After lipoma surgery there is pain on eyes and head. Why this happen ?

Hello. Thank you for posting.

This may be postoperative pain. I assume it's in the same area as the surgery? However, if you are concerned, contact the doctor who did the procedure and let him or her know what you are experiencing to be sure it's normal.
