Man I don't blame you for not wanting your head opened back up. I am a young 66 year old just starting the wait and watch game. I had emergency surgery Sept 27th, 2018. Did 6 weeks of radiation and 6 weeks of tremozolomide. Right now everything looks good even looks like it's backing off a little. I'm doing old Chinese medicine and therapeutic doses of vitamin C IV drip every other week. I will pray yours backs off for good.
