Itchy skin, especially on the legs, can be a frustrating and uncomfortable condition. Based on your description, it seems that you are experiencing persistent itching and the development of red spots on your lower legs and upper thighs. This could be attributed to several factors, including dry skin, eczema, or even allergic reactions.
Firstly, the change in weather, particularly during colder months, can lead to dry skin, which is a common cause of itching. When the skin loses moisture, it can become rough, flaky, and itchy. Even if you are using moisturizing creams or lotions, they may not be sufficient if applied only after the skin has already dried out. It is essential to apply moisturizers regularly, ideally right after bathing when the skin is still damp, to lock in moisture.
Another possibility is that you may be experiencing a form of eczema, which can manifest as itchy, inflamed skin. Eczema can be exacerbated by environmental factors such as cold weather, low humidity, and irritants like soaps or detergents. If you have a history of skin conditions, it is possible that your skin is reacting to these changes.
Additionally, the red spots you mentioned could be a result of scratching, which can lead to a secondary infection or inflammation. When the skin is scratched, it can become more irritated and may develop into a condition known as "prurigo," where small bumps form due to chronic scratching.
To address your symptoms, consider the following steps:
1. Moisturize Frequently: Use a thick, emollient moisturizer multiple times a day, especially after bathing. Look for products that contain ingredients like ceramides, glycerin, or hyaluronic acid, which are effective in retaining moisture.

2. Avoid Hot Showers: Hot water can strip the skin of its natural oils, leading to further dryness. Opt for lukewarm water instead and limit your shower time.

3. Use Gentle Cleansers: Avoid harsh soaps and opt for gentle, fragrance-free cleansers that are less likely to irritate your skin.

4. Consider Topical Treatments: If the itching persists, over-the-counter hydrocortisone cream may help reduce inflammation and itching. However, it is essential to use it sparingly and not for extended periods without consulting a healthcare professional.

5. Identify Triggers: Keep a diary of your symptoms and any potential triggers, such as specific foods, fabrics, or environmental factors. This can help you identify and avoid irritants.

6. Consult a Dermatologist: If your symptoms do not improve with these measures, it may be beneficial to consult a dermatologist. They can provide a more accurate diagnosis and may prescribe stronger topical steroids or other treatments tailored to your condition.

7. Avoid Scratching: Although it can be difficult, try to avoid scratching the affected areas. Consider wearing gloves at night to prevent scratching while you sleep.

8. Stay Hydrated: Drink plenty of water to help keep your skin hydrated from the inside out.

In summary, persistent itching and the development of red spots on your legs can be attributed to various factors, including dry skin and eczema. Implementing a consistent skincare routine, avoiding irritants, and consulting a healthcare professional if symptoms persist are essential steps in managing your condition. Remember, your skin health is crucial, and addressing these issues early can prevent further complications.
