Replying to Heel pain help

hey, hi, hello! for the past few seasons i've been having heel pain lasting up to weeks after landing hard on my left foot. when i went to the doctor a few years ago they said it was because my growth plate was growing at a different time than the rest of my foot, but i'm 17 now and my foot has stopped growing but the pain is still killing me and stopping me from going bigger. anyone experiencing something similar or could hook me up with some advice excluding gel soles? thanks, friends.
