Strangely whenever we receive the stockings, they're basically a loose stocking in a shipping envelope - if sent by mail by the hospital - or handed to him opened. I suppose we can go by the date his CC was charged and add a week or so for the expiry date.
Well, I received a PM that said that modifying the stocking could cause problems - ie blood clots if not well done, so I won't modify and will look into the roll on some more. The concern I have is how safe it is for a relatively new skin graft. I haven't been able to find ingredients in an admittedly short look - I found a funnel page for the product itself - didn't like that and then possibly a manufacturer link that showed me dealers in my area - mostly the medical aid shops.
Thank you to everyone for your suggestions. I do appreciate it!
