A Unique Shade of Perspiration
For as long as I can recall, I have experienced a peculiar phenomenon—my sweat is blue. This unusual trait has resulted in my t-shirts developing noticeable blue stains in the underarm area. Despite this oddity, I maintain a robust level of health at the age of 30. Thankfully, it doesn’t lead to any other complications, aside from the simple need to frequently purchase blue shirts.

It's intriguing that you've observed blue perspiration without experiencing any other health issues. This condition is often attributed to the presence of a pigment known as "copper." This pigment can be secreted in sweat due to genetics or even certain dietary factors, but its exact cause can vary among individuals. Here's a breakdown of what you might consider:
Understanding Your Condition
- Genetics: Certain genetic traits can lead to the production of colored sweat due to variations in sweat composition.
- Diet: Foods high in certain pigments (like beets or food dyes) and supplements containing copper could contribute to this phenomenon.
- Medications: Some medications can cause changes in sweat compounds, leading to unusual colors.
- Hygiene Products: Dyes in lotions, deodorants, or detergents might combine with sweat and create stains.
Prioritized Next Steps
-
Monitor Your Diet: Reflect on any recent dietary changes or supplements that may correlate with the onset of blue perspiration. If you've added any new foods or products, consider eliminating them for a period to see if there's any change.
-
Track Symptoms: Keep a record of when the blue staining occurs, such as when stressed, active, or after specific meals. This information can help identify patterns.
-
Test Products: If you use any new lotions or hygiene products, consider switching to unscented or dye-free options to see if this affects the color of your sweat.
-
Consult Resources: While you've not experienced health complications, if it continues to concern you, consider educational resources or forums for others with similar experiences. Engaging with a community may provide insights and comfort.
-
Laundry Solutions: To manage the blue staining on shirts, consider using stain removers designed for colored stains or washing clothing in cold water to prevent setting the stain.
It's perfectly normal to have concerns about your body, and knowing that you're healthy overall is reassuring. If you have any other specific questions or if new symptoms arise, don't hesitate to ask.

Urgent Assistance Needed: Experiencing Partial Paralysis in My Fingers as a Keyboard Musician
Age: 56 Gender: Female Height: 5'4" Weight: 135 lbs Ethnicity: Caucasian Symptom Duration: Partial paralysis for three days; pain has persisted for several years. Affected Areas: Neck, arm, hand, and fingers. Relevant Medical History: Underwent rotator cuff surgery and biceps tenodesis 19 months ago. Medications: Wellbutrin 300mg, Lexapro 5mg, Jornay PM 80mg. I have battled neck problems for an extended period, experiencing discomfort when turning my head and numbness or tingling in my right hand. Approximately 19 months prior, I had surgery on my rotator cuff. Recently, after some gardening this past Tuesday, I began to notice weakness in my ring and pinky fingers on the right hand, impacting my ability to grip everyday items like a pencil or toothbrush. At this moment, I find it impossible to close my fingers properly or maneuver my pinky side to side. As a keyboardist, I am particularly distressed as my pinky just collapses against the keys, almost as if it’s immobilized. My ring finger struggles to assist as I attempt to use my pinky. After about 45 minutes of playing, I experience significant pain in my shoulder, discomfort in my upper arm, severe tingling, and relentless fatigue. At times, I am unable to press the keys at all. To make matters worse, I am currently at a performance, which feels like a complete nightmare. The prospect of needing a referral from my primary care doctor to a neurologist, waiting for months for an appointment, and being instructed to undergo physical therapy before even getting an MRI is terrifying, especially since I rely on my ability to play for my livelihood. I am genuinely worried about what might happen if these symptoms persist.
Sudden Appearance of a Flat Brown Mole
As a 20-year-old female, I've noticed a small brown mole that has emerged almost overnight on the left side of my chin, just beneath my lip. Is this something I should be worried about? I've had two black moles on my neck and calf since childhood, but this new one seems to have appeared unexpectedly on my face.
Persistent Discomfort in My Left Ear for a Year
At 17 years old, standing 5’9” tall and weighing 68 kg, I've never smoked and haven’t encountered any previous ear problems. For the past year, however, I've experienced an odd condition with my left ear. Daily, around the same time, I feel a burning sensation that escalates to the point where it seems like hot lava is flowing from it. Following this, my ear becomes red and is notably warm to the touch. I can confidently say that it's not an issue related to the skin; the area around my ear appears completely normal, except for the reddening during these episodes. While this situation isn't particularly painful, it remains uncomfortable quite frequently. I thought it would be wise to seek some insights from others about what might be causing this and whether it warrants a visit to a healthcare professional.
Deformation of Jaw Bone
(22M No medication or previous issues regarding this area) The left side of my jawbone appears to be distorted. In contrast, the right side maintains a typical "L" shape, while the left has gradually begun bending inwards over the last few years, resembling a mild staircase shape. Thankfully, I haven't felt any pain or discomfort associated with this change. However, this alteration has resulted in my left jaw being positioned higher than the right. Consequently, I've observed increasing asymmetry in my facial appearance; my head now rests at a slight angle, my right shoulder is marginally closer to my neck than the left, and there's frequent popping or cracking on the left side of my jaw. The source of this distortion seems to stem from my inconsistent use of plastic retainers after completing my braces treatment. After my sole pair broke, I only wore the left retainer. I first became aware of the jaw issue about two years ago and promptly ceased full-time retainer use. Nevertheless, the situation has only become more conspicuous, especially in recent months. My concern grows as I fear continuous jaw usage might exacerbate the bend, leading to significant complications over time. I fully intend to consult a medical professional or dentist about the matter, but that visit is likely far off since rectifying this issue appears to be neither inexpensive nor straightforward. Currently, as I can still perform daily activities without trouble, I wonder if I should be more alarmed about this condition or prioritize an earlier appointment.
Is My Nail Healthy or in Decline?
My girlfriend, who is 22 years old, underwent surgery for an ingrown toenail nearly two months ago, which involved partial nail removal from the inner side of her big toe. Since the procedure, she has been diligently soaking her foot in Epsom salts and applying antibiotic ointment two to three times each day. Initially, the healing process appeared to progress well. However, recently, she observed that the side of her nail has begun to exhibit discoloration and a depressed appearance. Is this a result of potential damage to the nail from the surgery, or could it indicate a more serious issue that might affect the nail's long-term appearance? She is concerned about the possibility of her nail falling off or becoming permanently unsightly. Additionally, it may be worth mentioning that she has a physically demanding job, and she has been on her feet a lot while recovering, which could also impact her nail’s condition.
