This is awesome! What a great resource to have at home and use daily. The pool definitely helps circulation issues. I was fortunate to have access to pools on a regular basis post-op and it made such a difference for me.
I can relate with the inability to keep a foot down for very long. It took what felt like forever for that to improve and it happened very gradually. Post-op swelling with dependency is normal even without CRPS and can take months to resolve. Especially with ankle surgery...
I'm so glad to hear the grinding pain is gone and his range is better. That is going to stave off a host of other problems down the road.
Keep up the good work! Your son is fortunate to have such great support. He will keep getting better in time.
