sorry about the headache, that sucks. but i do object to calling our cellular carbon based lifeform a "meat sack".
yes, bodies are prone to suffering, but also reveal glory beyond ourselves. cells working together, evolving communities of consciousness creating us moment by moment.
i get it that bodies feel like prisons sometimes. but i don't see how disparaging them is helpful.
treat your lived body kindly. perhaps the headache is from neck or shoulder tension. try massage.
