Concerns About Fingernail Changes
Hello, I’m a 34-year-old man, turning 35 in November. Standing at 5 feet 7 inches tall and weighing around 210 pounds, I used to smoke but kicked the habit over three years ago. I have ulcerative colitis, and while I may not be in peak health, I maintain an active lifestyle. I wanted to reach out regarding an issue with my fingernail. Not long ago, I noticed some additional skin developing underneath the nail. Initially, I presumed I had simply trimmed it incorrectly. It didn’t cause any issues for quite some time, but more recently, I’ve observed the emergence of dark lines on the surface of my nail, which has raised my concerns. Does anyone have insights or suggestions about this situation?

It's understandable to be concerned about changes in your fingernails, especially when you notice something unusual like skin growth or dark lines. Fingernail changes can arise from various factors, including trauma, infections, or underlying health conditions. Given your history of ulcerative colitis, it's prudent to monitor any new developments closely.
Explanation
The appearance of dark lines on your fingernail could be due to several reasons:
-
Trauma or Injury: If you accidentally injured your nail while trimming it, that might explain the skin developing underneath and any subsequent changes to the nail's appearance.
-
Nail Psoriasis: Having a history of ulcerative colitis increases the risk of developing conditions like psoriasis, which can affect nails.
-
Melanonychia: This term refers to dark streaks or lines on the nails, which can be caused by a range of issues, including benign causes or more serious conditions.
-
Nutritional Deficiencies: Conditions like colitis can affect nutrient absorption, leading to nail changes.
Next Steps
-
Monitor Changes: Keep an eye on the nail and any associated symptoms, such as pain, swelling, or changes in surrounding skin.
-
Track Additional Symptoms: Note if you experience any other signs like nail thickening, separation from the nail bed, or changes in other nails.
-
Practice Good Nail Care: Keep your nails trimmed and clean, and avoid trauma to the area. Moisturizing the nail bed may help as well.
-
Consider Nutritional Support: Ensure your diet is rich in essential vitamins and minerals, such as vitamins A, C, D, and B12, as well as zinc and biotin. Discuss your diet with a nutritionist if needed.
-
Photo Documentation: Take photos of the changes over time; this can help you track their progression and is useful if you consult a professional later.
If the dark lines worsen, or if you develop additional symptoms like changes in color of the nearby skin or pain, it would be best to seek professional evaluation to rule out any serious conditions. Remember, you know your body best, so trust your instincts about when to seek further help.

20-Year-Old Struggling with Ongoing Symptoms During Physical Activity
For nearly five months now, I have been experiencing persistent and vague discomfort. Adding to my challenges is my long-standing battle with severe anxiety, which often leads to sporadic symptoms. However, what truly alarms me is the feeling of unease I face every time I engage in physical activity or movement. Each time I rise to my feet or take a stroll, I find myself grappling with bouts of lightheadedness or dizziness. More often than not, it feels as if my body lacks strength and is unusually weak, rather than the sensation of imminent fainting. It’s worth mentioning that I have only experienced genuine presyncope—characterized by darkening vision and muffled sounds—following blood draws and once during gym class as a child when exposed to heat. In addition to this, I frequently encounter other unusual symptoms. Occasionally, these are connected to my chest, manifesting as mild tightness predominantly on the left side, a feeling of fullness, or even a slight ache. At other times, I experience an array of random sensations, including pressure in my head or ears, a sense that my vision isn’t quite right (though I haven't lost clarity or experienced blurriness; perhaps dissociation is a factor), or a feeling akin to shortness of breath—not gasping for air, but rather an odd tightness or discomfort in my airways. Naturally, I’ve considered the possibility of postural orthostatic tachycardia syndrome (POTS), especially as my heart rate can be quite reactive, sometimes spiking over 40 beats per minute just from the simple act of standing. Yet, there are days when my heart rate doesn’t respond as dramatically. My symptoms tend to fluctuate day to day; even within the same day, I often find greater relief in the evening. I'm acutely aware that my physical conditioning is lacking. Even prior to my symptoms worsening and my anxiety being partially managed, I was not particularly active. A couple of weeks ago, I attempted a 10-minute workout designed for seniors, and I found myself extremely sore afterward, with my heart rate soaring to 190 beats per minute. Nowadays, my exercise consists of pushing myself to walk around my house or yard for short intervals, practicing gentle yoga, preparing meals, and attending to my personal hygiene. As someone recovering from agoraphobia, I’m primarily confined to my home, venturing out only for planned exposures. With a move looming less than a week away, I’m consumed by anxiety over how this might impact my health, fearing it could lead to a hospital visit. Recently, I’ve been dedicating around 30 minutes each night to packing, which has been challenging, yet I managed to continue. However, when I tried to pack earlier in the day, I became so fatigued that I had to cease my efforts after only 40 minutes. This exhaustion has recurred, and just recently I felt fleeting tight or stabbing chest pains while packing in addition to the usual discomfort. Yesterday and today, I also experienced general chest tightness and periodic dull pain on my left side, which is distressing every time it occurs. Additionally, I'm plagued by feelings of air hunger and dyspnea. Increasingly, I find myself conscious of how routine activities feel perilous due to these alarming symptoms. Just today, I noticed these sensations while taking out the trash and even while playing the piano. I’m in the midst of finding a new primary care physician since my previous doctor closed their practice, but my first appointment is still weeks away. Back in March, I had a telehealth visit and blood tests, which yielded little clarity—only revealing some minor, potentially insignificant abnormalities. Although I’ve worried about possible heart-related issues, I had an EKG and a Holter monitor just two years ago that returned normal results. Still, I feel that’s not sufficient reassurance, and I plan to request a referral for a cardiologist when I finally meet with my new doctor.
Eliminating Warts: A Personal Experience
For approximately a year, I dealt with a wart, but when my sister inadvertently pulled it off, another one appeared, resulting in two warts now. Currently, I'm on vacation in Turkey, where I picked up a product designed to help with wart removal, referred to as "DUODERM (%16.7) deri çözeltisi," which roughly translates to "Skin remover" or "dissolve skin." I’m curious about the proper application method. So far, I’ve been placing it directly on the warts, allowing it to sit untouched for five days. Should I be taking any additional steps?
Unexplained Symptoms and Blood Test Results
I’ve been experiencing symptoms associated with Postural Orthostatic Tachycardia Syndrome (POTS). Initially, my vitamin B12 level registered at 200, while my vitamin D was critically low at 7.5 ng/ml. After some time, I managed to boost my B12 to 700 through supplementation and brought my vitamin D up to 89. The onset of these symptoms occurred in January 2025. Since then, I have seen an improvement with several symptoms disappearing, including a burning sensation throughout my body, which subsided after just three days of B12 intake. Additionally, I had experienced significant weight loss (8 kg), followed by a recovery in my appetite, gastrointestinal distress, pain in the upper right side of my abdomen, petechiae, pale skin, and episodes of early morning insomnia. However, I continue to battle several ongoing issues, such as POTS-related symptoms, extreme brain fog, dizziness, a feeling of lightheadedness, tingling sensations, tremors, pressure in the head, non-restorative sleep, and frequent headaches. The only noteworthy laboratory finding has been a low white blood cell count, which has fluctuated between 3100 and 4500 over the past few days. What could be the underlying cause of my symptoms?
Concerns Regarding My Toenail
Greetings. Here’s my situation: I'm an 18-year-old male who doesn’t take any medications aside from some vitamins and fish oil. Approximately six months back, I began noticing an unusual change in the center of my toenail. It resembled the effect moisture creates under loose skin, if that analogy resonates. A few weeks later, following a shower, part of the nail began to peel away. I didn’t forcibly remove it, but over time, the entire nail from where the issue began to the tip completely detached. I initially assumed that was the end of it. However, a month or two ago, I observed a dark red stripe emerging in the spot where the issue previously manifested, which appeared to resemble blood. There was no discomfort when I pressed on it, and I wouldn't have even detected it by touch; it was only visible to me. Due to the absence of pain, I haven’t given it much thought until recently when my toenail began to peel again. I’m perplexed and am seeking guidance to resolve this issue. I suspect that my rock climbing shoes, which are designed to fit snugly, might be to blame, but interestingly, they do not cause me any discomfort on my toes, and I can't recall any incident where I might have stubbed my foot.
Returning to Weightlifting After Ciprofloxacin Treatment
I'm a 28-year-old man who enjoys weightlifting, and I recently began a course of Ciprofloxacin for a severe infection that landed me in the hospital. Although my doctor seemed relaxed about my condition, doing some research on the medication left me quite alarmed by the potential side effects. Weightlifting is a significant part of my life, and the uncertainty regarding when I can return to the gym is taking a toll on me mentally. I’m currently on the fourth day of my treatment, and I can’t wait to get back to my regular workout routine. Thankfully, the infection appears to be clearing up. I would appreciate any insights or advice from others who might have experienced a similar situation. Thank you very much in advance!
