In the Bay area, even if you have a temporary disability, a medical cert will get you all kinds of options for transit. But without certification, it's all private pay. There are numerous Medical Transport Non-emergency companies that charge anywhere from $30-200 to get someone to a dr. appointment (rate depending on how ambulatory you are). Or it's taxis/uber if you can't walk at all. Can you talk to your doctor about getting a temporary medical certification? Does that give you more options where you live? The other thing we have here is an local online community and it's pretty easy to find a (somewhat close) neighbor to pay for rides you arrange in advance; often just gas and a free lunch will do it.
