How can I procure steroid cream?

I live in the Los Angeles area (California, USA). And I%26#039;m looking to get my hands on some steroid cream for my knees. I took some cycling classes and applied too much pressure on both of my knees. It%26#039;s been a year and I still feel some pain. |||First get some Poison Ivy. Then, go to the E.R. and tell them steroid shots have never helped in the past. Then they%26#039;ll prescribe steroid cream for you to try.
