Overview
A bunion looks like a bump on the inside of the foot where the big toe joins the foot. Over time, the bunion gets worse. The big toe starts to lean toward neighboring toes instead of pointing straight ahead. (The scientific name for this is hallux valgus or hallux abducto valgus.) The bump is a sign that the bones of the foot are out of alignment. While shoes with high heels or pointed toes may cause the joint to ache, they don’t cause bunions. Most often they are due to an inherited foot structure. The tendons and ligaments that hold bones and muscles together at the joint are not working as they should. This structure makes it more likely that a person will develop a bunion.
Causes
Bunions are more common in women than men. The problem can run in families. People born with abnormal bones in their feet are more likely to form a bunion. Wearing narrow-toed, high-heeled shoes may lead to the development of a bunion. The condition may become painful as the bump gets worse. Extra bone and a fluid-filled sac grow at the base of the big toe.
Symptoms
The most common complaint with bunions is pain that develops over the large bump due to shoe pressure. A red, inflamed area can develop, called a bursa. With ongoing pressure, the inflammation can cause throbbing, as it presses against the blood vessels, or swelling in the joint. Shooting pains occur when the swelling presses against the nerve. If left untreated, the constant irritation can lead to arthritis that breaks down the joint, resulting in pain and stiffness.
Diagnosis
Looking at the problem area on the foot is the best way to discover a bunion. If it has the shape characteristic of a bunion, this is the first hint of a problem. The doctor may also look at the shape of your leg, ankle, and foot while you are standing, and check the range of motion of your toe and joints by asking you to move your toes in different directions A closer examination with weight-bearing X-rays helps your doctor examine the actual bone structure at the joint and see how severe the problem is. A doctor may ask about the types of shoes you wear, sports or activities (e.g., ballet) you participate in, and whether or not you have had a recent injury. This information will help determine your treatment.
Non Surgical Treatment
You can try over-the-counter remedies like pads to stop them rubbing, or take painkillers such as paracetamol or ibuprofen if they play up. Devices that fit into your shoe, called orthotics, or splints that you wear at night, can slow the progression of bunions. If these don’t help and the bunion is causing a painful and substantial deformity that?s seriously limiting your footwear, your GP will probably refer you to see a podiatrist, medical professionals who specialise in feet. They can give further advice about non-invasive treatments and also refer you for an operation, either with a podiatric or orthopaedic (bone) surgeon, ultimately the only thing that can correct the gnarly blighters. You can visit a podiatrist privately, which will cost anything from ?140-?200. But Mike O?Neill, spokesperson for the Society of Podiatrists and Chiropodists, suggest always going via your GP, who will know the best qualified. Such is the complexity of the bone structure of the foot, there are more than 130 different surgical procedures for bunions. One person?s op may be very different from another?s, so be wary of sounding out a friend about theirs. 
Surgical Treatment
If conservative treatment doesn’t provide relief from your symptoms, you may need surgery. The goal of bunion surgery is to relieve discomfort by returning your toe to the correct position. There are a number of surgical procedures for bunions, and no one technique is best for every problem. Surgical procedures for bunions might involve removing the swollen tissue from around your big toe joint. Straightening your big toe by removing part of the bone. Realigning the long bone between the back part of your foot and your big toe, to straighten out the abnormal angle in your big toe joint. Joining the bones of your affected joint permanently. It’s possible you may be able to walk on your foot immediately after a bunion procedure. However, full recovery can take weeks to months. To prevent a recurrence, you’ll need to wear proper shoes after recovery. It’s unlikely that you’ll be able to wear narrower shoes after surgery. Surgery isn’t recommended unless a bunion causes you frequent pain or interferes with your daily activities. Talk to your doctor about what you can expect after bunion surgery.
