I assume you are not talking about social security disability (as that is only for permanent disability) so I assume that this is something more like Worker's Comp? In any event, you needed to sign up with someone for whatever type of disability you will be receiving and I am sure that they gave you paperwork about the payments, eligibility, return to work etc. That is going to be your best source of information short of picking up the phone and calling them.
Keep in mind that there is a reason for allowing you to collect disability for that 6 week period after major surgery. In most cases major surgery will leave you exhausted, weak and needing assistance so that you don't mess up whatever it is that they have just fixed. If your recovery is quick, you may well be up to doing some shopping, but it is certainly not in your best interests to grab a whole lot of jobs you then need to cancel because you are not feeling strong enough to do them.
So do take advantage of some down time to catch up on your reading or mending or other non-strenuous activity.
