My husband has sciatica after a back injury this winter. It's usually manageable, but it does become painful when he twists, sleeps wrong, or sits for too long. We have a road trip coming up and of course I don't want him to get injured! Our trip has 3 stops (2 days at each stop) and each one is 3 hours from the other. What can we do to make the trip comfortable? How many breaks should we take during each leg of the trip? We have a couple of months to get him prepared and buy any necessary braces, tools, or seat boosters. Thoughts? We're only in our mid-30s, so we're not ready to give up travelling forever!
