Metatarsalgia
Pain in the ball of the foot, this is often described by patients as walking on pebbles, this is particularly worse whilst walking or standing.
A number of different causes can cause this condition, such as badly fitting footwear, being overweight and certain medical conditions like Arthritis. People that wear high heels are more susceptable to this which will put increase pressure on the metatarsal heads (toe joints).
Wearing appropriate footwear and the use of cushoning orthoses/insoles will help greatly with this condition.
