Concerns About Petechiae on My 3-Month-Old
This evening, I discovered that my 3-month-old son, who was born prematurely at 34 weeks and experienced intrauterine growth restriction (IUGR), had petechiae visible under his chin and along one side of his jaw while he was feeding. I reached out to his pediatrician immediately, but it was already past 9 PM. I have been monitoring his temperature diligently, and he hasn't developed a fever. Earlier today, he had been fussier than usual. To provide some context, I had undergone surgery a week ago, which meant he was on formula alone for approximately 36 hours. His usual feeding routine consists of half 24 calorie Neosure and half breast milk. During the formula-only period, he was especially cranky in the evenings and consumed only 2 to 2.5 ounces instead of his normal intake of 3.5 ounces. Once I reintroduced breast milk, his fussiness improved, but around day five following my surgery, he became gassy and returned to consuming only 2.5 ounces. I attributed this to a recent switch in his nipple size from preemie to level 1, so I changed it back to a transitional nipple. Since then, he has consistently consumed between 2.75 and the full 3.5 ounces over the last 24 hours. However, during his 6 PM feed, he showed significant fussiness and only drank 2.5 ounces, prompting me to administer Mylicon drops. Just before his 9 PM feed, he seemed extremely hungry and became quite agitated while awaiting his bottle to warm. He was making a high-pitched scream, turning purple, and seemed to be losing his voice while thrashing in my arms. Once fed, he eagerly finished his usual 3.5-ounce bottle and promptly fell asleep. Later, he completed his nighttime feeding of 3.5 ounces with minimal intermittent fussing due to gas. In my research about petechiae, I learned that it can be associated with meningitis; however, he displays no fever, stiffness in the neck, or bulging fontanel. He has been fussy intermittently and has not consistently completed his bottles. It’s now 2 AM, and upon checking again with a flashlight, I observed a few singular dots near his eyes, on his nose, and around his chest and neck area. It is unclear whether I simply missed these earlier or if this condition is worsening. I also wonder if the petechiae could have resulted from him straining during his distressing episodes of crying. I am uncertain whether I should wait until morning for further guidance or take action now, especially since the last two feeds he completed fully, despite previous eating inconsistencies.

It's understandable to be concerned about petechiae on your 3-month-old son, especially given his medical history and recent changes in his feeding patterns. Here's a breakdown of the situation and recommended steps you can take.
Main Points
Petechiae can arise from various causes, and in infants, they warrant careful observation. Given your son's recent feeding difficulties, fussiness, and history, it's crucial to monitor him closely. While it may be tempting to wait until morning, your son’s current symptoms suggest that further action may be needed.
Explanation
Petechiae are small, pinpoint red or purple spots caused by bleeding under the skin. They can appear for many reasons, including normal crying due to straining or potentially more serious issues, such as infections or coagulation disorders.
Given your description:
- Lack of Fever: This is reassuring, as systemic infections often present with fever.
- Recent Fussiness and Feeding Changes: Your son has had feeding inconsistencies, which may contribute to distress but are also important to consider.
- High-Pitched Crying and Distress: This can indicate discomfort or pain, particularly if associated with feeding difficulties.
Next Steps
-
Immediate Assessment:
- Reassess Symptoms: Monitor your son closely for any changes. Look for additional petechiae, signs of fever (even low-grade), persistent fussiness, or changes in responsiveness.
-
Document Findings:
- Keep a Record: Note how many petechiae you see, their size, and any new symptoms (like increased fussiness or feeding inconsistencies) throughout the night. This information can be helpful for the pediatrician.
-
Feeding Considerations:
- Continue to Feed as Normal: Ensure that he is fed according to his typical routine and watch for any difficulties during feeding.
- Continue to Use Comfort Measures: If he appears gassy, keep using Mylicon or similar remedies, ensuring baby is comfortable during feedings.
-
Seek Immediate Care:
- If you notice any new concerning symptoms, such as:
- Increased petechiae or a new rash
- Sudden behavior changes (more lethargic, not responding as usual)
- Significant fussiness that seems unmanageable
- Signs of severe distress (persistent crying, difficulty breathing)
- Contact your pediatrician or go to the nearest emergency room for further assessment. While it's essential not to panic, ensuring your son is safe and any serious issues are quickly identified is crucial.
- If you notice any new concerning symptoms, such as:
Conclusion
While many cases of petechiae may be benign, given your son's age and recent health changes, it’s advisable to remain vigilant and reach out for professional guidance as needed. Your prompt attention to his symptoms is commendable, and keeping an eye on him will be beneficial. If you have any ongoing concerns overnight, don’t hesitate to seek help.

Recovery After Blunt Abdominal Trauma and Adhesions
Hello everyone, I experienced a significant impact to my abdomen on Sunday and am currently grappling with considerable discomfort and fatigue. After seeking assistance at a walk-in clinic on Monday, a nurse suggested that I might be suffering from internal bruising. Subsequently, during a consultation with my general practitioner today, it was indicated that the trauma could have potentially displaced my existing adhesions. For context, I have been diagnosed with Irritable Bowel Syndrome (IBS) and have a history of surgeries, including an emergency laparotomy due to a ruptured appendix. During that procedure, my bowel was also compromised and required repair. I have previously undergone diagnostic laparoscopy and adhesiolysis to address significant abdominal adhesions located midline and extending downwards, affecting my Douglas pouch and right ovary. However, the surgeons opted not to address adhesions above the umbilicus owing to the increased risks of complications involved. Currently, I’m adhering to my healthcare provider's recommendations, which primarily include resting and managing pain with paracetamol and buscopan. Given the specificity of my situation, I find it challenging to locate reliable resources for guidance on this issue. I’m hoping to reach out to the community to see if anyone has expertise or personal experiences to share regarding recovery after such events. Additionally, are there recommended practices or activities that might facilitate a more effective recovery process?
Seeking Insight on Recent Symptoms
I am a 29-year-old female currently undergoing treatment with azathioprine, hydroxychloroquine, and citalopram. My medical history includes diagnoses of Sjögren's syndrome, obesity, and depression/anxiety. Today, I noticed some red spots developing on the roof of my mouth. While they aren't particularly painful, they do cause a degree of discomfort. In the past, I have experienced mouth ulcers due to Sjögren's, but those were characterized by white patches with red borders, making these spots distinctly different. Since starting my immunosuppressive medication, I haven’t had any other sores. Additionally, there is no pain or soreness in my throat at this time. Although I don't feel feverish, my thermometer is currently inoperative, leaving me uncertain about my temperature. I wonder if this could be a viral issue? I'm hoping it is something manageable at home. I’ll be sharing an image in the comments for reference. I would greatly appreciate any insights you may have!
Seeking Clarity on My Health Issues
Hello and thank you for taking the time to read my message. I am a 36-year-old female, standing 5 feet 7 inches tall and weighing 177 pounds. I do not smoke. Currently, I am on several medications: - Atenolol for heart palpitations - Trazodone for sleep issues - Buspirone to manage anxiety - Effexor for both anxiety and depression - Rizatriptan for migraines For the past year, I've been facing a challenging array of health problems. These include night sweats, trouble sleeping, persistent migraines, fatigue, depression, anxiety, gradual weight loss, hair thinning, and joint discomfort. Unfortunately, these issues seem to be intensifying. Notably, my symptoms appear to correlate with my menstrual cycle. As I finish ovulating, I start experiencing night sweats, which significantly disrupt my sleep to just 3-4 hours a night. This lack of rest contributes to my frequent migraines. When my period begins, the night sweats cease, my mood stabilizes, and I enjoy about 10-12 days where I feel relatively normal, although I still deal with mild headaches and some lingering fatigue. However, once ovulation occurs, I find myself back at square one. I attempted using hormonal birth control, but it worsened my migraines to an unbearable degree, prompting me to discontinue that medication. I’ve undergone various lab tests, including a TSH test, which returned normal results. The only notable finding was a notably elevated platelet count of 505. This has been consistently high for years, and a previous doctor indicated it was not a concern. Currently, my primary care physician is referring me to both an obstetrician and a hematologist due to her uncertainty regarding my condition. I find myself utterly drained. The toll on my work life is significant, compounded by a substantial loss of hair. The earliest appointment with the obstetrician is in October, and I have yet to hear from the hematologist. If anyone has suggestions or insights that could assist me in discussions with my PCP, I would greatly appreciate it. Please feel free to ask any questions you may have. Thank you once again for your attention.
Bizarre Lump Seems to Shift Between Wrists
I’m a 35-year-old man weighing 235 lbs, and I’ve been dealing with issues in both wrists for several years now. My medical history includes treatment for depression, anxiety, high blood pressure, and gastrointestinal discomfort, for which I take bupropion, buspirone, losartan, and omeprazole. A few years back, I noticed a peculiar lump forming on my left wrist. If I recall correctly, its emergence coincided with an exercise-related injury; a particularly painful push-up seemed to trigger its development. This lump is quite sensitive to pressure and has been associated with joint weakness and discomfort. Activities that put strain on that wrist, like playing the guitar, would lead to intense soreness the following day. After a visit to my primary care physician, it was identified as a ganglion cyst. I was then sent to an orthopedic specialist who barely examined it, merely acknowledged the cyst diagnosis in my records, and advised there was nothing to be done since surgical intervention could risk nerve damage. The recommendation was simply to cope with it. That appointment took place back in January, and surprisingly, the lump has been gradually diminishing! I didn’t notice the exact moment it started to fade, but now, as of July, it seems to have entirely vanished. Oddly enough, I’ve noticed a similar lump developing on my right wrist in the exact same spot! I’m curious about the possibility of cysts appearing in such unusual patterns. Is it normal for one to seemingly "move" from one wrist to another like this? Can I anticipate that the new one will also disappear in time? Could there be an alternative explanation for this phenomenon? Am I possibly injuring a tendon in that area? Cheers!
Is It Just Peroneal Tendonitis or Something More Serious?
As a recent 22-year-old college graduate, I've always identified as an athlete. However, during my final year at university, I let my fitness routine slip a bit, resulting in some unwanted weight gain. To change that, I began running around six weeks ago. Initially, everything was going quite well; I was completing runs of 2 to 4 miles, three to four times a week. My pace was improving, and I felt physically strong. However, I made a spontaneous decision to participate in a 10K event, which I surprisingly managed well. I didn’t experience much soreness afterward, but that relief was short-lived. The following morning, I woke up with a persistent, bruise-like discomfort on the outer area of my mid-foot. While resting eased the pain, stepping on it was extremely uncomfortable. Concerned, I visited a nearby urgent care where I underwent x-rays to eliminate the possibility of a stress fracture. Fortunately, the results showed no fracture, and the attending physician diagnosed me with a sprain, suggesting a period of rest. Unfortunately, and perhaps somewhat foolishly, I opted for only a week of rest before attempting to run again. I convinced myself I was ready since the pain had diminished enough to make walking tolerable. Testing my foot turned out to be a poor decision. That run occurred five days ago, and since then, I've found myself limping around awkwardly. The discomfort, which initially resided in the sole of my foot, has now extended beneath my ankle bone and above the mid-foot area. I’m still unable to bear my full weight on it; although I've noticed some slight improvements in mobility, the pain, while less severe than the original episode, makes me suspect that this injury could be more complicated than mere tendonitis. Is it normal for pain to escalate to this level? From previous encounters with tendinitis in my elbow due to baseball, I can say that this experience has been far more intense and troubling than anything I've faced before.
