need help getting card - california ID but no address...

Last June I had surgery on my hip and i'm still in constant pain so I figured its about time to get a medical card. My problem is that since then i have lost my house in california. I currently attend university of Arizona and i go back to cali on all of my breaks but i live with other people. My drivers license is california but the address on the license is not mine anymore. Can I use my arizona address with my california ID?? Do I have a chance at being able to get a medical card?
Thanks for the help
Dan.
