I have read so many devastating stories from people who developed tendonitis and either lost a few days walking or had to quit altogether. In researching ways to avoid this nasty problem, I see where it is stressed to do a proper warm up before beginning. The other thing was to avoid prolonged activity that causes it. I can do the warm up for sure. But I have to walk for a prolonged time. Are there other things that can be done to avoid tendonitis before it starts? Does taking an anti-inflammatory medication before starting help? How about frequent rest stops and good hydration? Walking sticks? Is ice available for ice packs ? Anything else one can do? Thank you in advance!
