Are you serious? It started yesterday, is minor, and has a clear cause, and you’re looking at flights to return home and stop traveling?!? Maybe you’re not cut out to be a nomad if you’re ready to give up that quickly. Life happens while you’re a nomad. You’ll get injured, sick and heartbroken, you may lose your job. These things happen. They’re the same when you’re on the road as when you’re in one place. You need to ask yourself what you need to heal, and then do that. You walked a lot yesterday. To heal, you need some rest for a day or two. You don’t need to take a flight anywhere, which will just put more strain on your foot. Just chill in your Airbnb for a day, elevate your foot, watch Netflix, take a painkiller. You’ll feel better soon! Going home isn’t going to help.
