Take care of the skin around your nails and avoid any damage to them. Nails should not be cut too short, and you should not pull out "hangnails" with your hands. This is one of the things to pay attention to when it comes to paronychia.

2. Take precautions before they happen. Wood thorns, bamboo thorns, sewing needles, fish bone spurs, etc. are the foreign objects most likely to puncture the nail groove in daily life. You should be extra careful when participating in labor or busy with housework.

3. Pay attention to the maintenance of your fingers at ordinary times. Apply some Vaseline or skin care ointment after washing your hands and before going to bed, which can enhance the disease resistance of the skin around the nail groove.

4. When there is a slight injury on the finger, you can apply 2% iodine and wrap it with a band-aid to prevent infection. This is also a point of attention for paronychia.

5. In the early stage of paronychia, hot compresses, physical therapy, external application of Ichthyose ointment or Sanhuang powder can be used, and sulfa drugs or antibiotics can be taken if necessary.
