Hi! :) I'm not sure if you're explaining the situation to us, or asking for a proofreading. I'll take it as a proofreading, if that's OK?
"Last year my mother received a head injury. Even now, she is very sensitive. She always get headaches, as if someone is pulling at her hair. On one part of the skull, it feels like fluid has built up. The doctor told her that the treatment is finished, but she is still suffering. We will email you her x-rays. Please advise us, what about reiki treatment? She is very fragile. Is reiki suitable for her?"
