Hehe, just like me. I used to have a headache after I finished it, but I was afraid to tell my parents because they worked hard and spent a lot of money to treat me. I was afraid they would be worried when they knew. But after about half a year, I slowly forgot my headache, and then I found that my headache stopped. Up to now (the fourth year after operation), there has been no recurrence, but sometimes it hurts to concentrate. Then my head hurts a little when I have a cold and a fever, but these are nothing. I think it should be just after surgery, the inflammation has not been completely eliminated, and the wound has not healed.
