Introduction
Causes of thickened toenails growing into the flesh include improper nail trimming, ill-fitting shoes, obesity, or edema. In addition, it could also be caused by paronychia. It is important to note that if a toenail becomes thickened and starts growing into the skin, you should not cut the nail yourself or pull on it forcefully, as this may worsen symptoms or lead to infection. It is recommended to seek medical attention promptly for diagnosis and treatment by a qualified healthcare professional.
Causes of thickened toenails growing into the flesh include improper nail trimming, ill-fitting shoes, obesity, or edema.
1. Improper nail trimming
When a toenail is cut too short, the center may grow faster than the sides, causing granulation tissue to grow forward. The central portion of the nail may then grow outward, leading to the nail thickening and penetrating the surrounding skin. This can also result in redness, swelling, pus formation, and discharge. When trimming toenails, it's important to maintain an appropriate length—neither too long nor too short.
2. Ill-fitting shoes
If the feet are large but the shoes are too narrow or too small, excessive pressure is placed on the toes. Over time, this pressure can cause nail deformities. A deformed nail may continue to grow abnormally and eventually pierce into the soft tissue. It is recommended to wear properly fitting shoes and regularly change socks to prevent bacterial growth.
3. Obesity or edema
If a person has recently consumed excessive calories or experiences abnormal water metabolism, resulting in obesity or swelling of the feet, the toenail may be forced inward, leading to ingrown nails (onychocryptosis). In severe cases, surgical treatment such as partial or complete removal of the nail plate or nail bed may be considered under medical supervision.
In addition, this condition may also be caused by paronychia. It is important to note that if a toenail becomes thickened and starts growing into the flesh, one should not attempt to trim it aggressively or pull at it, as this may worsen symptoms or lead to infection. Prompt medical attention is advised for proper diagnosis and treatment by a healthcare professional.
