The best thing to say about the natural history of bunions is that they are unpredictable. This is both in terms of whether the bunion deformity will progress, and also whether the bunion will become painful (if it is not already painful). It would probably however be true to say that once a previously painfree bunion has started to become painful it is not common for the bunion to go back to being entirely pain-free.
Bunions, Corns, and Calluses are all related in that they can each be caused by tight and/or poor fitting footwear. Each can also be caused by the following, footwear that is too narrow and/or too small. Constrictive toe boxes (toe area). Tapered toe boxes can cause bunions and cause them to worsen to the point of needing surgery.
Your bunion may not cause any symptoms. Or you may have pain in your big toe, red or irritated skin over the bunion, and swelling at the base of the big toe. The big toe may point toward the other toes and cause problems in other toes, such as hammer toe . A bunionette can cause similar symptoms at the base of the little toe.
X-rays are the best way to determine the amount of deformity of the MTP joint. Blood work may be required to rule out other diseases that may be associated with bunions such as rheumatoid arthritis. Other tests such as bone scans or MRI's are not usually required.
Non Surgical Treatment
Treatment falls into two broad categories, conservative and surgical. From a conservative standpoint, efforts are directed at correcting faulty foot mechanics with custom molded insoles and relief of symptoms. These include Custom Orthosis to stabilize the abnormal motion of the hind and fore foot. Shoe gear modification: Using shoes with larger toe boxed and more supple materials. Changes in activities. Try to avoid those things which cause symptoms. Anti-inflammatory medication for periodic relief this includes cortisone injections into the joint as well as oral medication.
Surgery can be a very successful treatment for bunions and could be considered if you are having pain that is affecting your function on a regular basis, for instance, pain during sports or wearing work shoes. It is important, however, that you are seen by a consultant orthopaedic foot and ankle surgeon who has undergone specialist training with a foot and ankle fellowship. There are many different surgical techniques and it is important that your surgeon is expert in several of these so that you have the one that is best for your unique deformity. Bunion removal is usually done under general anesthesia. This means you will be asleep throughout the procedure. The operation can be performed as a day-case, but an overnight stay in hospital is sometimes required. Your surgeon will explain the benefits and risks of having bunion surgery, and will also discuss the alternatives treatments.
