Nail Trouble: Splitting and Chipping
A 67-year-old woman shares her concern about her nails. She leads a healthy lifestyle, refraining from smoking, alcohol, or coffee consumption, and only takes supplements including calcium, vitamin D, and a multivitamin on occasion. Recently, she has noticed that her fingernails are not only splitting but also breaking frequently. Given that she has avoided manicures due to nail buffing, which further weakens her thin nails, she has taken to researching potential dietary deficiencies but found none. Another thought that comes to mind is her extensive gardening in a warm climate, which may be affecting her nails due to excess moisture. She wonders if there are other contributors to this issue, especially living in a hot and humid region of Florida.

It sounds like you're experiencing persistent nail splitting and breaking, which can be frustrating. Several factors could contribute to this issue, including hydration, environmental conditions, and nutritional aspects. Let’s explore these possibilities and suggest actionable steps to help improve your nail health.
Explanation
Nail splitting and chipping can be caused by various reasons, including:
- Humidity and Moisture: Excessive exposure to moisture, especially in warm climates like Florida, can weaken nails. Gardening can lead to constant wetting of your hands, which might contribute to their condition.
- Nutritional Deficiencies: Even if you haven't found deficiencies in your research, nails need certain vitamins and minerals (like biotin, zinc, and protein) for strength and growth.
- Physical Damage: Activities like gardening can lead to physical trauma to the nails, making them more prone to breaking.
Actionable Next Steps
-
Moisture Control: After gardening or washing your hands, dry your nails thoroughly. Consider using a hand moisturizer or cuticle oil regularly to keep nails hydrated and prevent brittleness. A product containing vitamin E or lanolin may be particularly beneficial.
-
Nail Protection: Use gloves when gardening or doing household chores to protect your nails from excess moisture and physical damage.
-
Dietary Consideration: Although you mentioned researching nutritional deficiencies, consider incorporating more foods high in biotin (like eggs, nuts, and whole grains) and protein (like lean meats and beans) to support nail health. You might also look into a dedicated biotin supplement, which is often recommended for nail strength.
-
Limit Exposure to Water: Try to reduce prolonged exposure to water when possible, and take care to keep your nails dry. Consider using a mild soap that is less drying to prevent damage.
-
Regular Nail Care: Rather than buffing, keep your nails trimmed and shaped to reduce the risk of snagging and breaking. Avoid using harsh chemicals from nail products.
By following these steps, you should be able to see some improvement in your nails over time. Remember, changes won't happen overnight, and it may take several weeks to notice a difference. If the condition persists or worsens, you might consider further investigation into potential underlying issues.

Daily Flush of Heat in Right Ear
I'm a 20-year-old male, and I've been experiencing a strange occurrence with my right ear. Every day, for approximately 20 minutes, it turns intensely red and feels unusually warm. This has persisted for roughly a week. Interestingly, I recall having a similar issue a few years back with one of my heels, where it would swell up, turn red, and sting. At that time, I was diagnosed with depression and anxiety, but that's where the concerns ended.
Misaligned Toenails: Seeking Solutions
I've noticed that my toenails tend to grow at an odd angle, leaning to one side rather than extending straight out. While this condition doesn't cause me any pain, it does bother me quite a bit. I'm curious if there are any methods that could help them grow in a more typical manner. Recently, I began using barefoot shoes—will this change potentially help correct their alignment over time? This issue has persisted for several years and affects both of my feet, particularly the middle toes, where the deviation is most pronounced. My medical history is clear; I don’t take any regular medications, I don’t smoke, and my height is 5'6" while weighing approximately 200 pounds.
Caffeine and Melatonin Effects
15F / I have autism along with a learning disability / asthma / I’m not on any medications I experience significant fatigue whenever I consume caffeine, to the extent that I almost fainted in a field once. I’ve heard this reaction can occur in neurodivergent individuals. Interestingly, I recently found that taking melatonin boosts my energy levels instead; even a tiny dose makes me tremble uncontrollably. I haven't encountered much information regarding this phenomenon. Should I consult a doctor about it?
Concerns About Red Area on Lip
I’m seeking advice about a concerning issue with my lip. I’m a 27-year-old female, and for the last three to four weeks, I've noticed a red patch on the left side of my upper lip that has a numb sensation. Recently, I've observed that this spot seems to have increased in size and has slightly extended beyond the normal outline of my lip. This week, it has also experienced minor peeling, similar to the usual dryness one might see on lips; I inadvertently removed a bit of skin, but it was minimal. While it hasn't developed blisters and remains flat, the peculiar sensation and the slight peeling this week are troubling. The emergence of this spot seemed sudden; I only noticed it one day when an area of my lip felt unusual, though initially, I didn’t dwell on it. At present, the area is smaller than a dime and is not easily visible to others, yet I can discern it's red compared to the surrounding skin. The only recent change in my daily routine has been the introduction of some new lip products, so I'm contemplating stopping their use to determine if it could be an allergic reaction. My partner suspects it might be herpes or even cancer, which has certainly heightened my concern. Additionally, I recently applied a face mask that caused significant irritation to the affected area, which has me increasingly anxious about what might be happening. I admit I’m feeling quite anxious and would appreciate any insights, as I have been preoccupied with fears about the possibility of oral cancer or a sexually transmitted infection. I’ll attempt to share some images in the comments, but please note that my camera quality isn’t great. Lastly, I want to mention that I completed a course of antibiotics about a week ago for an ear infection, and I haven’t noticed any changes in the condition of my lip since then, which may or may not be relevant.
