Pus under the nail usually does not heal on its own, and pus under the nail indicates a more serious infection. In this case, if you are not in a condition to receive treatment and have a strong resistance, it may gradually heal on its own. However, in most cases, it may lead to expansion of the infection.
Most of the time, pus under the nail is considered to be caused by puncture wounds, ingrown nails, embedded nails or the spread of onychomycosis. In this case, if there is no convenient treatment and the patient has a strong resistance, it may heal slowly, but this is rare.
If pus under the nail is not treated in time, most patients may experience an expansion of the infected area, and with the gradual multiplication of germs, the pus may progress to the deeper part of the nail, resulting in purulent dactylitis, which leads to severe pain at the end of the finger, osteomyelitis, and even necrosis at the end of the finger.
Therefore, no matter what the cause of pus under the nail, once found, it is recommended to consult a doctor in time and follow the doctor’s instructions for treatment.
