Foot pain; no swelling, no bruising
(Cincinnati, OH, USA)
I am experiencing pain while walking/running. It is sharp, but comes and goes in severity, sometimes so bad that it causes me to limp, other times hardly noticeable. It is located around my outermost metatarsal of my left foot. The sharp pain goes around the side, bottom and top of that bone. The type of pain is similar to an ankle sprain, but the location of it is strange, I cannot find an common injury on the internet that sounds similar. Peroneal tendonitis is higher, towards the ankle, than where my foot hurts. And a stress fracture on the metatarsal seems unlikely because there is no bruising, swelling, and it doesn't hurt to touch. I ran Monday morning, my longest run to date, and Monday night after getting up from watching some TV the pain started with every step. It lightens up at times and then comes on strong other times. It is some kind of sprain?
The only way you can diagnose a stress fracture is with an xray, you cannot tell my looking at the foot.
In any event it sounds like you may have a bursitis around the fifth metatarsal head which is a fairly common occurrence.
You can try some anti-inflammatory medication, if you can tolerate it, make sure your shoes are not creating too much pressure on the bone.
If that does not help you may need to see a podiatrist in which case a cortisone injection may be in order.
