I ran into the same thing yesterday. I had my CK over 7 mos ago and yesterday, between the same feeling, (ie: fullness, wonky head, etc), I caved and put in a call to BI and spoke to the radio-oncol dr on call.... took some ibuprofen as first step to anti-inflammatory... suppose to call my radio-oncologist today for follow up to last night.
I do know that it is not usual for post treatment swelling to occur down the road from radio-surgery (all forms). It's not typical, but not unusual either. I do have some Decacrap here if need be but trying to avoid it if I can. Please let me know what they say as I'd also be curious... will see what BI says as well. I'm not due for my next MRI until Feb but they may pull me in sooner to see if there is edema going on.
Hang in there and pls let me know what they say. I think we are in the same boat BUT there are paddles for us to use!
