May I request some help - in the form of information - from the members of this always kind forum?

I have a friend who lives in Sacramento, California. She has no income at the moment, because she's minding her dying mother. She fractured her leg some months ago, and - apparently because of the way the US medical system works - she has no automatic right to free or cheap treatment.

She went to the hospital, and was there told of a women's clinic in a nearby city, but the people in the clinic asked for proof of income, and when she said she had none, asked for proof of her mother's income - a pension. She brought this, and was told that she'd have to pay some hundreds of dollars for treatment, based on this income. But unfortunately her mother's drugs actually eat up all of this money, apart from whatever is needed for food and household expenses. (Thise people don't exactly live high.)

Is there such a thing as a real free clinic, or cheap clinic, in the Sacramento area where she can get her leg mended? Otherwise she's not going to get it done, apparently.
