I didn't have any problem after radiation about drainage. only after surgery which was Sept 2 I had problems with my right ear draining. Last thursday it finally cleared up to where I could hear. My ENT said it was part from radiation and the swelling from surgery and will get better.

Hope this helps
Love
Terry
