Patient's question:
I am a 72-year-old diabetic this year, and I have had the disease for many years. Recently, my fingernails and toenails have developed ulcers. What could be the cause? Which medications should I use:Doctor's answer:
Paronychia, also known as onychomycosis, is an infectious condition of the tissues surrounding the nail caused by minor local trauma. Initially, it presents with redness and severe pain on one side of the nail or at the nail root. Over time, it may develop into pus, forming an subungual abscess under the nail. If it ruptures, poor drainage often leads to chronic inflammation.Treatment Suggestions:
1. Mix 1 gram each of green tea leaves, black sesame seeds, and fine salt with a small amount of physiological saline, then mash them into a paste. After routine skin disinfection, apply the mixture to the affected area of paronychia. Change the dressing once daily for 2 to 4 consecutive applications. Avoid getting the treated area wet during the application period.
2. Take equal parts of Huanglian (Coptis chinensis) and Da Huang (Rhubarb) and pick out any impurities. Dry them, then grind them into a fine powder for storage. When using, mix the powder evenly with vinegar (dilute the vinegar if for children) and apply it externally to the affected area. Clean and replace the dressing daily.
