9th week after ankle surgery, and still need 2 crutches to walk with limp. Is this normal? Swelling & pain in ankle. When can I walk without crutches?

Shake, rattle, roll. There is ankle surgery and there is ankle surgery. Depending on the extent of the damage and repair, the time until resolution varies greatly. Swelling and pain can be a sign of some degree of instability. Ask the surgeon as to his take on your healing.
Good question . Ask your physician. The answer depends on what the amount of damage was, what the diagnosis was, what the uextent was etc.
Varies. It really depends on the nature of the condition and the surgery you had. Don't hesitate to discuss directly with your physician.
