How do you deal with pain from a cuncussion?

im 18 ive had a bunch of head injuries from skating running dancing just everything i guess ive shaken it up too much since my last cuncussion & maybe i didnt give it enough time 2 heal from everything but now im hella scared cuz my head is all messed up all the time an it even makes it hurt when i get drunk which used to take away all the pain from my last cuncussion and i cant take pills for the pain cuz my heart so wat do i do about the pain idk wat to do :(
