Isn't it amazing how subtle
Isn't it amazing how subtle barefoot running is, not much room for error, diametrically opposed to running in shoes where all sorts of sins are forgiven.
It would be interesting if a whole bunch of Kenyan kids were members of the forum they would be amazed at the difficulties we are having. It shows how far away from nature we have moved.
Looks like rest is the thing you are going to need, also, maybe ice is not the right remedy for the tendon. It is a common mistake that people make. Ice is used to stop blood flowing to an injured area in the case of torn blood vessels. It is not good for tendon problems as you want the opposite, you want blood flooding to the area to speed up the healing process.
The tendons are not well served with blood vessels and I find using warm gel packs around the area would speed up the healing. Ultrasound is basically doing the same thing, warming the tissues and increasing blood flow.
Don't get discouraged, I think that in a years time you will be able to look back the state you are in now and say 'wow, look what I went through'
I would say it is only in this last month that I am 'getting it', after starting barefoot running about 15 months ago, I must be a slow learner.
What I did learn though is that when I got tendon problems like you have it is because of the following:
1. You already have a knee problem, you will favour your other leg and this will cause a running imbalance. Let your injuries settle don't push on through them.
2. My tendon pain came when I got too big headed about my barefoot running, kind of like a slap in the face. I had been pushing off with my toes and along came a warning.
3. My heels always touch the ground, concentrating on keeping your heels off the ground puts a lot of strain on the tendon. Not landing on your heels is what we do but this does not mean our heels don't touch the ground, they will, as a secondary action.
I had a bit of tendon tenderness the other day due to my competitive nature, I don't like our shoed bretherend trying to put me in my place by running past me. Earlier in the week I had to outsprint two runners on a stretch of road, that extra speed caused a bit of tenderness the next day. Fine now.
So, take you time, there is no rush. Champion tennis players or golfers get where they are by being persistant, that is the ability we all need.
good luck.
