I would describe the conditions described above that are typical of the camino. There are long stretches with no one and nothing around. 1. Talk to your doctor and follow his/her advice.
2. I would get a health insurance travel policy that covers Spain, just in case.
3. Albergues will let you stay for 3 days max. If you can recover in three days you can take a bus to catch up to your pilgrim friends.
4. consider going with a companion that will stay with you if you have a bout of vertigo.
5 consider taking a travoy (search on amazon) if you companion is strong they can wheel you to the next town. they better be strong.
6. Listen to your body. It will tell you if you can go on or not. If you don't listen, you will suffer more consequences and reap the whirlwind.
7. consider starting in Sarria. You still get a compostela (200km) there are few large gaps away from civilization and there is an emergency room in Sarria. There are also major highways near the camino in this section which allow for quicker access for the ambulance if necessary.
"Why Worry? In life there are only two things to worry about:
Whether you are well,
or whether you are sick.
Now if you are well,
You have nothing to worry about.
And if you are sick,
You only have two things to worry about:
Whether you get better,
or whether you die.
If you get better,
You have nothing to worry about.
And if you die,
You only have two things to worry about:
Whether you go to heaven,
or whether you go to hell Now if you go to heaven,
You have nothing to worry about.
And if you go to hell, You’ll be too busy shaking hands with Your friends,
that you won't have time to worry.
So Why Worry?
