As I mentioned yesterday, I had been having some pain in my foot. I had a chiropractor appointment for my back anyway and I asked him about my foot. I showed him the point of pain and sure enough it was my navicular.
Location of the navicular:
In technical terms: "This bone is situated on the medial side of the foot and forms a proximal articulation with the talus and distal articulation with all the cuneiform bones. It may occasionally be articulated laterally with the human cuboid bone." (source)
And then my preferred way-pictures:
"It is an important part of the human medial longitudinal arch, which is the highest among the three arches of the foot. This arch plays a significant role in the even distribution of body weight through the bones in the foot. The bone also helps to hold the arteries running through the foot." (source)
So basically what had happened is my navicular had popped out of place and was causing stress on my arch and my ankle and calf felt weak and was causing my right foot to overpronate. My chiropractor said that it can pop out of place quite easily, but is popped back in easily. As soon as he was done he had me walk around to make sure everything felt fine and immediately I noticed a difference. My foot felt more stable and I didn't feel as much stress on my ankle.
I can't say for sure when this happened, but according to what I read about The Essex Runner's experience it can be caused by shoes that are too narrow or shoes that are tied too tightly. It seems that I have a fairly high arch and sometimes I have problems getting the lacing over my instep comfortable. I ran for the first month after I started running postpartum in too small, worn out shoes or it could have happened during pregnancy when everything is looser than normal due to the relaxin.
Stress fractures of the navicular seem quite common according to my google search, but I had ruled that out in my head already, because my navicular on both feet were sore although the right much more than the left.
I'm running today for the first time since a week ago yesterday. I hope that my rest will have gotten my aches and pains under control enough because I have a race July 13 and I want to be a least somewhat prepared.
What was your last injury? What did the treatment look like?
Do you ever see a chiropractor?
