The second toe shows symptoms of swelling and pain for several common reasons: first, toe trauma, which can occur during exercise, and heavy object smashing can also lead to injury to the toe. Patients will show local swelling and pain, and toe joints will also have obvious restrictions on movement, and serious cases will damage the skin, making local open injuries. Second, bunion deformity, the bunion tilted to the lateral side will jack up the second toe, presenting the appearance of a mallet toe. The elevated toe is subject to severe friction from shoes, and prolonged uncorrected bunions can cause soft tissue damage to the second toe, which can result in swelling and painful toe symptoms, as well as a very pronounced local mallet toe appearance.
