Half a month after pneumothorax surgery, there is a burning sensation with sweating at night, which may be related to autonomic nervous system dysfunction, low immunity or combined infection. 1. Autonomic dysfunction in the body: pneumothorax operation may stimulate the intercostal nerve or pleural nerve endings, and the autonomic dysfunction may be manifested as chest tightness, shortness of breath, panic, loss of appetite, nausea, abdominal distension, diarrhea, headache, generalized skin warmth, body temperature is normal, but the body temperature feels hot and cold, and sweating. 2. Low immunity: If the patient has low immunity after pneumothorax surgery due to surgical trauma or other reasons, the parasympathetic nerves will be excited at night, which can be manifested as burning sensation and sweating all over the body. 3. Combined infection: If combined with systemic or local infection, the release of inflammatory mediators will lead to body pain and fever, manifested as burning sensation accompanied by sweating. Half a month after pneumothorax surgery, burning sensation with sweating at night, we suggest that patients go to the hospital as soon as possible, so as not to delay the condition.
