Hi. As per your case history of bed sores. My treatment advice is - 1. Avoid pressure on the affected part. 2. Apply a mild antibiotic cream like fusiderm cream twice daily on it. 3. Other treatment options are oral antibiotics like levofloxacin, cefadroxil and azithromycin taken only after consulting a dermatologist. Thanks. Dr. Harshit bhachech. MBBS, DDVL.
