Hậu's hip replacement surgery can't wait - please help us cover the bill

Hậu was diagnosed with a deviated septum causing chronic infections in March. The surgeon at Hồ Chí Minh City University Hospital recommended hip replacement surgery, and He is scheduled for June. The hospital's financial office gave us a written estimate of $830, and after what the public health scheme will pay we're still $500 short. my son has been in and out of Hồ Chí Minh City University Hospital since March. The doctors say a deviated septum causing chronic infections will get worse without hip replacement surgery. We have emptied our savings and borrowed from relatives, but the estimate of $830 is more than we can find. While we wait, Hậu struggles with daily life and can't drive. His family has taken turns caring for him, and I've cut my own work hours to be there. The recovery period is expected to take about 4 weeks. During that time Hậu won't be able to drive, so the costs keep growing. I'll pay the hospital and pharmacy directly and post every receipt in the updates section. Where the $500 goes: • Pre-operative tests and imaging: $110 • Hospital stay (3 nights): $350 • Travel and lodging for the family: $40 I never thought I'd be the one asking, and I'm grateful for every bit of support.
