A few days ago I consulted a sports podiatrist. I knew that I had pronation in my feet, but did not know the potential consequences, probably because I thought pronation meant flat feet. I don't have flat feet, it turns out.
A thorough examination, photos, videos, manipulation ...
My legs are out of alignment. One is 3mm longer than the other. Bones in one heel are not seated in their socket correctly. Same with both hips. Undue pressure on my knees due to improper alignment of upper and lower leg - twisted. And so on. I ought to be in much more pain than I am, particularly as I am nearly 70 y.o. and have walked a lot of Caminos.
Pain in my feet, but very slight. Stiffness and soreness in my ankles, but very slight and only occasional. Aching knees, again slight and occasional. Starting to get pain in my hips, lower back ...
All of the above is caused by the pronation. I was assured that improvements were very possible with manipulation over a few months and orthotics. I could avoid further damage and the need for knee and hip replacements down the track. If I did nothing it was very likely that my problems would get worse, and this could be avoided.
So, I would recommend anyone on this forum who has pronation and has done nothing about it: GO AND SEE A PODIATRIST.
