probably this should work

// Filter wp_nav_menu() to add profile link
add_filter( 'wp_nav_menu_items', 'my_nav_menu_profile_link' );

function my_nav_menu_profile_link($menu , $args) {
    if (is_user_logged_in() && $args->theme_location == 'primary') {
        $current_user = wp_get_current_user();
        $user=$current_user->user_nicename ;
        $profilelink = '<li><a href="/forums/users/' . $user . '/edit">Edit Profile</a></li>';
        $menu = $menu . $profilelink;
    }
	return $menu;
  
}
