Can you please suggest treatments for wound infections?

See your doctor: Physicians can empirically(best guess) treat wounds, but they to do a tissue culture/biopsy is better than a swab culture. Of course one should clean wound, and a doc may need to debride wound. Additionally one would want to cleanse wound regularly, and use appropriate dressing to decrease chance infection or manage bioburden infection if present, oral and IV antibiotics may be necessary.
