The possible causes of bunion foot bone inflection pain are bunion, bunionitis, big toe metatarsophalangeal arthritis and gout etc.
1. Bunion: also known as hallux valgus, the most common cause of bunion foot abduction pain. As the bunion is tilted outward, the first metatarsal bone is inwardly retracted, resulting in redness, swelling and inflammation, bursitis, pain, and so on.
2. Bunion: A sterile inflammation of the bursa on the inside of the metatarsophalangeal joint of the thumb, mostly caused by prolonged pressure on the thumb or internal rotation of the foot, which can cause redness, swelling, pain and deformity of the joints of the metatarsophalangeal joints.
3. Bunion metatarsophalangeal arthritis: long-term arthritis leads to osteophytes at the metatarsophalangeal joints, which irritate the bones of the big toe and cause pain.
4. Gout: Synovial lesions of the joints caused mainly by high purine concentration and content in the blood. Bunion attacks are predominant and can manifest as bunion foot bone abduction pain.
The causes of bunion pain are complex, so it is advisable to go to the hospital to find out the cause.
