Last time I covered some basic facts about the rings: 1  They're not solid, but rather are composed of chunks of water ice, ranging from the size of an automobile or small building down to the an inch or smaller (including some microscopic dust). 2  The rings are very thin -- maybe just 100 yards or so in thickness.
A bunion (hallux valgus) is a deformity of the base joint of the big toe. The cause is not clear in many cases. The deformity may cause the foot to rub on shoes, which may cause inflammation and pain. Good footwear is often all that is needed to ease symptoms.
Other Causes of Hallux Limitus. 1  Acute trauma to the big toe joint, such as a fracture. 2  Repetitive trauma to the big toe joint -- such as turf toe, which is a common overuse injury in sports. 3  Inflammatory conditions, such as rheumatoid arthritis, psoriatic arthritis, or gout.
