Why is the palm of my left hand itchy?

Itchy palms can be caused by a variety of things. Allergies, eczema, contact dermatitis, and even psychological causes can all contribute to itchy palms.

Allergies can cause itchy palms if you are exposed to something you are allergic to. Common allergens include dust, pollen, pet dander, and certain foods. If your left palm is itchy, you may want to consider whether you have been exposed to anything that could be causing an allergic reaction.

Eczema is a common skin condition that can cause itchy palms. Eczema is a chronic condition that causes red, itchy, and inflamed patches of skin. If you have eczema, your left palm may be itchy due to inflammation and dryness.

Contact dermatitis is a skin reaction that occurs when you come into contact with an irritant. Common irritants include soaps, detergents, and other chemicals. If your left palm is itchy, it may be due to contact dermatitis.

Finally, psychological causes can also contribute to itchy palms. Stress and anxiety can cause your body to produce more histamine, which can lead to itching. If you have been feeling particularly stressed or anxious lately, it may be the cause of your itchy left palm.

If your left palm is itchy, it is best to consult a doctor for a proper diagnosis. They will be able to determine the cause of your itching and provide you with the best treatment options.
