Introduction
In general, it is normal for a knee wound to still not have healed 15 days after scabbing. However, delayed healing may also be due to malnutrition, fatigue, exposure to cold, wound infection, or re-injury from repeated abrasion. If you experience any physical discomfort, seek medical attention promptly and follow standardized treatment under a doctor's guidance, which can help promote recovery. It is recommended to consume nutritious foods regularly to supplement the nutrients your body needs.
Generally, if a knee wound has not healed 15 days after scabbing, it may be a normal phenomenon, or it could be due to factors such as malnutrition, fatigue and exposure to cold, wound infection, or re-injury. Different causes require different management approaches. The specific analysis is as follows:
1. Normal condition
After a wound forms a scab, the surface crust will gradually fall off. If it remains in place for over half a month but there are no signs of redness, swelling, or pain, this is usually considered normal and does not require excessive concern. It is recommended that patients maintain good personal hygiene and avoid getting the wound wet to prevent infection.
2. Malnutrition
Poor dietary habits, such as prolonged picky eating or selective eating, may lead to insufficient nutrient intake, which can impair wound healing. It is advisable to consume more nutritious foods to supply essential nutrients the body needs, such as eggs, beef, and other protein-rich foods.
3. Fatigue and exposure to cold
Physical exhaustion and exposure to cold temperatures can also slow down wound recovery. Patients are advised to get adequate rest and protect themselves from cold environments.
4. Wound infection
If wound hygiene is neglected during recovery—for example, frequently touching the wound with bare hands—bacterial infection may occur, prolonging the healing process. Patients may follow medical advice to disinfect the wound using povidone-iodine or hydrogen peroxide to promote healing. In cases of fungal infection, oral antifungal medications such as itraconazole capsules or fluconazole capsules may be prescribed to relieve symptoms.
5. Re-injury (secondary abrasion)
If the wound suffers a secondary abrasion before it is fully healed, this can also delay healing. Any re-injury should be promptly cleaned and disinfected.
If patients experience any discomfort or worsening symptoms, they should seek medical attention promptly and receive standardized treatment under a doctor's guidance to support recovery.
