Hey Karen,
Since you had your CK in Nov, 2010 (3 mos "toastie postie"), you are in that timeframe that if things decide to crop up, they may. Please don't disregard what is going on.... as your homework has shown, some post-radio can occur and you should be notifying your CK team (ie: radio-onc AND neuro-onc, possibly via the onc-nurse) that these things are going on. They can prescribe short-term course of anti-inflammatories/steroids as tumor swelling can occur (sometimes part of the process) and if they do prescribe, can help alliviate what is going on. Glad to hear you are starting VT and here's hoping it helps the cause!
Reminder to all radio-patients.... through homework, by advise of many radio docs (not just our own by also via the docs that volunteer their time on the CK forums, etc) that follow ups should be done with the treating teams, esp immediate post-radio. There are possibilities (not always, but sometimes) that things may crop up between immediate post-treatment to approx 2 yrs down the road and the treating teams should always be alerted if something is going on that just doesn't seem right as there are things they can do to try to help the cause.
As we all know, "individual results may vary" and these things don't happen to everyone, but if they do, please alert your radio team so they can best assist.
Hang in there, all.... .wellness wishes to you and hoping each day becomes better.
Phyl
