swelling after brain tumour removed
 

Hi, new to this forum. I had a meningioma brain tumour removed 5 weeks ago, very large, over my right ear. I was steadily improving, with the some swelling around my right eye. last week, the swelling increased, rather than decreased. I went back to the hospital, mentioned that I felt pressure in the back of my neck. I do not have an infection. They sent me home and said, come back it it gets worse, and if my neck become so stiff, I can't move it. So I am back home again.
this morning my eye was so puffy it was almost shut.
1) has anyone experienced this swelling so long after surgery, or that it gets worse not better.
2) any advise is helpful. It is so hard to know what is happening and what is OK or what is dangerous.
thanks.
