It is common for a scraped knee to form a hard scab and experience pulling pain during the healing process, which lasts for 17 days.

Excessive exudate from the wound may dry and form a thick scab, causing discomfort when the knee joint moves and the scab pulls on the surrounding newly formed tissue. Alternatively, improper wound management during the early stages might have caused a stronger inflammatory response, affecting the normal healing process beneath the scab.

It is recommended not to forcibly peel off the scab to avoid secondary injury and infection. Instead, moisten sterile gauze with normal saline and gently apply it to the scab for 15–20 minutes, 2–3 times daily, to soften the scab and alleviate pain. Additionally, minimize extensive movements of the knee joint to prevent excessive stretching of the wound.

Monitor the wound area for signs of infection such as redness, swelling, or discharge. If these occur, seek medical attention promptly, as oral antibiotics under a doctor's guidance may be necessary. If the area around the scab itches, avoid scratching; gently tapping the area may provide relief. Regarding diet, increase your intake of protein- and vitamin-rich foods, such as lean meats, fruits, and vegetables, to support wound healing.
