I had a menengianoma removed from my right temporal lobe three weeks ago . everthing went as expected until I got my stitches removed . I am now off my steroids as of three days ago and now am getting swelling on my face . is this something to worry about ?
You may be having a rebound phenomenon of swelling due to cortisol suppression by the high dose steroids you were probably on for the brain surgery which were stopped.  You should notify your physician of this change, but things should get better over the next week or so.
