Will an Infected Cut Heal on Its Own?
If aninfected cutis left alone without treatment, complications may develop.
Complications
In most cases, healthcare providers willprescribe antibioticsto fight the infection.
Untreated, infected wounds can become serious.
They may develop into cellulitis or an abscess.
Rarely can they lead to sepsis or necrotizing fasciitis.
Cellulitis
Cellulitisis an infection deeper in the skin.
If you develop cellulitis, you will need antibiotics.
Abscesses
Abscessesare pockets of pus.
Your healthcare provider may need to drain the abscess to help it heal.
Depending on how well they can drain and clean the wound, they may or may not prescribe antibiotics.
If an abscess is left untreated, it can lead to a systemic infection.
Necrotizing Fasciitis
Another rare complication that also requires immediate care isnecrotizing fasciitis.
This complication can lead to limb loss and significant scarring from removing the infected tissue.
Medical Treatment
Treatment will depend on the extent of the infection.
A healthcare provider may prescribe oral, IV, or injected antibiotics depending on the severity of the infection.
They may or may not collect cultures to determine which organism is causing the infection.
Some antibiotics are considered broad-spectrum and work against several bacteria, while some are more specific.
Even if yourinfection improvesafter a couple of days, it is essential to complete the entire prescription.
In the case of an abscess, a healthcare provider will likely drain and cover it.
They may pack it, too.
Covering the injury with an adhesive bandage can also help keep the injury clean.
Ensure you change the bandage daily or whenever it gets wet or dirty.
