how can i get all post for me and for user who i follow him

how can i get all post for me and for user who i follow him

i have 3 table.
1st is for user info. 2nd is for post where user insert to it and relation
with user table by user_id. 3rd is for user who i follow him and relation
with user table by user_id.
now in home page i need to show all posts where i insert on it and where
user i follow him insert into table post.
i will try to make this MySQL by :-
SELECT * FROM users ,
(SELECT * FROM events where ev_user_id in
(
( select * from follow where follow.fo_user_id = '".$user_id."' )
, '".$user_id."'
)
) as post
where post.ev_user_id = users.id
order by post.ev_date DESC limit $to , $from
where $user_id is id for user.
here i get error that:-
Operand should contain 1 column(s)
if i follow one user its work, but when i follow more than one user, its
display above error.
how can i get all post for me and for user who i follow him
