Hallux valgus, more commonly referred to as a bunion, is a painful bony bump that develops slowly on the inside of the boot at the big toe joint. Pressure on the big toe joint makes the big toe lean toward the second toe. Over time, the normal structure of the foot changes, resulting in hallux valgus. This makes it painful to wear shoes or walk.
The big toe is made up of two joints; the larger of the two is the metatarsophalangeal (MTP) joint, which is where the first long bone of the foot meets the first bone of the toe. This is where hallux valgus develop.
A bunion forms when the bones that make up the MTP joint move out of alignment. The MTP joint gets larger and protrudes from the inside of the forefoot.
They may be caused by wearing poorly fitted shoes, such as heels with a pointed toe, heredity or having an inflammatory condition, such as rheumatoid arthritis. Anyone can develop these bony bumps, but they are more common in women since many women wear tight, narrow shoes that squeeze the toes together.

Your physician will ask you for a complete medical history, your symptoms and conduct a physical examination. An X-ray can confirm the diagnosis.
Usually treatment does not involve surgery, which can help reduce pain and keep the it from worsening; however, it will not reverse the development. Most of the time your physician will recommend a change in footwear, to add padding to your shoes, orthotics, icing or medications.
Bunion surgery is only recommended if other nonsurgical options have not provided relief. Surgery realigns the bone, ligaments, tendons and nerves so that the big toe can be brought back to its correct position. No hospital stay is recommended after surgery. There are many different surgical methods, the best method of surgery is determined after examination.
It may require up to four weeks of non-weight bearing and can take several months after surgery for a complete recovery.
