I can't imagine they would really expect you to be away from your family for 30 days..
And if you did would WC pay all costs?? travel, meals , lodging??
If you have the name of the place, you can ask our RSD forum members about it too.
No use going there if it might be a waste of time..
Do you have an atty on your side to help with this? Often with ongoing care needed like RSD requires, a good atty is needed to make sure you get bes results from WC.
You might also post on our RSD/CRPS forum, members may know of closer drs or clinics, that can be considered.
Was your dx in 2012, or recently?
Usually some injection/blocks are the best to try early on to stop, slow or reverse it.
But the RSD/CRPS forum is best for that information.

* It might be wise to not post any specific, identifiable details as WC may do searches if you claim may become very costly.*
