A big toe nail growing into the flesh is usually caused by paronychia or ingrown toenails, which may result from trauma, improper trimming of the toenails, infection, or other factors.
Trauma is a common cause, such as bumping or squeezing injuries, which can damage the tissue around the nail, causing the nail to grow inward instead of normally. Incorrect toenail trimming, such as cutting the nails too short or rounding the corners instead of trimming straight across, as well as wearing tight or narrow shoes, can also place pressure on the toenail, leading to inward growth. Paronychia and fungal infections may also cause nail deformities and changes in growth direction, making the nail more likely to grow inward.
In terms of treatment, mild cases of paronychia can be relieved by soaking the foot in warm water, local disinfection, and proper trimming of the toenail. However, if symptoms are severe—for example, if an abscess develops, there is persistent pain, or fever occurs—prompt medical attention is necessary. A healthcare provider may need to perform professional procedures, such as partially or completely removing the portion of the nail embedded in the skin, and prescribe antibiotics to control the infection.
In daily life, maintaining clean and dry feet, choosing appropriate footwear, and avoiding prolonged wear of high heels or tight shoes can help prevent such conditions.
