What to do if your knees itch in summer?

1. When taking a bath, you should choose a mild, preferably slightly acidic shower gel, and avoid using alkaline soaps with too strong cleaning power. Of course, during the treatment period, use less soap or shower gel when bathing to avoid excessive irritation.

2. After bathing, apply moisturizing body lotion immediately before your skin is completely dry, especially to particularly dry areas such as the limbs.

3. Soak your feet in warm water for 10-20 minutes before going to bed and exercise for a while.

4. It may be caused by calcium deficiency. It is recommended that you go to the hospital for a trace element test and pay attention to supplementing calcium, zinc, and vitamin D.

5. Use anti-allergic drugs and hormones. Apply ice compresses when using topical medications, and don't use too much.

6. Do not use hot water or hot compresses as they will aggravate the condition.

7. Do not use wind oil, floral water, and mosquito repellent anymore. If the itching is really unbearable, you can use an ice towel to cool it down. You can also put ice cubes in a plastic bag and apply it. Do not overdo it to prevent frostbite.

8. It is best to see a dermatologist and continue to apply the medicine to eradicate the problem as much as possible, otherwise it will recur frequently in the future. If it is inconvenient to see a doctor, you can go to the pharmacy to buy 999 Dermatitis Cream and apply it. You will feel better in about 3 to 5 days, but you must continue to apply it for a while, otherwise it will be very troublesome once it turns into chronic contact dermatitis.
