After pituitary cyst surgery, patients may experience discomfort such as headaches. Because pituitary cyst surgery itself is an invasive procedure, headaches are a normal phenomenon. During surgery, the removal of the pituitary tumor may damage the surrounding bone and nerve vessels, etc. In addition, during the removal of the tumor and the postoperative recovery process, there will be the release of inflammatory substances, which may cause headaches, and may also be caused by the sequelae of the surgery, such as cerebral edema, etc. If the symptoms persist for too long, the headache may be caused by the tumor. If the headache lasts for a long time and there are other symptoms such as visual disturbances, nausea and vomiting, it is recommended to go to the hospital in time for a detailed examination to check whether there are other abnormalities in the brain, and then according to the doctor’s recommendation, carry out special treatment.
