If you?ve developed a solid bump at the base of your big toe along with pain and swelling, it?s possible that you have a bunion. According to the American Podiatric Medical Association (APMA) A bunion is an enlargement of the joint at the base of the big toe-the metatarsophalangeal (MTP) joint, that forms when the bone or tissue at the big toe joint moves out of place. This forces the toe to bend toward the others, causing an often painful lump of bone on the foot. Since this joint carries a lot of the body?s weight while walking, bunions can cause extreme pain if left untreated. The MTP joint itself may become stiff and sore, making even the wearing of shoes difficult or impossible. Bunions, from the Latin ?bunio,? meaning enlargement, can also occur on the outside of the foot along the little toe, where it is called a ?bunionette? or ?tailor?s bunion.?
Contributing factors may include excessive foot pronation, wearing tight and pointed-toe shoes, and occasionally trauma. Joint misalignment causes osteoarthritis with cartilage erosion and exostosis formation, resulting in joint motion being limited (hallux limitus) or eliminated (hallux rigidus). In late stages, synovitis occurs, causing joint swelling. In reaction to pressure from tight shoes, an adventitious bursa can develop medial to the joint prominence, which can become painful, swollen, and inflamed.
The skin over your big toe may be red and tender. Wearing any type of shoe may be painful. This joint flexes with every step you take. Your big toe may angle toward your second toe, or even move all the way under it. The skin on the bottom of your foot may become thicker and painful. Pressure from your big toe may force your second toe out of alignment, sometimes overlapping your third toe. If this condition gets severe, it may be difficult to walk. Your pain may become chronic and you may develop arthritis.
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.
Non Surgical Treatment
When the deformity is mild, treatment is usually not necessary. However, changing shoes to ones that have little or no heel, and are wider in the toe area (toe box) will be more comfortable and may help to prevent worsening of the bunion deformity. If the bunion starts to become painful, other measures may help. Bunions can cause pain in several different areas. The medial eminence may be painful, the entire first toe joint may hurt, or there may be pain underneath some or all of the forefoot (the ball of the foot). Pain over the medial eminence is the most common problem that affects bunion patients. A ?toe spacer? can be placed between the first and second toes and can provide some pain relief as it straightens out the bunion slightly. Pads placed over the medial eminence itself are hard to keep in place and rarely help to relieve pain. Pain underneath the first toe or lesser toes can be relieved by pads placed in the shoes in precise areas. The pads help to take pressure off the prominent areas on the bottom of the foot. Generalized measures to relieve bunion pain, such as physical therapy or foot stretching exercises, have not been shown to be helpful. Orthotics are often prescribed, but are also rarely helpful in relieving pain over the bunion, but may help with pain felt under the ball of the foot.
Surgical options, such as a bunionectomy, can remove the bunion and realign the toe. There are several types of surgeries to fix the bunion. The type of bunion you have along with other factors such as the degree of severity and underlying cause of the bunion will determine which approach would be most beneficial for you.
