A bunion (hallux valgus) is a deformity of the base joint of the big toe. The cause is not clear in many cases. The deformity may cause the foot to rub on shoes, which may cause inflammation and pain. Good footwear is often all that is needed to ease symptoms. An operation to correct the deformity is an option if good footwear does not ease symptoms.
There is some debate about the main cause of foot bunion pain, but they tend to fall into 2 categories. Genetics. There is a definite genetic link, meaning that if someone in your family suffers from a hallux abducto valgus, there is a high chance that you will too, although this is not always the case. It may be due to an abnormal foot position such as flat feet, or a medical condition such as hypermobility (where your joints are overly flexible) or arthritis (e.g. rheumatoid arthritis or gout). Regularly wearing high heels with a pointed toe puts you at high risk for developing foot bunions. Ill-Fitting Footwear. Poorly fitting shoes are thought to be the other common cause of foot bunion pain. Frequent wear of tight fitting shoes or high heels places excessive pressure on the big toe pushing it into the classic hallux abducto valgus position.
Most patients complain of pain directly on the bunion area, within the big toe joint, and/or on the bottom of the foot. The bunion may become irritated, red, warm, swollen and/or callused. The pain may be dull and mild or severe and sharp. The size of the bunion doesn?t necessarily result in more pain. Pain is often made worse by shoes, especially shoes that crowd the toes. While some bunions may result in significant pain, other bunions may not be painful at all.
Although bunions are usually obvious from the pain and unusual shape of the toe, further investigation is often advisable. Your doctor will usually send you for X-rays to determine the extent of the deformity. Blood tests may be advised to see if some type of arthritis could be causing the pain. Based on this evaluation, your doctor can determine whether you need orthopaedic shoes, medication, surgery or other treatment.
Non Surgical Treatment
Padding with a number of different materials (eg felt) to reduce pressure on the painful prominence of the bunion. Physical therapy can be used to help with the symptoms and improve the range of motion (this is particularly helpful if the pain is coming from inside the joint, rather than from shoe pressure). Manipulation of the joint can be used to help with this (manipulation will never correct the alignment of the joint). Any corns and calluses that are causing symptoms should be treated. The correct fitting of footwear is essential for anyone who is serious about doing something about their bunions and hallux valgus. It may be possible to have your shoes stretched over the area of the bunion to also relieve pressure. Foot orthotics may be useful in helping with the instability about the joint. They may be more helpful if there are other symptoms in the foot as well, as their use in "treating" bunions is controversial. They may play a role in slowing progression and in the prevention of bunions developing again after surgical correction. Exercises can be important in maintaining the mobility of the joint in those with bunions, this is especially important for the arthritic type pains that may be originating from inside the joint and for the prevention of these painful symptoms in the future.
Bunionectomy is a general term that describes a variety of bone and soft tissue procedures that are intended to realign your big toe and reduce the prominence at the base of your big toe. The procedures chosen are based on numerous factors, including measured angular displacement of your involved joints (especially your first MTP joint). The degree of pain you are experiencing. The degree of joint dislocation and cartilage damage within your affected joint. Flexibility of your adjacent joints. Flexibility of soft tissues in your problem area.
