Why does the knee feel burning after applying a medicated plaster?
Generally, a burning pain after applying a medicated plaster on the knee may be caused by skin sensitivity, drug reaction, skin damage, folliculitis, wound infection, or other reasons. If discomfort occurs, seek medical attention promptly. Detailed analysis is as follows:
1. Skin Sensitivity
Some individuals are sensitive to ingredients in medicated plasters, especially products containing capsaicin or similar components, which may irritate skin nerve endings, causing a burning sensation. Discontinue use of the plaster immediately, wash the affected area with warm water, and apply a cold compress to reduce inflammation.
2. Drug Reaction
Certain medicated plasters contain ingredients with warming effects, such as camphor. A mild sensation of heat after application is considered a normal drug reaction and generally not a cause for concern. This reaction typically subsides gradually and requires no special treatment.
3. Skin Damage
If there are pre-existing minor wounds or skin damage on the knee before applying the plaster, the medication and adhesive components in the plaster might further irritate the damaged skin, causing pain. Clean the wound and avoid reusing the plaster.
4. Folliculitis
Reduced immunity and wearing tight clothing may increase the risk of folliculitis. If folliculitis already exists on the knee, applying a medicated plaster might worsen the inflammatory response, causing a burning sensation, accompanied by severe itching and dry skin. Patients should follow medical advice to use medications such as fusidic acid cream, calamine lotion, or ketoconazole shampoo for treatment.
5. Wound Infection
If there is pre-existing skin damage or a wound on the knee, applying a medicated plaster may lead to bacterial invasion, causing wound infection and pain, which may be accompanied by symptoms such as swelling and fever. It is recommended to follow medical advice and use medications such as erythromycin ointment, mupirocin ointment, or amoxicillin capsules for treatment.
In daily life, it is recommended to consume more foods rich in calcium, phosphorus, protein, and other nutrients, such as milk, eggs, and fish, which help maintain bone and joint health.
