If you don't make progress in the coming weeks, be sure they do adequate work up to rule out any surgical mishaps. I wonder about the numbness you describe. Could that be CRPS, nerves pressed on by post op swelling or a nerve that got nicked or smooshed by scar tissue etc.? it is important to find and address any pain contributors so you can heal whether this is CRPS or ticked off foot. Morphine at 8 weeks out sounds heavy to me for any remotely typical healing spectrum. Obviously your foot hurts like hell for whatever reason.
