Persistent Pigmentation Issue on My Buttocks
I’m a 34-year-old female, and approximately three months ago, I discovered a peculiar patch on my buttocks, specifically in the area that makes contact with surfaces when I sit. This area felt unusually dry, raised, and irritated. Initially, I sought guidance from my local pharmacy. Given that the patch is located where my sanitary pad sits at night, the pharmacist speculated it might be a fungal infection and recommended Clotrimazole cream. However, after three weeks of application, I found no improvement. Consequently, I consulted with a doctor, who diagnosed me with contact dermatitis. Following this, I underwent several treatment cycles with Fucibet ointment, taking a break of one week for every two weeks of usage, a regimen I maintained for about six weeks. Now, the patch has leveled out and resembles standard skin texture, though there's still noticeable hyperpigmentation. During my appointment today, the doctor mentioned that the exact cause remains unclear. They decided to conduct blood tests and are considering a biopsy with a dermatologist once my referral is processed. Has anyone experienced something similar or have any insights?

It sounds like you've been dealing with a challenging and frustrating skin issue, and I can understand your concerns about the persistent pigmentation and the uncertainty surrounding the diagnosis. Here’s a summary of your experience and some actionable steps you can consider moving forward.
Main Points:
- You are experiencing a persistent patch on your buttocks that was initially diagnosed as contact dermatitis.
- Treatments so far, including Clotrimazole and Fucibet ointment, have helped, but the hyperpigmentation remains.
- A referral for further evaluation with a dermatologist is in progress.
Explanation:
Contact dermatitis can occur due to various irritants or allergens, particularly in areas that are often in contact with materials like sanitary pads. Even though the raised and dry nature of the patch has improved, hyperpigmentation (darkening of the skin) can take longer to resolve after the initial irritation has diminished. It's important to have ongoing evaluations, as your current doctor has recommended, to rule out other possible conditions.
Next Steps:
- Continue monitoring the patch: Keep track of any changes in size, color, or texture. Take pictures weekly to help document its progress.
- Avoid irritants: Since you suspect contact dermatitis, try to minimize friction and moisture in the area. Consider using breathable cotton underwear and ensuring that your sanitary pads are suitable for sensitive skin.
- Topical treatments for pigmentation: While you wait for the dermatology appointment, you can start using a gentle hydrating moisturizer in the area. Products containing ingredients like vitamin C or licorice extract can also help brighten hyperpigmented areas, but avoid anything too harsh or irritating.
- Follow up on blood tests and biopsy: Ensure to discuss any additional symptoms with your doctor, and be prompt in scheduling any follow-up appointments in case the biopsy is recommended.
By taking these steps, you can help manage your condition and support your skin while you await further evaluation from a specialist. Feel free to reach out if you have more questions or need further support!

Essential Screening Measures Following Nipple Discharge in a Young Woman
A 20-year-old female (my daughter) stands at 5 feet 5 inches tall and weighs 118 pounds, maintaining a physically active lifestyle. Recent development: Approaches for cancer screening after her experience with nipple discharge in a 20-year-old female. She observed a blood drop from her nipple, specifically from the area where a small hole exists. Uncertain if it originated from inside the breast or if it was simply a scratch, she expressed concern. Her skin has been notably dry and itchy, leading to an upcoming dermatologist visit to address her skin condition. Furthermore, she mentioned that one of her breasts felt different. Having breastfed my children, I recognize that variations in the milk duct can cause changes in breast sensation, such as a potential tumor. Upon her own initiative, she arranged a visit to her pediatrician. As expected, the physician conducted a manual breast examination, concluding that the examination revealed no irregularities. The pediatrician speculated that the bleeding likely stemmed from her dry, itchy skin and prescribed a topical cream. I had not attended this appointment; my daughter managed everything on her own, and I learned about it because my contact information was linked to the office for appointment confirmations (which I plan to rectify). She appears somewhat reticent about discussing this issue. To assist her, I purchased a pack of pregnancy tests to rule out that possibility now and again after a couple of weeks, since she does not experience menstruation due to her contraceptive medication. The initial pregnancy test returned a negative result. In my view, it would be prudent for her to undergo some form of cancer screening, possibly an ultrasound, mammogram, MRI, or another suitable procedure. However, I am uncertain about the most appropriate initial step in this situation. I would prefer to avoid a mammogram if a less invasive option is available, while ensuring thorough screening. Fortunately, we live in an area with numerous walk-in health clinics, allowing us to seek referrals for an ultrasound, MRI, mammogram, etc. I would appreciate guidance on what would be the best procedure to request. I do not wish to question the pediatrician’s expertise, yet I recognize that breast cancer is a specialized area and not commonly encountered in young patients. Considering my daughter's report of changes in her breast sensations, I find it difficult to reconcile this with the pediatrician's assessment. There is no family history of breast cancer in my family; however, my paternal cousin has a family history unrelated to my direct lineage. A related concern: My daughter has scheduled vacations in the next two weeks. If this timeline is too lengthy to wait for possible screenings, I will make arrangements for her to be screened wherever she is or accompany her back home for a day of testing. Conversely, if two weeks are considered an adequate timeframe, please inform me of that as well. Thank you. Current Medications: - Lo Loestrin Fe 1-10 - Dextroamphetamine 15 mg - Bupropion HCl XL 150 mg - Gabapentin 300 mg (though I believe she takes this infrequently and it may have been substituted with Trazodone) - Trazodone 50 mg Topical Treatments: - Tretinoin 0.025% Cream - Dapsone 7.5% Gel - Triamcinolone 0.1% Cream I appreciate your assistance in this matter.
Understanding Preiser’s Disease
Approximately a year and a half ago, I received a diagnosis of Preiser’s disease affecting my dominant hand. After undergoing surgery to address a microfracture, I found no relief from my ongoing symptoms. The physician informed me that other surgical interventions carry significant risks, yet unfortunately, my condition continues to deteriorate. Additionally, I've begun experiencing sensitivity in the corresponding bone of my non-dominant hand, despite an MRI revealing no irregularities in that area. I’m a 29-year-old female who maintains an active lifestyle, stands at 1.70 meters tall, and has a BMI of 24.5. I do not smoke.
Three Years of Sinus Distress: A Call for Assistance
I am a 36-year-old woman with a history of cancer, having undergone chemotherapy, radiation, and immunotherapy (Keytruda), which I stopped around 2021. Approximately a year later, I began to experience troubling symptoms after spending some time in Egypt, where I encountered polluted air, smoke, and engaged in occasional smoking myself. My main concerns include: - Constant nasal swelling and a sensation of tightness as if the tissue inside my nose is "stuck together." - Development of thick crusting within my nasal passages that sometimes obstructs airflow by sealing the tissue shut. - Although my ENT examinations reveal no active infections, doctors consistently note that my nasal tissue appears "inflamed." - Additionally, I endure swelling and discomfort in the lymph nodes throughout my body. - While a few antibiotics have offered temporary relief, the symptoms return once the medication is stopped. I noticed improvements when taking Bactrim, cefadroxil, and doxycycline, but Cipro did not provide any benefits. This ongoing sinus issue has plagued me for around three years, with sensations of rawness and extreme crusting reported—one ENT even rated my condition as 9 out of 10 for crusting severity. After living in Egypt for over a year dealing with this discomfort, I returned home in hopes of better healthcare support. Throughout this period, I've undergone MRIs and CT scans, visited three different ENTs, and even had a surgical procedure intended to remove the crusting. Despite the procedure, my symptoms recurred. Recently, another ENT agreed to culture my sinuses for the first time, despite my ongoing antibiotic treatment during the swab. The result was a "scant" presence of Serratia, with sensitivity testing indicating that while Cipro could potentially work, it was among the least effective treatments I have tried. Based on the sensitivity results, I switched from cefadroxil to Bactrim, which unfortunately coincided with a resurgence of pain in my lymph nodes. My doctor advised me to rely solely on Bactrim, but I find this troubling. The situation is overwhelmingly distressing. The discomfort is localized to my left sinus and seems to radiate into my ear, enveloping much of my head—a complication rooted from a previous fungal infection in my ear. I am currently under the care of an infectious disease specialist who has conducted over 20 tests, especially considering my history of travel and potential autoimmune disorders. I have expressed my concern that the lymph node issues are linked to my nasal condition, yet he appears skeptical. When I first returned to the States, I was suffering from open sores within my nose, which improved significantly with the application of mupirocin. Today, my ENT prescribed a nasal rinse containing xylitol, mupirocin, and gentamicin, which provides some relief, although it feels like a minor effort against a larger problem. I am feeling incredibly desperate at this stage. There is an unsettling thought of returning to Egypt, as I might have easier access to necessary testing and treatments. I spent three years largely confined to bed due to cancer, and now this sinus issue has me nearly bedridden again. Any guidance or assistance would be immensely appreciated.
Concerned About Unidentified Tissue During Bowel Movement
I’m a 20-year-old female with a BMI of 21. Although I have an eating disorder, I’m not sure if it directly relates to my current issue, but I believe it’s important to mention for context. I have used laxatives occasionally, although significantly less than in the past. I understand the dangers associated with them and have experienced withdrawal symptoms, including constipation, so I’m aware of the potential consequences. In 2023, I would typically take around 10 laxatives nightly for months, occasionally increasing to 20, but I ceased this habit in late 2024. Since then, I have relapsed and now only take them two to three times each month over the last six months. On Wednesday night, I consumed 16 laxatives and completely evacuated my bowels. Subsequently, on Thursday night, I took 4 more to clear the remnants of my meal from Wednesday. Today, however, my stools have been completely liquid and devoid of solid matter for the past two or three bowel movements, until just now. When I wiped, I discovered something unusual. I initially searched online to identify what it could be, thinking perhaps it might be a pill casing from a probiotic I had taken earlier; however, the texture does not resemble that at all. It feels like some kind of tissue, similar to the consistency of period blood clots—stringy, fibrous, rubbery, and surprisingly tough. This has raised an additional concern: I’m uncertain whether this substance exited from my anus or vagina, as it was positioned near the exterior of the anal area. Today, I’ve experienced significant abdominal cramps, which is puzzling since having a hormonal IUD has usually alleviated my menstrual symptoms. I haven’t consumed any food today except for a spicy salad with peppers, cucumber, tuna, and dressing, and nothing from that meal has come out, so I doubt it could be food-related. In my concern, I flushed the tissue, thinking that by the time I would be able to see a doctor, it’d be too late for examination. Now I’m regretting that decision and questioning whether I should have stored it in some way. Additionally, I’m unsure if it’s reasonable to make an appointment with my GP over this, so any guidance on how to proceed would be greatly appreciated. I’m feeling anxious because I can’t seem to reconcile this incident with any normal explanation. If anyone has any insight, I’d be immensely grateful. EDIT: I’ve been contemplating the possibility of this tissue originating from my vagina instead of my anus, as that makes more sense to me. Could this be indicative of a fibroid? While spontaneous discharge appears to be uncommon according to medical sources, the descriptions and some images I’ve seen seem somewhat similar.
Testicular Pain and Bump: What’s Going On?
Summary: I’m a 16-year-old male, and I’ve been experiencing discomfort in my right testicle when it’s touched or pressure is applied, particularly in the upper section (possibly near the epididymis). The issue began two weeks ago after my first visit to the gym, specifically after performing leg presses. While the discomfort subsided with rest, it reoccurred briefly after swimming, and now there’s a small, hard, tender bump on the upper part of the testicle (likely where the epididymis is). There's no swelling and no history of STDs, but I did have a scrotal hernia when I was 10. Detailed Account: I’m 16 years old and have noticed pain in my right testicle whenever it’s touched, located mainly at the top (possibly the epididymis) and previously in the back. Here's a timeline of what transpired: About two weeks ago, I began my first gym session, trying out all the different machines. I might have overexerted myself with weights that were too heavy, particularly during leg presses, which I later learned could potentially lead to injury, like a hernia. Later that same day, I experienced pain in the upper and rear sections of my right testicle. I realized the pain seemed to intensify upon contact or pressure in that area. After a few days of rest, the discomfort subsided significantly, but I still felt mild tenderness if I touched the area. Approximately a week later, after going swimming, the pain returned for a short period. I also noticed that the right side of my scrotum sat slightly lower than the left, although my left testicle usually hangs lower anyway. This condition persists, but the difference is minimal. By the start of this week, the pain had nearly vanished, except for a small bump on the upper section of my testicle (what I suspect is the epididymis), which was tender to the touch. I no longer feel discomfort in the back portion of the testicle. Earlier today, the pain flared up again briefly, but it has since calmed down, only hurting when I specifically touch that area. About me: I am a 16-year-old male, generally underweight or at a normal BMI. I had a scrotal hernia at the age of 10 (before puberty) that caused swelling, but I used ice and it has been alright since. I do not have any STIs or STDs and am a virgin.
