Brain Tumor update

I finally started my radiation therapy--it's going well---but my head  ---(the one that let a huge brain tumor grow in it for probably several years) is rejecting my sutures---so it's trying to spit them out through the healed incision--it was almost perfectly healed--now it's constantly oozing and scabing up then re-opening.  When they place my radiation mask on it's so tight that it always opens up my scab---it's really not pleasant --I always have a leaky head now!
