Thanks for providing more information.
Endoscopic thoracic Sympathectomy is a surgical procedure to cut the nerves (in sympathetic blocks nerves are only blocked while in sympathectomy they are cut, so it is a permanent sort of procedure).
ETS has normal risks of surgery, such as bleeding and infection, and several specific risks, including permanent and unavoidable changes in nerve function like loss of feelings on the face,the shoulders, a decrease in the ability to sweat.
It can even affect areas of the back, groin and thighs, and even damage to the lungs or heart(Pneumothroax has been seen in 2 % of patients).
It can also result in inability to raise heart rate during physical activity resulting in cardiac problem.
A severe possible consequence of thoracic sympathectomy is corposcindosis (split-body syndrome), in which the patient feels that he or she is living in two separate bodies.
So in my opinion,you should firstly discuss it with your doctor as it has high risk and it's good to continue propanolol.
You can ask your doctor for other option like Clonidine.
Even you can consult a dermatologist for a clinical examination and if required your doctor may prescribe some medications like antibiotics,topical azelaic acid such as Finacea/Skinoren may help reduce inflammatory lesions and redness.
You can ask your doctor and refer to surgeon.
