Eczema on the shoulder is mostly thought to be related to the patient’s own allergy-prone constitution. In Chinese medicine, it is also considered to be related to the dampness and heat of one’s own blood. Therefore, it is recommended that patients should go to the hospital for allergen testing and targeted desensitization treatment. Usually, one should also pay attention to substances that cause allergies, such as eating irritating foods, especially seafood, such as shrimp, crabs, oysters, shells, etc., which should be avoided. The diet should be light and easy to digest, with more fresh vegetables and fruits. Also, avoid staying up late at night as well as preventing constipation. Anti-allergic drugs such as cetirizine, loratadine, etc. can be given as treatment. However, specific treatment is recommended to be carried out under the guidance of a clinician.
