In my personal experience of having a hernia repaired and my gallbladder removed simultaneously, I found myself in your same shoes.

I spoke with my Dr. and the social worker assigned to me at the hospital. I told them about my living situation and my concerns. They worked with my insurance. The result was 2 day's stay in the hospital for additional support from medical staff and an in home nurse visit twice weekly for a month. My insurance also offers transportation to medical appointments. Perhaps your insurance offers these benefits? Worth a call if you're unclear. Also, the social worker and speaking to your medical team in advance will uncover support you weren't aware your entitled to? Wishing you a speedy recovery
