Concerns About Toenail Discoloration
Hello, a month ago I discovered a discolored spot on my big toenail. Initially, it was quite faint, and the nail itself wasn't lifting significantly at that point. Since I hadn't experienced any trauma, I presumed it was a subungual hematoma, possibly caused by my footwear. To minimize any pressure on it, I've opted to wear crocs exclusively over the past weeks instead of my regular shoes. The bruise was not painful, so I didn’t seek medical advice, believing it would resolve itself eventually. Up until recently, there have been no issues with the bruise—no pain or discomfort. However, I did experience some tenderness about a week ago before I truly noticed the bruise beginning to form. Just three days back, nearly four weeks after the initial sighting of the bruise on my larger toenail, I observed what appeared to be spreading discoloration to the smaller toenail adjacent to it. Initially, the smaller toenail looked normal, but I detected a subtle sensation of bruising. Today, although I didn't examine my toe yesterday, I noticed that slight discoloration becoming visible; however, the bruised sensation has faded. This mirrors what happened with my big toe, where the discomfort ceased as the bruise became apparent. I have not experienced any impact to either toenail, and I've been cautious to prevent any pressure, which leaves me puzzled as to why another bruise seems to be developing. I'm worried that both nails might eventually detach. I'm beginning to question whether it was even a bruise in the first place. Any thoughts on what this might be? (18 years old, no prior diagnoses, and currently not on any medication.)

It’s understandable to be concerned about changes in your toenails, especially when you’re noticing discoloration and potential spreading. Based on your description, the initial spot may not just be a simple bruise and could potentially point to other underlying issues, such as a fungal infection or a condition affecting your nails.
Explanation
Toenail discoloration can arise from various causes, including:
-
Subungual Hematoma: This typically occurs due to trauma, causing blood to accumulate under the nail. Since you mentioned no prior trauma, this might not be the cause.
-
Fungal Infection: Discoloration can also indicate a fungal infection, which may start in one nail and spread to others, contributing to changes and tenderness.
-
Other Conditions: Certain skin conditions or systemic issues (e.g., psoriasis, nail matrix issues) can affect nail appearance, sometimes mimicking bruising.
Given that there’s tenderness, spreading discoloration, and the initial area of concern has transitioned, it's important to carefully monitor these symptoms as they can sometimes progress.
Next Steps
-
Continue Monitoring: Keep a close eye on any changes in discoloration, tenderness, or the overall condition of your toenails. Monitor how they look and feel a couple of times a week.
-
Maintain Good Foot Hygiene: Wash your feet regularly and keep your toenails trimmed and dry. Wearing breathable footwear can reduce moisture buildup that promotes fungal growth.
-
Avoid Tight Footwear: While crocs are a good choice to minimize pressure, ensure they have arch support to prevent discomfort.
-
Consider Antifungal Treatments: If you suspect a fungal infection, over-the-counter antifungal nail treatments may be beneficial. Apply them as directed.
-
Seek Professional Advice: If the discoloration continues to spread, you notice any changes in pain levels, or if the nails become detached, it’s crucial to seek medical advice from a healthcare professional or dermatologist. They can properly assess your condition and provide an accurate diagnosis.
Remember, it’s always better to err on the side of caution with changes in your health. You’re taking the right steps by being proactive about your concern. Let me know if you have more questions or need clarification!

Seeking Answers for My Brother's Ongoing Health Struggles: Age 31
My brother has been experiencing persistent inflammation, particularly affecting his ankles and knees. For more than a year and a half, he has faced significant mobility challenges, making it impossible for him to walk without assistance. Despite numerous consultations with various doctors who have conducted extensive testing, we have yet to uncover any definitive explanation or solution for his condition. Instead, he has been shuffled from laboratory to laboratory for over a year, leaving us in the dark about his health issues. In my quest to help him, I recently obtained his medical test results, and I'm eager to decipher them, especially given my concerns that his condition may deteriorate further. Here are the highlighted abnormal findings from his tests: - WBC: 14.6 (Elevated) - Hemoglobin: 12.8 (Decreased) - Platelets: 501 (Elevated) - Neutrophils (Absolute): 11.5 (Elevated) - Creatinine: 1.29 (Elevated) - BUN/Creatinine Ratio: 5 (Decreased) - Albumin: 3.8 (Decreased) - A/G Ratio: 1.1 (Decreased) - HDL Cholesterol: 36 (Decreased) - LDL Cholesterol: 125 (Elevated) - Hemoglobin A1c: 6.1 (Elevated) - TSH: 0.27 (Decreased) - Urinalysis: Appearance Cloudy (Abnormal) - Urinalysis: Protein 1+ (Abnormal) - Urinalysis: RBC 11–30 /hpf (Abnormal) I hope to find some clarity regarding these results and seek a pathway to improve his situation.
Persistent Bump on the Arm: Concerns?
Greetings everyone, I find myself uncertain about how to describe this situation. I have developed a bump on my arm that resembles swelling but lacks any visible bruising. It appears to be located near my bone on the left forearm. Initially, it didn’t cause me any discomfort; I assumed I might have bumped it against something, and it disappeared within two weeks. However, about a month later, it resurfaced, fading away once again after two weeks. As you might expect, it vanished again, but today it has reappeared and feels particularly painful. Should I be concerned about this issue? For context, I’m a 16-year-old male with no significant health concerns, I'm not on any medications, and I do not engage in smoking or drug use.
Irritation on Scrotum from Shampoo
I inadvertently applied Head and Shoulders shampoo to my scrotum and have been suffering sharp pain for several hours. It seems likely that the discomfort is due to a chemical burn caused by the product. Are there any remedies I can use to alleviate the pain? I’ve been trying to soothe it with Vaseline and ice packs. I am a 44-year-old male. Thank you for any suggestions!
Discharge from Belly Button: What Should I Do?
I'm a 27-year-old female with a history of endometriosis, asthma, and anxiety, and I take duloxetine along with avoiding alcohol and smoking. Occasionally, I like to use a small camera to check my unusually deep belly button for lint or other debris. Just recently, while inspecting it, I discovered a pus-filled sac. Out of curiosity, I squeezed it, and I must admit I felt quite nauseated by the experience (I might include a clip of it; it’s truly unpleasant). For as long as I can remember, there's always been a small fleshy bump at the center of my belly button. When I was around ten years old, I had an incident where it expelled pus or some liquid for about a week, and it was both gross and embarrassing. However, I noticed that the bump shrank after that occurrence. Earlier, I managed to extract a fair amount of the pus. Unfortunately, my camera has since run out of battery, so I'm unable to re-investigate. Given this situation, I'm wondering about the implications of this episode. Should I seek an in-person consultation with a healthcare provider? My annual check-up is scheduled for October—can this wait until then? I appreciate any advice!
Unexpected Chills
I’m a 32-year-old male, measuring 6 feet 3 inches tall and currently weighing 255 pounds as I strive to lose some weight. I’m not on any medications, consume maybe one alcoholic beverage per month, and don’t use drugs. I maintain a gym routine four days a week and enjoy hiking two miles on both Saturday and Sunday. I want to discuss those involuntary body chills one might experience in frigid conditions or when battling the flu. These chills can be severe enough that my body quakes uncontrollably — it’s rare that I can suppress this reaction. I also experience symptoms like chattering teeth. Interestingly, these chills can arise from unusual triggers: - A couple of weeks ago, I accidentally bumped my knee. There was no bruise, but the impact felt similar to hitting your funny bone. About an hour later, I was struck by intense chills. - Just an hour ago, I lightly scraped my foot, with no visible wounds, bleeding, or bruising. Yet, I’m now left feeling fatigued with those familiar chills creeping in. This phenomenon has been a part of my life since childhood. A friend of mine recently mentioned that this experience isn’t typical. Is there anyone else who encounters similar issues?
