Introduction
Purple discoloration of the fingernails may be related to trauma, circulatory disorders, systemic lupus erythematosus, and other causes. It can be treated through general measures or medications. Nail discoloration could result from impaired circulation due to constriction of the fingers. Additionally, purple fingernails may also be associated with anemia or infections. After a hospital examination, appropriate treatment can be provided based on the specific symptoms.
Purple discoloration of the fingernails may be related to factors such as trauma, circulatory disorders, or systemic lupus erythematosus. Treatment can involve general measures or medications. Specific analyses are as follows:
1. Trauma
If the fingernail is subjected to external pressure due to inattention, it may easily cause rupture of capillaries at the fingertip, leading to purple discoloration of the nail. In mild cases, cold compresses can help constrict blood vessels and relieve symptoms.
2. Circulatory Disorders
Purple fingernails may result from impaired blood circulation caused by constriction or tightness around the fingers. When circulation is compromised, blood supply to the fingers decreases, leading to reduced oxygen levels and resulting in a bluish-purple discoloration. Symptoms generally improve once the circulatory obstruction is relieved.
3. Systemic Lupus Erythematosus (SLE)
Systemic lupus erythematosus is an autoimmune disease that affects blood flow throughout the body, potentially causing purple fingernails. In more severe cases, medications such as hydroxychloroquine tablets, amoxicillin enteric-coated capsules, or methylprednisolone tablets may be prescribed under a doctor's guidance.
In addition, purple fingernails may also be associated with conditions such as anemia or infections. It is recommended to seek medical evaluation at a hospital and receive appropriate treatment based on specific diagnoses.
