Feet and bunions
A crooked big toe (hallux valgus) is also called a bunion, which occurs when the bones in the big toe slowly move outwards. This causes the big toe to start pointing towards the other toes on the foot, or in some cases, to go over the other toes.
The bunion can cause great pain, and osteoarthritis can occur in the joint over time. Many also have other changes and misalignments in their feet, such as flat feet, where the arches of the foot are flattened out - or hollow feet - where you are born with a very high arch. Often you have the combination of hammer toes, bunions and flat feet.
You will experience soreness and pain in your other toes and in your arch when you have a crooked big toe. You unconsciously change the way you walk when you have pain, and it can give rise to pain elsewhere due to changed load.
Our big toe is our "joystick" when walking, and it should preferably be as straight as possible. We are naturally born with a nice foot-shaped form. The big toe has an important job in making our gait a more "fluid movement", so that the knees, hips and back can help to promote a normal gait.
