Unexplained Sweet Smell in My Child's Urine
My son, age 5, is an American Indian and Hispanic child who is autistic. He had comprehensive genetic testing approximately 18 months ago. He also has a history of asthma and is currently on Symbicort, along with a rescue inhaler that he uses when necessary. Recently, while tidying up his room, I detected a sweet scent emanating from his bedding. Initially, I attributed it to a possible treat he might have snuck in without my knowledge, so I merely checked for any items that could attract pests. Today, I decided to change his mattress cover and discovered some spots that appeared to be urine. Upon closer inspection, I noticed that the bedding had that same unusual sweet aroma. After giving him a shower, I checked his pull-up and was alarmed to find it also had a sweet smell, quite unlike typical urine. This situation is quite confusing for me—should I wait until Monday to contact his pediatrician, or is there an immediate action I should take regarding these concerning odors?

It’s understandable to be concerned about a sweet smell in your child's urine, as it can indicate specific health issues. The sweet odor may potentially signal conditions like diabetes or a metabolic disorder, which deserve attention.
Explanation:
The sweet smell in urine can occur due to the presence of substances like glucose, which may be elevated in cases of diabetes mellitus. While it's good to consider environmental factors, like the possibility of treats being hidden, the persistent sweet odor in your child's urine and bedding is a sign to evaluate further.
Next Steps:
-
Monitor Symptoms:
- Keep track of any other symptoms your son may have, such as increased thirst, frequent urination, unexplained weight loss, fatigue, or irritability. This information will be crucial for your pediatrician.
-
Hydration:
- Ensure he stays well-hydrated. Offer plenty of water throughout the day, as it can help dilute urine and may also help you monitor any changes in smell or color.
-
Avoiding High-Sugar Foods:
- Limit high-sugar foods and drinks until you can consult with the pediatrician, as they may contribute to changes in urine odor.
-
Prepare for Contacting His Pediatrician:
- Plan to contact the pediatrician as soon as possible. Given these symptoms, it would be better not to wait until Monday. Consider discussing your observations, including the sweet smell and any other symptoms you've noted.
Conclusion:
Your intuitive concern is valid, and taking these steps will help ensure your son’s health is closely monitored. It's always better to err on the side of caution with any unusual symptoms in children. Keep me updated on how things progress or if you have further questions.

Noticing a Soft Growth Post-Injury?
Hello everyone! I trust you are all doing well. I am a 25-year-old female and recently, I discovered a soft growth beneath the surface of my skin on my upper arm. It doesn't cause any discomfort, is mobile, and has a texture that feels either rubbery or a bit grainy. It appears to be located quite close to the skin's surface and has a mass-like shape rather than being spherical. This past fortnight, I experienced an incident with my garage door, which resulted in my arm being trapped between metal bars for approximately twenty minutes. Following that, I sustained a few scratches and developed a bruise. I’m hopeful that what I’m feeling is merely a hematoma or possibly a lipoma that has yet to fully dissipate. However, I came across information suggesting that hematomas typically present as firm, whereas this particular lump is soft to the touch. As someone who often grapples with health anxiety, I'm feeling quite anxious that it might be indicative of a more serious condition.
Lymphoma Concerns or Nutritional Issues?
At 19 years old, I tend to be a bit of a worrier about my health. Recently, I've noticed a small lymph node on one side of my neck, approximately the size of a kidney bean. It’s painless, movable, and has been there for about two months. I haven't had any infections lately, but I feel quite fatigued and often experience dizziness. Additionally, I’ve been itching at night and I woke up yesterday with a sore throat and mild chest discomfort. Importantly, I haven’t experienced any night sweats or fevers. Naturally, as someone who tends to overthink, I am concerned that this could be lymphoma. Complicating matters is the fact that I am currently in recovery from an eating disorder. I underwent comprehensive blood testing which showed normal results across the board—including complete blood count and other critical markers such as microglobulin and ferritin levels. However, it’s worth noting that I have some deficiencies in B vitamins, possibly linked to my past struggles with nutrition. Specifically, I am on the lower end of the normal range for B1, B2, and B5, while my B6 levels are notably insufficient. Fortunately, my B12 levels are within the expected range, and my levels of Vitamins A and D are also normal. So here lies my dilemma: should I invest more money into additional lymphoma testing, or could my immune system be compromised due to my past eating disorder? The initial blood tests indicate that lymphoma is less probable, which is reassuring, but they also suggest my immune system is functioning properly, leading me to question if my current symptoms can be attributed to my recovery journey.
Experiencing Disconnection During Medical Procedures
At 43 years old and undergoing cancer treatment, I’ve noticed a peculiar phenomenon: I often slip into an unusual, semi-conscious state during my sessions. Currently, this occurs mostly during my radiation therapy, but I’ve encountered similar episodes during other procedures like CT scans and MRIs, although chemotherapy hasn’t triggered it. Essentially, any time I’m positioned on a table within confined machinery seems to prompt this response. This experience isn’t something I consciously initiate, akin to meditation; rather, it occurs involuntarily. As I undergo radiation on my left breast, I employ a breath-holding method. When the technician's voice comes through the speaker instructing me to inhale, it feels akin to being roused from a profound slumber. Could this be my mind’s way of detaching from the strain of ongoing treatments? I certainly sense a high level of fatigue regarding the entire situation.
Post-Surgical Wound Concerns
Hello everyone, I’m a 32-year-old female who underwent a fusion procedure on my big toe three weeks ago, and I had my stitches removed just a week back. On Monday, I changed the bandages and the wound appeared in great condition with no sign of redness or discharge. However, during my bandage change yesterday, I noticed a significant change in the appearance of my toe. After consulting with a GP over the phone yesterday, I was prescribed antibiotics. The doctor mentioned that if there wasn’t any improvement within the next 24 hours, I should head to the emergency department to see a surgical specialist. As of now, I haven’t seen any signs of improvement. Since no medical professional has physically examined it yet, I’m concerned whether there’s an actual infection. I have shared an image for reference. Any guidance or advice on this situation would be greatly appreciated! Thanks in advance!
Managing Blisters Under a Cast
Hello everyone, I'm a 17-year-old and recently fractured my radial head. About a week ago, I was fitted with a plaster cast and a splint. During my follow-up appointment, the medical staff opted to keep my original cast to stabilize the bone, but they wrapped it once more in standard casting material. After a few days of having the initial cast applied, I began to notice some skin peeling and mild blisters forming. This seems to be a result of either the pressure from the cast, sweaty palms, or simply from keeping my hand in a closed position for extended periods. I made the mistake of applying baby powder to my hand, thinking it might help, but it only worsened the situation by making my skin feel sticky and flaky. I raised my concerns about this condition since it has become quite uncomfortable. The doctor who applied the new cast told me that there's not much I can do aside from occasionally cleaning the area with a baby wipe. Additionally, I wanted to mention that I’m a dancer and continue attending classes as best as I can, which may be contributing to the skin issues I'm experiencing. Now, it’s becoming increasingly difficult to close my hand due to the peeling skin and the associated tightness. Any guidance or insight on this matter would be greatly appreciated! 🙏🙏
