Here's a possible introduction for a fundraising appeal:

"Hello, I'm sanjaya, and I'm reaching out for help during a challenging time. I've been diagnosed with a spinal condition that requires urgent surgery, but unfortunately, the medical expenses are beyond my current financial means. I'm turning to the kindness of friends, family, and the community for support. Any contribution, big or small, would bring me closer to getting the treatment I need and resuming a healthy life. Thank you for considering my request."
