It depends on your financial situation but I think it's better to go back when you feel like your better and not in pain.Im thinking of going back soon but only because I feel better even though my jobs probably gone as I haven't worked for 14 months as I felt I nearly died and I wanted to take my time to recover,my boss said take as long as you need but he probably didn't mean this long.I had my takedown on 13th Nov.
