We will do everything to make this procedure as safe as possible. However, complications can occur. These fall into 3 groups. 1. Anaesthetic related, 2. General complications, 3. Specific to ETS.
Compensatory sweating (CS). This is where you now sweat more in another area of your body. This is common, but generally mild. However, in one in 50 cases, CS can be troublesome, equal to or worse than the original problem. Unfortunately, it is very difficult to predict.
Horner’s syndrome occurs when the sympathetic nerve supply to the eye is damaged. This will occur if the Stellate ganglion is inadvertently ablated. This results in a droopy eyelid and constricted pupil. This occurs rarely, one in 1000 cases.
Gustatory sweating is where you sweat on your face following eating, particularly in response to spicy foods. This occurs in about 3% and is generally mild.
Chest complications such as pneumothorax or chest infections are unusual, but can occur. It is common to experience heaviness in the chest and sharp pain often at the back, particularly with coughing and sneezing in the first week.
A small number of patients (less than 5%) notice a marked difference in temperature between the upper torso and lower torso. In rare cases, it can become somewhat disconcerting.
