Why am I experiencing itching on my legs?

It's important to see a dermatologist. Skin type sensitive or oily? Acne or rosacea? These details are required for treatment. Avoid harsh products and over-washing. Use gentle cleansers and moisturizers. Sunscreen is a must. Avoid touching face. Treat underlying health issues. Eat healthy, stay hydrated. 

Head lice are little bugs that reside in your hair and give you an itch. The nits are the ovum of their species. Treating head lice is crucial to prevent the occurrence of new infections. Ivermectin tablets are an effective treatment although you should consult your doctor first. Shampoos are some of the over-the-counter treatments that may also be effective. The washing of clothing and bedding is necessary to avoid a second infestation. 

The dark circles under your eyes can be annoying. The reasons might be lack of sleep, stress, or even allergies. However, rubbing your eyes a lot can also be the reason. Try sleep management, stress management, and not rubbing your eyes for a while. You can use cold compresses or eye cream as well.

You may have a condition called night sweats which might contribute to the effect of various factors, including anxiety, hormonal changes, or infections. Firstly, try to keep the room cool and comfortable at night, wear light pajamas, and don't consume caffeine before sleeping. In the morning, take clear water as much as your body can accommodate; this will keep the hydrated fluid in your body.
