Ice helps mine. I also found a great physical therapist who does deep tissue massage and it has really lowered the pain in my left achilles which used to be really sore.
Don't ignore the pain or just push through it for too long. I had achilles debridement surgery this past summer which totally healed my right one (I had ignored the pain and pushed myself for about 3 seasons), but I don't recommend that as a first option.
