Camino: Day 4; another problem

This morning I said goodbye to my Italian knight (well he was the one who came along when I was robbed and then escorted me everywhere). It was sad to say goodbye but he wanted to do 2 stages today (so 33kms) and I only wanted to do one (13kms). So, it was better to say goodbye.

One of the Spaniards went with him and the other 3 Spaniards made an early departure for the 13kms, while I stayed back to walk with the Spaniard who had joined the group alone. He was making a late start to go to the post office and send some excess luggage home.

I chose to walk with Pedro because I was having to walk too fast with all the others and I felt that with just him we could walk a bit slower. Put 6 men in a group and they all seemed to be trying to walk the fastest.

Anyway, regardless of my slow down today I now have the results of walking too fast. My left knee became very painful in the last hour of hiking today.

I've been googling a solution. It seems that walking too fast and pushing beyond what you are used to can cause such problems. Rest seems the best advice at this stage. Ice was also mentioned, but I'm already cold here.

I had felt I needed to walk with the group for safety. But by doing so it seems that I'm doing damage to my knee. Can I win?

Tomorrow I'll see if I can take a bus to the next stop. And rest. And see where that leads me.

Oh, and today we walked through a field of pigs! ... But they were all sleeping :(. An English guy turned up here today, he said the pigs licked him, and showed me a video. I'm a bit jealous really.

This town, called Real de la Jarra, has 2 castles. They are possibly really cool, but I'm barely walking so I really don't know.
