acetephetamine and liver damage

I was being a very foolish teenager and was using hydrocodone/acetaphetamine 5/500 to get high i would take 4 some days and sometimes up to 6 for a few days but then i stopped becuase i found out it was dangerous for my liver have i sustained permanent damage or should i go to the e.r im not sure what to do i think i freaked myself out but i would just like to be sure if im ok or if i should go to the hospital
