Which term describes the condition where the nail grows inward and causes pain?

The term that describes the condition where the nail grows inward and causes pain is "Ingrown nail." This condition typically occurs when the edge of the nail grows into the surrounding skin, leading to discomfort, swelling, and sometimes infection. It commonly affects the toes, particularly the big toe, and can result from improper nail trimming, tight footwear, or trauma to the nail area. Timely treatment is essential to alleviate pain and prevent complications, and in some cases, medical intervention may be required to remove the ingrown portion of the nail. Understanding this condition is crucial for nail technicians, as they may encounter clients with ingrown nails and need to know how to advise them appropriately.
