Fingernails that hurt when pressed may be caused by nails that are too short or foreign objects that are pierced into them, or they may be caused by onychomycosis, swellings under the skin, localized infections, and so on.
1. Nails are too short: when the nails are cut too short, it will make the surrounding tissues feel uncomfortable, and it will be easier to feel pain when the fingers are pressed.
2. Stabbing foreign objects: When a tiny foreign object is stabbed into the finger, it may not be noticed, and when it is pressed, it will cause pain due to the extrusion factor.
3. Nail groove inflammation: Nail groove inflammation is often caused by infection of some minor injuries, which can cause pain when the finger is pressed.
4. Subcutaneous swelling: such as hemangioma, after pressure due to smooth muscle contraction or muscle contraction, will cause obvious pain.
5. Localized infections: when the tip of the finger is infected, there will also be pain, and if it is not treated in time, there may also be pus.
It is recommended that if the symptoms persist or worsen, consult a doctor for targeted treatment under the guidance of the doctor.
