Take a close look at the nail. Fungal infections often begin at the nail’s edge and may cause the nail to lift from the nail bed. If discoloration and thickening appear evenly across the nail, a systemic condition like psoriasis may be involved. Measuring nail thickness over time can help you track changes.
2. Simple At-Home Ways to Gauge Severity
You can monitor the condition at home by gently pressing on the nail to see if there’s pain, which may signal deeper involvement. A magnifying glass can help you spot separation, debris, or scaling beneath the nail. Watch for unusual colors such as green or black, which may indicate infection or injury.
Keeping a weekly record of nail color, thickness, and discomfort can help you notice patterns and provide useful information for your doctor later.
3. Keep Feet Dry: Daily Habits That Limit Fungal Growth
Since fungi thrive in moist environments, dryness is key. After bathing, dry your feet thoroughly—especially between the toes. A cool-setting hairdryer can help remove lingering moisture.
