I started the ChiRunning book, and adapting my technique while reading through.
Before I would be mostly running on the front of my feet, and I would typically feel my calves after the run. After a good stretch, I would feel fine, and besides that, I would not have any other issues.
Since I started adapting, I now land my feet with a mid-foot strike, and try to focus on relaxing the muscles in my legs, and shoulders, rotate my hips, make sure that my feet land straight, have a straight posture etc.. etc… and I think that I can do most of it.
The problem is that now, I have pains from ankle to knee, feels like inside the leg. I don’t have any muscle cramps or soreness, so I must be doing something right, but the pain is such that I’m seriously thinking about going back to my old running style. I don’t want to because everything else is improving, and I’m looking at doing a half or full marathon sometime in the future.
Today I ran a 5K in 27min, so nothing fancy. I have no idea of what the muscles or tendons are called, so you’ll have to imagine 
but basically it feels a little like shin splints, combined with pains below the calves, mostly on my left leg.
I also feel a little soreness on the opposite side on the hip, just about where the bone sticks out, and it’s probably related.
I’m probably going to see my doctor, and I want to be able to chi-run, any idea of what this could be? I feel that I can probably correct this by myself, the obvious answer being “go see a chi-running trainer”.
Any hints?
I regularly run 5Ks and 10Ks without tremendous effort.
thanks
