Tommaso's knee replacement surgery can't wait - please help us cover the bill

Tommaso was diagnosed with an aortic valve defect in August. The surgeon at Milan Orthopedic Institute recommended knee replacement surgery, and He is scheduled for October. The hospital's financial office gave us a written estimate of $1,200, and after what the government subsidy will pay we're still $900 short. my son has been in and out of Milan Orthopedic Institute since August. The doctors say an aortic valve defect will get worse without knee replacement surgery. We have emptied our savings and borrowed from relatives, but the estimate of $1,200 is more than we can find. While we wait, Tommaso struggles with daily life and can't look after the children alone. His family has taken turns caring for him, and I've cut my own work hours to be there. Rehabilitation is expected to take about 7 weeks. During that time Tommaso won't be able to look after the children alone, so the costs keep growing. I'll pay the hospital and pharmacy directly and post every receipt in the updates section. Where the $900 goes: • Physiotherapy sessions: $300 • Post-operative medication: $130 • Pre-operative tests and imaging: $470 Please ask me anything in the questions section. I'll answer honestly and quickly.
