Concern Over White Substance on My One-Month-Old Son's Genitals: Is It Typical?

9/9/2025, 1:30:36 AMMale25-34

Age of baby: 7 weeks, Gender: Male, Weight: 3.5 kg, delivered naturally at 38 weeks, initially weighed 2.62 kg. No medications have been administered. I have observed a white substance sporadically appearing on my one-month-old son’s genitals. Initially, I suspected this might be due to the disposable diapers, leading me to switch to 100% cotton fabric options. Despite this change, the white substance continues to occur. It has been noticeable for several weeks, although it does not appear every time he urinates. The substance presents as a patchy, powdery or granulated material. It manifests as small white flakes or crystalline formations on the surface of the skin, gathered in a few areas. It doesn’t resemble a smooth discharge; instead, it seems more like dried particles or crystallization. My baby shows no signs of fatigue, maintains good appetite, and remains active. I had previously discussed this issue with his pediatrician while he was still in disposable diapers, and I was informed it might be related to them. However, I haven’t had the opportunity to follow up since transitioning to fabric diapers. Upon conducting some personal research, I stumbled upon information suggesting this could be urate crystals, but I’m not entirely certain. Is this something that is typically observed in newborns, or should I be worried? I appreciate any advice you can provide!

The presence of a white, powdery substance on your one-month-old son's genitals can be concerning for parents. However, in many cases, this can be attributed to benign causes, such as urate crystals, which are the result of concentrated urine in newborns and are not uncommon. Here’s a breakdown of the situation and steps you can take.

Explanation

  1. Urate Crystals: In infants, especially those who are not well-hydrated, urates can crystallize and appear on the skin. This is typically harmless and often resolves without any intervention as the baby starts urinating more frequently and the hydration status improves.

  2. Normal Skin Variations: Babies can have a variety of normal skin characteristics, including flakes or dryness. This can be exacerbated by diaper friction or moisture retention. Cloth diapers can help, but skin care remains essential.

  3. No Other Symptoms: The fact that your baby is feeding well, is active, and shows no signs of distress is a positive sign. This indicates he is likely healthy, and the white substance is not causing him any discomfort.

Next Steps

  1. Monitor Hydration: Ensure your baby is feeding adequately. A well-hydrated baby will have more frequent urination and less concentrated urine, which may help reduce the appearance of urate crystals.

  2. Gentle Cleaning: Clean the genital area gently during diaper changes. Use warm water and cotton or a soft cloth to wipe, taking care not to irritate the skin further.

  3. Skin Care: If the skin appears dry, you can consider applying a small amount of fragrance-free moisturizer specific for infants.

  4. Document Changes: Keep a diary of the occurrences, including any changes in frequency, appearance, or if any new symptoms develop over the next week.

  5. Follow-Up with Pediatrician: Since you mentioned discussing this with your pediatrician previously, it would be advisable to follow up, especially after transitioning to cloth diapers. Discuss your observations and any changes you’ve noted.

If the white substance continues to persist, changes in appearance, or if your baby exhibits any signs of discomfort or infection (such as redness, swelling, or crying during diaper changes), seek further advice from a healthcare professional.

Please remember, while these initial steps can help, it's best to consult your pediatrician for personalized medical advice, especially if you have concerns.

I Experience Color Changes and Itching in My Legs When Standing for Too Long

I’m a 15-year-old female, and I first noticed this issue when I was around 12 or 13 years old, but it has intensified recently. Currently, I am not using any medications, and I wasn't taking anything when these symptoms started. I don’t regularly consume any drugs or alcohol. For reference, I stand approximately 5'3" tall and weigh 60 kg. The skin on my legs develops a bluish-purple hue, accompanied by distinct circular patches that are orange in color. This is not similar to ringworm in appearance. In addition to the discoloration, there's significant itching that occurs regardless of my location or attire. I suspect it's not due to environmental factors, as these symptoms manifest whether I’m at home, in school, or outdoors, unaffected by the weather or temperature conditions. Additionally, my family does not have any similar health concerns. Has anyone experienced something like this or have any ideas about what might be going on? I’ll try to share some images in the comments for better understanding.

Is This Neck Sensation Something to Worry About?

I’m a 37-year-old male and for as long as I can remember – dating back to my teenage years – I’ve been experiencing a peculiar sensation. Whenever I abruptly turn my head or stretch my neck in certain ways, I feel something akin to a rubber band being plucked between fingers, rather than the snap of it against skin; it resembles the sound of a guitar string being strummed. Following this sensation, there’s a warm, flowing feeling that spreads from the back of my neck outwards, which is soon followed by a brief episode of pain lasting around 5 to 10 seconds. This intensity subsides into a mild ache that can linger for several hours. While I don’t experience this every single time I move my neck, it’s been a recurring issue since my teenage years. **Medical History:** - In April 2014, I underwent a partial esophagectomy to excise a leiomyoma. **Current Medications:** - Carafate 1g four times daily - Nexium 40mg twice daily - Wellbutrin 450mg once daily - Lexapro 10mg once daily

Concerns Regarding Potential Pleomorphic Adenoma and Ongoing Health Issues

Greetings. I’m a 30-year-old male, recently suspected of having a pleomorphic adenoma, and presently undergoing treatment with penicillin due to a possible strep throat infection. Back in June, I discovered a notable lump developing on my jawline, which has grown quite rapidly. The medical team believes it may be a pleomorphic adenoma, and I am currently waiting for the biopsy results to either confirm the diagnosis or rule out malignancy. Alongside this, I have been suffering from symptoms such as a sore throat, fever, and headaches. After three weeks of these symptoms, I was prescribed Augmentin, which seemed effective at first; however, I have since experienced recurrent instances of illness, totaling three or more episodes. Since the appearance of this lump, I have been persistently feeling run down, plagued by a host of ailments such as strep throat and COVID-19, along with ongoing symptoms like sore throats, fatigue, bodily pains, headaches, and intermittent fevers. Over the summer, I underwent several blood tests to identify the cause of my poor health. Notably, my ASOT levels increased from 319 in June to 350 in September, indicating a recent strep infection. Consequently, my physician has put me on a penicillin regimen, but I have yet to notice any improvement, now on day five of the treatment. Could my ongoing health issues possibly be associated with a benign pleomorphic adenoma? If it turns out to be cancerous, perhaps that would explain my condition; but if it’s not, what could be the underlying cause? Fortunately, all my blood test results came back normal, including CRP levels, and tests for HIV and mononucleosis were also negative.

Is It Time for the ER or Can I Visit Urgent Care?

AFAB, 24, weighing 160 pounds Since last Friday, the 5th of September, 2025, I have been dealing with significant abdominal discomfort, including cramping and bloating. The following day, my symptoms escalated, leading to vomiting which forced me to take a sick day from work. Although I haven’t vomited again since then, the pain fluctuates, remaining persistent, albeit not unbearable, but uncomfortable enough to be distracting. I have struggled to have a satisfactory bowel movement; attempts have resulted in diarrhea, and I constantly feel like my bowels are not completely empty. There is a sensation of pressure when I try to relieve myself, and despite using laxatives and trying an enema, I suspect I may be experiencing some sort of blockage. Thankfully, I haven’t had a fever or experienced a decrease in appetite. I find myself at a crossroads regarding what steps to take next since I have never faced this kind of situation before and have no previous experience with hospitals or emergency rooms. I’m concerned about burdening emergency services for a non-critical issue that could potentially be treated at urgent care. Financially, I am not in a stable position and currently lack health insurance, which adds to my worries about covering any potential upfront costs for urgent care services. What should I do? Should I head straight to the emergency room, or is there a chance I could manage this at urgent care? I’m genuinely anxious about this developing into something more severe and all I want is to feel normal again.

Seeking Advice on Managing a Cyst

I have been diagnosed with a 3.5 cm fluid-filled cyst on my left ovary. Initially, I consulted a physician who prescribed Primolut for three weeks, with instructions to repeat the course afterwards. However, after completing the initial treatment, the symptoms intensified to the point where I found it unbearable to continue the medication. Subsequently, I endured a month-long wait until my menstrual cycle resumed. During this period, I sought a second opinion from another doctor, who informed me that the cyst had reduced to 1.8 cm. She advised me to return for a follow-up in a few weeks. However, when I eventually returned two months later, the cyst had expanded back to 3.5 cm. The doctor presented me with two choices: to undergo a six-month course of medication (which she didn't specify but indicated it would prevent pregnancy) or to consider surgical removal. I'm reaching out for honest and trustworthy advice, as I've encountered some medical professionals who seem more concerned with financial gain than patient care. I have a strong aversion to medication and prefer not to disrupt my hormonal balance or my overall health. Any guidance would be appreciated.
