you've got to give the physio a chance - it's all a matter of slowly building up to what you CAN do.
perfect case in point: a friend of mine had surgery just over 6 weeks ago on his arm, to reattach muscles to the bone.
on sunday he took the kids to the pool, couldn't help himself just HAD to get involved in a bombing comp with the young ones.
he fractured the arm that's been operated on.
the next day he was supposed to be getting the all clear on returning to his normal stuff.
instead he's now in a plaster cast and not able to do things for a good 3 months.
so yes, you will need to slow down. but use the slow down time to heal & find different things that you CAN do.
