Hi, am arriving in St. Jean 5 weeks from today with friends/family to start the Camino. Training has gone well but I am having to manage an ankle problem that occasionally flares up (have gone through appropriate medical consultations and just need to manage it). Whilst I know I can ask for ice in bars or buy packs of frozen peas in supermarkets to use as ice packs, has anyone come across instant ice packs in pharmacies along the Camino route? I mean the type you squeeze setting off a chemical reaction in the pack that results in them freezing for ~40 minutes.
