What's wrong with dark purple nails

Dark purple nails may be caused by trauma or insufficient blood supply. It may also be a nail matrix nevus.

1. Trauma: When the fingernails are hit or squeezed by external force, it may cause bleeding in the capillaries under the nail bed, and may also cause the nails to turn black or purple, accompanied by swelling and pain. Generally, these symptoms will gradually ease after a period of rest. If the symptoms are more serious, they can be treated with oral blood-activating and blood-stasis-removing drugs, such as Panax notoginseng tablets.

2. Insufficient blood supply: When the weather is cold, there may be insufficient blood supply to the arms, and it may also cause poor local blood circulation, resulting in black nails. Appropriate local acupuncture and massage can accelerate local blood circulation and metabolism, and also help improve the purple condition of the nails.

3. Nail matrix nevus: Nail matrix nevus is a lesion that grows on the nail. It will cause the nail to turn black and form black lines on the nail. If not treated in time, there is a risk of malignant transformation. Generally, surgical resection is required to relieve symptoms and prevent them from getting worse.
