Concern Over Petechiae in My 3.5-Year-Old Son

7/31/2025, 9:01:28 PMMale25-34

My child occasionally develops petechiae. When he was approximately 18 months old, I observed a small cluster of petechiae on his neck. We went to the emergency room, where they confirmed it was indeed petechiae. They conducted a blood test, which came back normal, suggesting it might be related to his car seat. Over the last two years, I've noticed sporadic appearances of petechiae in different areas of his body. This morning, however, I found a larger, darker, and more pronounced area of petechiae on his neck. I'm uncertain if this could be caused by some form of friction or irritation. I am conflicted about whether I should consult his pediatrician or visit the ER to request further blood tests. At 3.5 years old, he is otherwise healthy. The sight of this rash raises my anxiety, and I am unsure if I am overlooking a potential concern or if it is necessary to seek medical attention each time he develops a non-blanching rash.

Seeing petechiae on your child can understandably cause concern, especially with a recent episode showing a larger and more pronounced area. Petechiae are small, pinpoint-sized red or purple spots resulting from bleeding under the skin, and while they can indicate various conditions, they are often benign in children.

Explanation

The previous assessment by healthcare professionals suggesting that the petechiae might be related to friction, such as from a car seat, is important. In children, it's not uncommon to see petechiae related to minor trauma or irritation. However, new, larger, or more pronounced areas—especially if they appear suddenly—can warrant further attention to rule out any possible underlying issues.

Next Steps

  1. Monitor Symptoms: Keep a close eye on the petechiae's size, shape, and any associated symptoms (like fever, fatigue, or unusual bruising). Take note of any patterns or triggers.

  2. Document Changes: Since this has been a recurrent issue, consider tracking any occurrences and related activities (e.g., how he was playing or if he had fallen). This information can be helpful for your healthcare provider.

  3. Consult with Pediatrician: Given your son’s overall health and the recent changes in the pattern of petechiae, making an appointment with his pediatrician is the best course of action. They can assess whether further blood tests or evaluations are necessary based on his current situation.

  4. When to Seek Immediate Attention: If you notice an increase in the number of petechiae, significant bruising, bleeding beyond that which is typical (like nosebleeds or bleeding gums), or any changes in your child's activity level or overall health, don't hesitate to seek immediate medical attention.

Your child's health is a priority, and discussing your observations with his pediatrician will provide clarity and reassurance. It's understandable to feel anxious about these changes, so taking these steps can help ensure your son is safe and healthy.

Persistent Forehead Discomfort

Hello, I’m a 29-year-old FTM, and over the last month, I have been experiencing a peculiar sensation primarily located at the front of my head. Instead of a steady ache, it manifests more as a burning, tingling, or numbing feeling, akin to wearing a headband that’s overly tight around my forehead. While it’s predominantly discomforting, there are instances of actual pain. Lately, the area on my forehead and the top of my head feels nearly numb; I can sense touch, but it’s an internal type of numbness, if that makes sense. About two years prior, I received a diagnosis of secondary polycythemia attributed to my testosterone therapy. I faced challenges in securing a therapeutic phlebotomy until the previous month due to insurance complications, and I was ineligible to donate blood because of my POTS condition. However, my POTS doesn’t present with significant symptoms beyond an elevated heart rate, which is managed with metoprolol. Just before I had the phlebotomy procedure, I was experiencing intense burning sensations in my arms and legs, but those symptoms vanished afterward, raising my hopes that the headache would also improve. Headaches are not typical for me, and I’ve tried various over-the-counter medications such as ibuprofen, acetaminophen, and Tylenol without any success. This sensation has been relentless, persisting around the clock. Furthermore, in the last couple of days, I’ve started to notice discomfort radiating into my jaw and cheekbones. My physician initially advised me to stay well-hydrated, suggesting a visit to the emergency room if my symptoms failed to improve. While I’ve attempted to stay hydrated, the prospect of an ER visit is concerning due to my limited financial means. Current diagnoses include POTS and secondary polycythemia. My prescribed medications consist of 50 mg of metoprolol, 0.2 ml of testosterone administered weekly, along with a daily dose of baby aspirin.

Experiencing Severe Headaches and Stomach Pain During Bowel Movements

At 18 years old, I am currently prescribed antidepressants, birth control, vitamin A, and iron supplements. 💀 For quite some time, I've encountered intense headaches and abdominal pain whenever I need to use the bathroom. This issue has persisted since my childhood, often leaving me feeling disoriented for a brief spell—typically just a few minutes. Until today, I thought this was a normal occurrence, but my mom expressed disbelief about my experiences, which has left me feeling quite frustrated. 😭 To share more context: I also have an autoimmune condition known as hidradenitis suppurativa (HS) and have suffered from ovarian cysts in the past.

Should I Be Concerned About Vasculitis?

At 25 years old, I have been dealing with various health issues since I was about 19, initially manifesting as digestive problems and extreme tiredness. After undergoing evaluations, I’ve been diagnosed with Irritable Bowel Syndrome (IBS) and migraines. In August, I noticed tiny, red spots resembling pinpricks on my skin that bled if I rubbed them, which my doctor identified as petechiae, though they don't exactly match the rashes I've seen online. I consulted a hematologist who assured me that I do not have blood cancer and dismissed my concerns (which I already suspected). Earlier this June, I received a diagnosis of anterior uveitis, which, along with my other symptoms, led to further blood tests. Most results appeared normal, with only mildly elevated immature granulocytes and slightly reduced ALT levels. I also tested positive for the HLA-B27 gene. To investigate the possibility of sarcoidosis, I visited a pulmonologist who reported that my lungs appeared to be healthy; my pulmonary function test showed results around 80%, possibly a bit higher. I have a rheumatology appointment scheduled for the end of this month to hopefully gain more insight. Recently, I walked into my primary care office due to persistent chest pain that had lasted around 24 hours; I wanted to ensure it wasn’t a heart-related issue. The EKG results were normal, and after examining the painful area, the doctor inquired about my gastrointestinal history. I mentioned my IBS diagnosis from a few years ago, which led her to refer me to a gastroenterologist whom I have yet to visit. Throughout this ongoing health saga, I’ve experienced intermittent joint pain, severe muscle cramps, and a burning sensation in various locations, notably my right foot and left forearm. Additionally, I have ongoing digestive disturbances, sporadic discomfort akin to a urinary tract infection, fatigue, feelings of depression, back pain, and tingling sensations in my hands and toes. I have also suffered from eight kidney stones, though only one occasion caused substantial pain that necessitated an emergency room visit. My veins have become more prominent than before; I understand some of this can occur with aging. I’ve recently observed a lacy red or purple pattern on my skin, which fluctuates in visibility based on my body temperature. My right ankle has been particularly troublesome, in pain for approximately two months, fluctuating between intense burning, aching, and a sensation akin to water dripping over it. This discomfort is sometimes so severe that even the touch of sheets is irritating, and it worsens with specific footwear or hot showers. I find myself questioning whether I should advocate more strongly for my health or if these symptoms are merely a normal part of aging. I also contend with anxiety, which complicates my ability to discern what constitutes typical discomfort versus something more concerning.

Neck Disc Replacement Insights

Last year, I was involved in a car accident that left me seeking help from a spine specialist. Over time, I have experienced degeneration in two discs in my neck and three in my lower back, a condition worsened by the recent accident. As a result, I have been dealing with numbness, tingling sensations, and pain associated with pinched nerves. The surgeon has suggested replacing the damaged discs with artificial ones. I am reaching out to gather perspectives from both medical professionals and individuals who have undergone this procedure. What are your thoughts about this surgery? If you have had it, how was your recovery process? Have you noticed long-term improvements in your condition? What challenges did you face during your recovery, and did things eventually improve? Are there any important factors I should consider before making my decision? As a male in my early forties who engages in physical labor, any insights would be greatly valued. Thank you in advance for your help!

Unexpected Bumps on Neck and Shoulder Area

Recently, I discovered two small protrusions on the right side of my neck and another on the left, seemingly appearing out of the blue just two days ago. Today, I observed the emergence of two additional bumps: one on the right side of my neck and another located where my neck blends into the shoulder. According to my research, it seems that fatty tumors typically develop gradually; however, these appeared quite abruptly. Their sizes range from approximately 1 to 2 centimeters—relatively small yet visible. A couple of them appear slightly larger, especially if one knows where to look. Should I feel concerned about this? I consulted my general practitioner, who was swift in scheduling an appointment for me in six days. About me: I'm a 20-year-old female, measuring 169 cm and weighing between 50 and 55 kg. I belong to the Caucasian demographic and do not smoke or consume alcohol. Currently, I am being treated with Lamictal at a dose of 25 mg twice daily. Additionally, I take omega supplements and vitamin D regularly.
