I guess it depends on how you are feeling, did you have unders or overs? If unders then in theory shouldn’t be doing any heavy lifting for six weeks light stuff after two weeks, but frankly the I ly person that will know is you. I guess you need to work out what sort of effort you need to put in to a lift and try to judge if you are Upto it, but if you are doing really physical stuff it could be a while for them to heal if unders.
