Narrative:

We were descending on the bdega 3 RNAV arrival in the vicinity of bdega. We were given a descend via clearance except to maintain 11;000 ft. As we were descending below 13;000 ft. We simultaneously encountered wake turbulence from an A380 as ATC amended our altitude to 12;000 ft. And cautioned us for wake turbulence. We reported that we experienced the wake turbulence and were then given a further descent which we denied and remained level at 12;800 ft. To allow for more separation. We were then issued a pilots discretion descent. I called back to check on crew and passengers. No injuries reported; however [a] flight attendant mentioned to the first officer as she was leaving the aircraft that she may have re-injured her tail bone.this is a constant problem going into sfo. There are certain airports we operate into (sfo; lax) where wake turbulence is a constant problem and an ongoing threat. Our air traffic controllers do an excellent job with the resources given and the volume of traffic they have to manage; however I would like to see some additional arrival spacing from heavies when flying into these airports. As a side note; I think the FAA needs to re-evaluate the categorization of the 757 and solicit feedback from pilots that deal with it on a daily basis.
