"Ow...," April whined while rubbing her temples. Raph looked up from his magazine, watching the human beside him.
"You okay?"
"Headache. Like... like the one after I messed up all those Kraang in TCRI," she replied with a groan, pearly eyes squeezed shut. The warrior's brow furrowed in concern, folding the corner of his page and shutting the magazine. April sighed and rubbed her eyes briefly, then her forehead and back to her temples. He blinked slowly, then recalled how Donnie used to get rather nasty migraines when they were kids. Mikey always insisted it was because he was working that big brain too much, but Splinter had explained that it was simply neuralgia, and taught them how to help their brother deal with the pain.
"Here," he said while shifting closer, reaching up and brushing her hands away from her head, pressing his palms to her temples as Sensei had shown them. Her eyes flew open, shoulders and arms suddenly going lax, and she sighed in relief at the sensation.
"Oh my god, that's awesome!," she chortled softly, leaning slightly into his touch. He hummed in response, carefully working out the tension he could feel in her muscles. April's eyes drifted shut again, far more content and comfortable than before, which Raph took as a good thing. "Ah... thanks, Raph," the red head sighed, letting his strong hands slide away. "Think I'll come to you next time I get a headache."
Reiki is a Japanese technique for stress reduction and relaxation that also promotes healing. It is administered by "laying on hands" and is based on the idea that an unseen "life force energy" flows through us and is what causes us to be alive. If one's "life force energy" is low, then we are more likely to get sick or feel stress, and if it is high, we are more capable of being happy and healthy. Would not be surprised if Splinter knew this technique. My parents learnt it when I was tiny to help me deal with my aches and pains, being the unhealthy and whiny brat I was, but these days they do indeed use it to help treat my migraines. Don't worry April, I can seriously sympathise.
Hail to the princess, baby!
