilatation following antidromic activation of sensory afferents. The results suggest that the marked vasodilatation induced by dorsal column stimulation is mediated by sympathetic vasomotor fibres, via modulation of central neuronal circuits involved in the regulation of skin sympathetic discharge."
