| Pain In The Ball Of The Foot |
|
Running can exert as much as 110 tons of cumulative force per mile on the five long bones that run from your arch to your toes (the metatarsals). When you push off the ground, your body weight is transferred to the metatarsals.
If the weight distribution across the foot is uneven when it hits the pavement, whether due to foot mechanics, a tight Achilles tendon, calluses, or other causes, the metatarsals can become irritated and inflamed. This results in metatarsal symptoms such as burning, stabbing, or aching pain in the "head" of the bone just beneath the toes. This problem may be treated with ice, rest, and the use of shock-absorbing insoles.
