DB::raw in Laravel takes long time

I've a Laravel 5.2 application, I need to make an advanced query to the database so I'm trying to use the DB::raw expression, mainly, my query is like this:

SELECT * FROM TableA AS s
        LEFT JOIN TableB AS l FORCE INDEX FOR JOIN (idx_1) 
        ON ((s.mid = l.mid) AND (l.id = 1))
        LEFT JOIN TableC AS f FORCE INDEX FOR JOIN (idx_C_1)"
        ON (s.mid = f.mid)
        LEFT JOIN TableD as bl FORCE INDEX FOR JOIN (idx_D_1)
        ON ((bl.ACid = s.ACid) AND ((bl.userid = 1) OR (bl.userid = -1)) AND (bl.type = 1))
        LEFT JOIN TableE AS wl FORCE INDEX FOR JOIN (idx_E_1)
        ON ((wl.sid = s.sid) AND ((wl.userid = 1) AND (wl.type = 2)))
        LEFT JOIN TableF AS gwl FORCE INDEX FOR JOIN (idx_F_1)
        ON ((gwl.sid = s.sid) AND ((gwl.userid = -1) AND (gwl.type = 2)))
        WHERE (bl.sid IS NULL)

So, it just get stucked in Laravel and doesnt show me a response, so I executed it in PHPmyAdmin and the response is very very fast. In Laravel I have this:

   $query=DB::select(DB::raw(TheQueryAbove))
            ->orderBy('s.reversestamp', 'asc')
            ->offset(0)
            ->limit(26)
            ->paginate(10);

So, why it takes so long? or how can I test it to find the cause? I already tried: dd(DB::select(DB::raw(TheQueryAbove)))->toSql(); with no success, it doesnt even get printed. Thanks!
