Speaking to the Official Club Website, Town manager Joe Royle revealed: "This is a big, big week for Chris. We are looking at him making a significant step forward over the next four or five days.
"If that doesn't happen, the chances are he will have to seek a second or third opinion from specialists. That could mean further surgery and given the fact that we are now in February, any operation could mean he would be out for the season."
Makin has not appeared for the club since the end of August.
