What options can i use to help heal infection in a small wound on my leg
For a small infected leg wound, the evidence here says a plain petrolatum ointment may beat antibiotic ointments, and oral antibiotics work as well as IV for simple skin infections.
The most useful finding is from a small randomized trial in 20 adults: Aquaphor, a plain petrolatum-based ointment with no antibiotic, healed laser wounds faster and restored the skin barrier better than Neosporin or Polysporin, with no infections in any group [1]. That suggests the ointment base itself, keeping the wound moist, matters more than the antibiotic. A mouse study also found a plain herbal gel outperformed a commercial antibiotic ointment at closing wounds [2].
For an actual infection, oral cephalexin cured 100% of 104 people with simple skin infections by day 7, matching IV antibiotics [4]. Topical sodium fusidate healed infections in about 7 days versus nearly 10 for oral antibiotics in a 1977 study [3]. But watch for MRSA: in a Hawaii clinic where MRSA is common, cephalexin failed more often than trimethoprim-sulfamethoxazole or clindamycin [5].
The evidence is thin on what to do first. No study here compares cleaning methods, honey, or silver dressings. The trials are small, old, or in mice. None were funded by manufacturers, but none followed patients long-term either.
My call: clean the wound, keep it covered with plain petrolatum ointment, and watch for spreading redness, fever, or worsening pain. If it looks infected, oral antibiotics work; ask about MRSA coverage. Confidence: moderate.

Empiric Outpatient Therapy with Trimethoprim-Sulfamethoxazole, Cephalexin, or Clindamycin for Cellulitis
In a 3-year retrospective outpatient study at a Hawaii medical center, trimethoprim-sulfamethoxazole and clindamycin (active against community-associated MRSA) demonstrated higher cellulitis treatment success than cephalexin, supporting MRSA-active empiric therapy in MRSA-preval…
