Increased swelling 3 weeks post op?

I am exactly 3 weeks post op today from clipping of 10mm in middle right artery. The entire right side of my face and head is MORE swollen the past few days than it was last week. I am sitting up in a chair almost all day, only laying down at night. I also feel worse this week than last week. Is this regression normal? Going back to neuro on Monday but can't help but me worried.

Can only suggest...call your neurosurgeon....do not wait...
