Wonderful to hear that you are seeing improvement! And yes, the BFST Achilles Wrap would help to speed up your recovery after surgery.
As to using the 2 products in combination, use the ColdCure Wrap after being on your feet to reduce swelling and inflammation, then wait about 45 minutes before using the BFST. Also, if you know you are going to be active, use the BFST before the activity, followed by ColdCure.
For best results try to fit in 3 to 4 twenty minute BFST treatments per day!
As to using your Cold Cure Wrap on the plane; the gels are food grade medical products and are not liquids. Make sure you bring your instructions and even you invoice if you have it, just in case you have issues at security. I am not sure how you would cool the gels on the plane!
