My Lord, Ms. Gem... What did the doctor give you that you have found no relief in 6 days? Skittles? I haven't had a flair up in ages, but usually Indometacin knocks that shiit back in 48 hours or so. Even after I was warned not to take it anymore due to it being a NSAID, I was given Colchicine which took a bit longer (and gave a nasty case of the runs....which hurt like hell when you had to run to the bathroom.....) but not 6 days. Personally, I found warm compresses gave me more temporary relief than cold.
Can't help ya with footwear: I used to wear a "boot" that I had to wear when I had a stress fracture in my foot.
Feel for you. That shiit hurts.
