If you're talking foot/leg pain, see a podiatrist. Foot problems are very common, and you may be able to get a lot of relief with simple orthotics.
Now my pains are gluteus and calf related, but I think they are mainly because I have been pushing myself pretty hard. Gotta slow down a bit and give myself more time to recover.
I've known about my alignment issues for years - mega tight hamstrings and weak gluteals so I got my first pair of (corrective) running shoes from a local, reputable, running shop[2] after a gait analysis. I couldn't run further than 3 miles before the pain in my knee became too much.
The shop then referred me to a podiatrist and switched my corrective shoes for a neutral pair, with insoles from the podiatrist. Since then I've had no problems and have run a half-marathon and 10k.
[1] Not that I'm an especially experienced runner but I've known about my alignment issues for years and, with running in particular, really notice the difference the right correction makes.
I do weight training too, but running is a totally different feeling, before I used to force myself to go for runs but now it takes a lot to stop me to go for a run. Its hard to explain, its like I am addicted to it, even though its still painful, but I am recovering much much faster.
I too recommend everyone to give running a try, if you can through the initial hurdle, I don't think you will ever regret it.
Just today, I also finished reading "born to run", while I understand that there are exaggerations in the story to make it more interesting for the readers, and science of "born to run" is still 'up there' and perhaps debatable depending on who you ask, its still one of the best book I have read. Highly recommended to read.
