How long after surgery can I start ibuprofen. Can I rotate it into my pain medication? I am 39, 3 days post-op.

I would avoid ibuprofen and other non steroidal antiinflammatory medication until cleared by your doctor, as it can increase risks for bleeding. This time frame can vary 1-2 weeks. 

Most surgeons are ok with you taking ibuprofen after these operations depending on which medicines you are already on.  I would check with your surgeon before adding additional meds.
