Wayfarer said "we were stiff and sore from the walk the day before" never heard of such a thing! On the Camino? Pop into a pharmacy (which, by the way, is where you will find someone who can speak English if that is a problem, not the clerks but the Head Pharmacist is the one to look for!) pop into a pharmacy and ask for Radian B, a cream made in France works like BenGay but no smell!!! warms up on touch and helps to soothe aches and pains without destroying friendships. There is also a homeopathic cream Traumel S (like trauma a name easy to remember) but like so many homeopathics it takes a long long time before it kicks in and becomes effective. Walking is the best way to relieve aches and pains just mind your cadence and your stance, slouching or favoring a leg, ankle, knee, etc is a sure fire shortcut for blisters.
