“How long does it take to recover from shoulder bone spur surgery?”

Normally, 4-12 weeks.

The answer is best served by the very MD that will be your shoulder surgeon. He can tell by the tissue upon which he works its healing capacity. I would suggest eating the bone-in sardines to help the bone itself to heal fastest. Product from Ecological Formulas named Placenta that helps the soft tissue to heal better as well. Listen to his postop instructions and follow to the "T".
