How is the foot with something like cycling? Big advocate here due to knee and hip demolition and similar arthritis / perma swelling that comes and goes.
I need natural walking or the treadmill over any bike due to the way my injury panned out.
Basically, I had muscle and hamstring atrophy in my leg due to an improperly diagnosed broken foot in Maui. The doctor missed my tibia was literally in half. Had recommended an aircast after a few weeks for the small breaks he mentioned, but basic EMT skill said to stay off it, so I did.
3 months later when I got back to the mainland I found out at a proper hospital I didn't just have 3 small breaks on my foot & a break in the calcaneus, but more importantly my tibia was broken straight down diagonal, and apparently should have had surgery performed on it ASAP for things to fuse back properly. Based on the gap after 3 months, it was apparently over 30mm when broken.
Problem is that US healthcare isn't taken in Hawaii (at least Maui) - I was fully covered in any other state... maybe not Alaska.
So I had to go to the equivalent of a doctor you'd take your kid to for a fever, a GP per se. I maintained it myself for 3 months until I flew back to NJ as it still didn't feel weight bearing ready, while staying off the foot - which apparently stopped me from doing serious damage.
Thing hurts constantly, but walking actually helped build back the muscle in the leg & of course helped stretch my hamstring back to usable levels over time. No PT when you don't have surgery on the foot.
tl;dr - Get the vacation insurance plan you usually avoid if you're taking a trip to Hawaii, or other countries - if only for medical. A lot of plans are only $20-50, some include comprehensive coverage including full medical, dental, etc.
