Long-Lasting Dark Spot on Heel: What's the Cause?
For the past three weeks, I’ve noticed a dark spot on my heel that I initially believed to be a blood blister. However, it doesn't appear to be improving. I've recently started wearing new footwear, which led me to think the new shoes might be related to the issue. Could this possibly be an infection, or is it indeed a blister? When I apply pressure, the area feels firm, but there's no pain associated with it. Location: Right heel. Age: 28, Male.

The persistent dark spot on your heel could be due to several factors, including pressure from new footwear, a bruise, or even a form of skin discoloration. Given that it has been present for three weeks and feels firm without pain, it is less likely to be an infection or a typical blood blister, which would usually be tender or painful.
Explanation
When new shoes are worn, they can cause friction or pressure that may lead to discoloration of the skin, especially if they're too tight or not well-fitted. If the spot feels firm and there’s no additional swelling, warmth, or pain, it might just be localized skin irritation or a bruise. However, there are other possibilities, such as:
- Bacterial or fungal infection: These usually have accompanying symptoms, so lack of pain or other signs makes this less likely.
- Hyperpigmentation: Sometimes skin changes color due to pressure or trauma.
Next Steps
-
Monitor the Spot: Keep an eye on its changes over the next week. Look for any signs of increased redness, swelling, or pain. If any of these develop, it may require further attention.
-
Footwear Review: Consider the fit of your new shoes. Ensure they are comfortable and provide adequate support. If they seem to be causing friction, switch to different footwear temporarily.
-
Gentle Care: Maintain hygiene by washing the area with mild soap and water. Apply a moisturizing lotion to help keep the skin healthy and reduce irritation.
-
Limit Pressure: Try to rest your feet as much as possible to avoid further irritation. You might consider using cushioned insoles to reduce pressure on the heel while wearing shoes.
-
Consider a Protective Barrier: If you need to wear potentially irritating footwear, you might try using a padded bandage over the area to protect it.
If the spot does not improve within a week, changes significantly, or becomes painful, further evaluation could be helpful to rule out other causes. Please take care of your feet!

Severe Anal Pain for the Past Five Days
Greetings. I apologize if my English isn't perfect, as it's not my primary language. Five days ago, I began experiencing intense pain in my anal area after bowel movements. The discomfort has escalated to the point where I find it nearly impossible to sit, lie down, or even stand. I have been in tears throughout the day due to the unbearable nature of the pain. Sleep eludes me at night. Initially, I suspected hemorrhoids, as my symptoms resembled those I experienced in the past when I dealt with them several times. However, despite using medication, the pain persisted. After two days of suffering, I went to the emergency room, where I conveyed the severity of my discomfort. The doctor conducted a physical examination and stated that she couldn't identify anything unusual. She advised me to see a surgeon on the following Monday since Friday was a holiday in my country. Unable to endure the pain until Monday, I sought help at another hospital. After a physical examination and blood tests, the second doctor also mentioned that he could not detect any abnormalities and presumed it to be hemorrhoids. I was prescribed a cream for hemorrhoids, amoxicillin, and additional medication. However, unlike typical hemorrhoids, I noticed a firm, ball-shaped growth in my anal area that matches my skin tone rather than the usual purple hue associated with hemorrhoids. This mass causes pain whenever it is forced inward, probably due to muscle tension. Conversely, when it protrudes during bowel movements, it doesn’t hurt, but I find it impossible to remove in any other circumstances. I experienced a rupture yesterday, which resulted in a small amount of blood after defecation. What could be the cause of this condition? I am extremely frustrated and anxious about my upcoming appointment tomorrow, fearing that the doctor will once again diagnose it as hemorrhoids.

Is There Such a Thing as Too Much Flavored Water?
As a 17-year-old female, I’ve begun to think that I might be facing a cavity issue. The primary shift in my dietary habits over the past six months—apart from a general decrease in food intake—has been an increased consumption of flavored water. Typically, I go through one to two bottles daily, each containing about 32 ounces. I recently stumbled upon some information online suggesting that excessive flavored water could be a factor in promoting tooth decay. Although I exclusively use sugar-free flavoring and maintain a twice-daily toothbrushing routine, I must confess that my consistency in dental hygiene only started a few years ago. A dentist visit is scheduled in two weeks to look into this matter, but I can’t shake off my curiosity and mounting anxiety. It’s particularly unsettling since the potential cavity is on one of my front teeth, making it noticeable when I smile, which adds to my embarrassment.
Concerns about a Soft Lump in the Lower Abdomen
Greetings, I'm a 39-year-old male, standing at 194 cm (6'3") and weighing 87 kg, and I hail from the Netherlands. I engage in drinking and smoke cigarettes. Earlier today, I discovered a soft lump on the right side of my lower abdomen. It measures approximately one inch in diameter and protrudes about half an inch from the surface of my skin. Notably, it does not cause any pain. I can push it back into my abdomen without any discomfort, though it reappears after a second. When I attempt to press it back in, I detect a slight resistance at a certain point, as if it encounters something. Naturally, this situation has raised my anxiety. To add to my concern, I have a holiday planned starting tomorrow, and I am uncertain about the level of urgency of this issue. I appreciate any insights or advice you may have regarding this matter. Thank you!
Is It Unsafe to Wake Up with a Numb Arm from Sleeping on the Opposite Side?
As a 30-year-old woman weighing 140 lbs and standing at 5 feet 3 inches, who also vapes, I find myself facing a peculiar situation every time I sleep. When I settle down on my side, the arm that rests on the opposite side becomes entirely numb. Just a short while ago, I woke up feeling alarmed, convinced that my arm had been paralyzed; there was absolutely no sensation at all! It felt as if my arm was just limply hanging by my side, requiring me to grasp it with my other hand to regain any awareness of its existence. This sensation was reminiscent of the time I received an epidural during my pregnancy; when my legs went numb, it was as if they'd turned into rubber, feeling unreal when I touched them. In the end, after a couple of minutes of simply letting my arm hang, normal sensation began to return. This isn't an isolated incident—the opposite arm has been prone to numbness nearly every night, although it usually only experiences a mild static-like sensation. However, the intensity of today's experience has triggered concern about potential issues concerning my cardiovascular health or blood circulation. I’m reaching out to see if anyone else has encountered similar experiences or if anyone can share insights on whether this could indicate a more serious underlying problem.
