Hallux valgus is a disorder of the foot in which the hallux or great toe is deflected laterally towards the other or lesser toes, often causing a bony prominence to develop over the medial aspect of the metatarsal head and neck. A bunion is an abnormal bony bump that forms on the joint at the base of the big toe. A Bunion is a bony deformity of the joint at the base of the big toe.
Most of the time, hallux valgus deformity is accompanied by soft tissue enlargement consisting of a fluid-filled sac (called a bursa) under the skin. You may also have heard the Latin term hallux rigidus,” which is a completely different foot condition, that of having a big toe that is stiff with a very limited range of motion. If you notice that your big toe isn't straight and that it is bending toward the toe next to it, this is something that you must not ignore or assume that your big toe will straighten out on its own.
Shoes rubbing against a bunion can cause blisters or open sores that can become infected. Foot infections are particularly dangerous in people with peripheral artery disease or diabetes, who often don't feel pain because their nerves are damaged and don't transmit pain sensations normally. If pain and disability become too difficult to live with, surgery may be required. Bunion surgery usually results in significant reduction in pain and an improvement in appearance, but wearing shoes that are too small or tight can cause bunions to recur, the AAOS warns. Hallux valgus is a progressive foot deformity characterized by a lateral deviation of the hallux with corresponding medial deviation of the first metatarsal. The correction is achieved by a chevron osteotomy.
HV and foot disorders was also associated with altered rearfoot forces, which given prior evidence suggesting forefoot complications are associated with rearfoot disorders, suggests that the rearfoot should be considered in etiology and treatment of HV and forefoot complications. In addition, lower CPEI and higher MAI values were associated with HV, confirming results from studies that have described foot pronation and lower arch structure in feet with HV. Prospective studies are needed to elucidate of the etiology of HV and structural disorders in relation to plantar pressure loading.

The frequency or duration of pain may have recently started to increase, and activity may exacerbate the pain. A patient may present with a deep or sharp pain in the hallux MTP joint on walking, and exacerbation during particular activities. There may be an aching pain in the metatarsal head due to irritation by shoes. There may be a recent increase in the size of the deformity or medial Back Pain bump. Ask about limitation of physical or daily living activities to understand the severity of the pain. A rarer presentation is burning pain or tingling in the dorsal aspect of the bunion, which indicates entrapment neuritis of the medial dorsal cutaneous nerve. Examine the foot whilst bearing weight, although much of the examination will have to be performed whilst not weight bearing.
