Usually, you can walk in house first week, then depends on your pain after. I wish you asked your surgeon this question, because it depends on how extensive the surgery is and how big the cut and if you are prone to bleeding with early walk.

Immediately, you are at a high risk for blood clots.

Hello

If I can make a suggestion, it is not common place to seek another non-surgeon’s advice when you have been given your discharge instructions with follow-up parameters.
If you were not given post op care instruction, you should contact your surgeon for guidance

Thank you.
