Will I get better during radiation therapy?

Anyways I brain surgery for a brain tumor on Oct 21st and have had some side affects after the surgery; I am relearning how to walk and my right side coordination is now terrible. I also am relearning how to swallow, and my eyes are very sensitive to light.I start radiation In the first week of Dec. The surgeon didn't cut any nerves but I still have a small part of the tumor left in my head. My question is will radiation clear up some of my symptoms and how long? My doctors hope it will but I would like somebody's opinion who actually went through something like this.
