We found out the headaches are from brain swelling. I read about this online and learned that the radiation causes an accumulation of dead cells to gather and this will press on the brain. Our brain doesn't have a lymph node system like our body does so it takes time for the dead cells to disperse.
So he was given a steroid for the headaches. He was on a steroid before and hated them but this is a low dose that he won't be on long.
He also will take something for the stomach upset.
Yesterday was bad for Steven. He sat (the short time he was up) with his head in his hands and rocked to ease the stomach cramps. I'm praying these new meds start working soon.
