Toddler Experiencing Significant Neck Swelling

2/11/2026, 12:00:52 AMMale25-34

I will post a picture in the comments later. My son, aged 2 years and 3 months, has a height above average for his age and weighs 30 pounds—he’s not overweight. Currently, one side of his neck is extremely swollen. His medical history is clear of any chronic conditions and he is not on any medications. Should I take him to the emergency room, or is it safe to wait until tomorrow? While he is generally cheerful and does not have a fever, he does complain of pain when the swollen area is touched.

Immediate attention to neck swelling in a toddler is important as it can indicate various conditions. Given your son's symptoms, it’s essential to assess the situation carefully.

Main Points:

  • Neck swelling in a toddler can suggest infections (like lymphadenitis), inflammation, or even a possible abscess. The fact that he is in pain and has significant swelling is concerning.
  • Observation is important, but early intervention may be necessary depending on certain symptoms.

Explanation:

The swelling on one side of your son's neck could be due to several reasons, including:

  • Infections: Such as a viral or bacterial infection affecting lymph nodes.
  • Abscess: A pocket of pus that can develop due to an infection.
  • Trauma: Sometimes minor trauma can lead to localized swelling.

The fact that he is cheerful and doesn't have a fever is a positive sign; however, the pain upon touching the swollen area is a signal that something may not be right and needs evaluation.

Next Steps:

  1. Evaluate Additional Symptoms: Keep an eye on any changes, such as:
    • Difficulty swallowing or breathing, which would require immediate attention.
    • Any development of fever later on.
  2. Manage Pain: If he seems uncomfortable, age-appropriate doses of children's acetaminophen (as per instructions) can help ease pain.
  3. Do Not Delay Beyond Tonight:
    • If there is no improvement by tomorrow, or if symptoms worsen, visit a healthcare provider for an evaluation.
    • If you notice severe symptoms (like high fever, trouble breathing, or inability to drink fluids), go to the emergency room without delay.
  4. Monitoring: Keep a close watch on the swelling and his overall behavior to note any significant changes.

Providing a supportive, calm environment will help him feel better during this time. Please feel free to update if you have any further concerns.

Elevated Liver Enzymes: Preparing for My Follow-Up Test

Recently, I underwent a blood test and the nurse informed me that my liver enzymes were slightly above the normal range. To be honest, I haven’t prioritized my health over the last several months, neglecting exercise and indulging in an unhealthy diet, compounded by excessive drinking just before the test. I had been drinking quite a bit the weekend prior and again on Sunday, while the test was on a Tuesday. Since that time, I’ve completely cut out alcohol and have committed to a healthier eating regimen, and honestly, I’m feeling quite good. Thankfully, I haven't experienced any of the symptoms often mentioned, such as abdominal pain, jaundice, or swelling. However, the lab results were definitely concerning, and I won’t pretend otherwise. I have my follow-up blood test scheduled for tomorrow, so I’m reaching out for advice on how best to prepare for it. Thank you!

Experiencing Unusual Symptoms After HFM: A Personal Journey

I always viewed myself as someone who maintained good health and fitness. My daily routine involves working outdoors, and I avoid alcohol and tobacco. However, in early 2025, I contracted hand, foot, and mouth disease from my two-year-old child. This illness persisted for an exhausting seven weeks from April to May. I endured severe ulcers that prevented me from eating for several days and faced painful blisters that covered my hands, feet, and groin. Eventually, the skin on both my palms and the soles of my feet peeled away completely. The culmination of this ordeal resulted in epididymitis, leading to an alarming swelling of one of my testicles, which measured 36ml. Despite a hospital stay, the doctors assured me that recovery would take weeks, yet I still feel a lingering difference. By June 2025, I suffered a lower back injury from overexertion and fatigue, a recurring issue in my life. Normally, I would recover swiftly from such injuries, but this time was different. Bending or lifting became unbearable due to intense pain, and I began to experience sciatic discomfort in my left leg. Additionally, my foot would frequently feel numb, making it difficult to stand or sit for extended periods. After consulting with doctors, I was given a diagnosis of a possible slipped or herniated disc and prescribed Celecoxib to manage inflammation. Throughout the summer, I pursued various treatments, including physiotherapy, chiropractic sessions, and acupuncture. Despite months of strength training, stretching, and techniques like dry needling and nerve flossing, I still felt a sharp stabbing pain in my lower back and sacral region. Another doctor speculated that I might have a partial tear in my anterior longitudinal ligament, but healing seemed uncertain and would require patience. As September rolled in, I awoke with a severe kink in my neck, which plagued me through numerous sleepless nights, leading to physical weakness and peculiar sensations. I discovered that I could no longer contract my right serratus anterior muscle, which had been a defining feature of my physique since my early teenage years. I struggled to lift my right arm overhead and was diagnosed with scapular winging. Following this diagnosis, my doctor prescribed Pregabalin and referred me to a neurologist in December. The neurologist explained that my nervous system had essentially turned on itself to combat the infection, a scenario he noted wasn't entirely uncommon. During my visit, he illustrated the nerve activity in my surrounding muscles, revealing that while my serratus nerves were active, their firing rate was significantly low. He advised against surgery since it had already been six months since I first noticed the muscle weakening, but warned that if I didn’t see improvement by June 2026, surgery to attach my shoulder blade might become necessary. He also indicated that physiotherapy might not yield much benefit in this situation. Recently, I woke up with yet another painful kink in my neck. For four days now, I've been experiencing pins and needles in my right arm and wrist. Currently, I am awaiting an MRI appointment. I apologize for my lack of medical terminology; I am just trying to understand whether my symptoms could be related to the hand, foot, and mouth disease, how to express this concern to my doctor, and what specific tests I should inquire about. With a young family to support and daily labor to endure, I appreciate your time and any advice you might be able to provide.

Inquiries about Papilledema

At 24 years old, I recently underwent my annual eye examination, where the optometrist identified some swelling in my eyes. Consequently, the doctor provided me with a referral (see attached) and mentioned that it could take one to two weeks for me to receive a response from the specialist’s office. He advised that if I do not hear back within that timeframe, I should reach out directly to arrange my appointment. Additionally, he cautioned that I should visit the emergency room if my symptoms worsen. I am seeking further information regarding this issue.

Should I Consult My GI Specialist About Mild Active Crohn's Disease?

Greetings! I've been dealing with recurring high-grade obstructions in my small intestine, particularly at the same location in my terminal ileum, as highlighted by CT scans over the years. Each time I undergo colonoscopies or CT imaging, the inflammation tends to resolve post-blockage, and has not been evident in the most recent MRI I got from my gastroenterologist. This MRI indicated that there is a short segment of the terminal ileum that is slightly thickened and demonstrates hyperenhancement after receiving gadolinium contrast. According to the report, these observations are suggestive of mild active Crohn's disease. Fortunately, there were no signs of fistulas or strictures present. Additionally, a limited area of diffusion restriction was detected within the terminal ileal portion, with some minor thickening of the wall measured at 0.4 cm along a segment that spans around 7 to 10 cm. Although there is hyperenhancement in that segment, again, there is no indication of strictures or the formation of fistulas. On a positive note, the other parts of the small intestine appear normal, and no abnormal thickening or pathological lymph nodes were identified in the visualized colon. I’ve yet to discuss these MRI results with my gastroenterologist. Given that the findings are rated as mild, should I still reach out to him? Or is it best to refrain from contacting him since mild cases may not warrant treatment?

Elevated ALP Levels: A Long-Term Concern

Hello everyone. I'm a 23-year-old assigned female at birth, weighing 195 pounds and standing 5 feet 2 inches tall. Lately, I've been grappling with various health problems. I stumbled upon lab results from two years ago that included full metabolic panels taken six months apart. Surprisingly, my primary care physician overlooked the significantly high ALP levels, which were recorded repeatedly at over 155. It's important to note that my weight back then was lower, and I had gained weight due to a misdiagnosis of bipolar disorder by an unreliable psychiatrist, for which I was prescribed Seroquel for two years. Currently, I'm not on any medications except for an albuterol inhaler for my asthma, so I doubt my ALP issues stem solely from my weight, despite my parents' insistence. Most recently, I underwent testing because of irregular menstruation and adverse effects from my birth control shot, which caused prolonged menstrual bleeding for nearly two months. Multiple tests indicated I am quite anemic, along with low levels of SHBG, while other hormone levels appeared normal. Furthermore, I have deficiencies in vitamin B12 and D, which I will delve into regarding my dietary habits shortly. But again, the ALP level caught my eye – it was recorded at 146. In the last month, I've had to visit the emergency room three times due to severe vomiting, stomach cramps, and constipation. Initially, I suspected a return of my ulcers, which led an assistant at my primary's office to prescribe me Omeprazole 40mg. However, after my trips to the ER, I discontinued it. On the first two visits, I was given Ondansetron 8mg at two different hospitals. When that didn't help, another ER switched my medication to Metoclopramide 40mg. A week later, during a gastroenterology appointment, the doctor stopped the Metoclopramide and reinstated Omeprazole 40mg, while also introducing a propylene glycol drink mix to assist with digestion. Thankfully, following a diet of straightforward meals—comprising proteins, carbs, and cooked vegetables—I've stopped vomiting. I'm convinced that my low iron, vitamin B12, and vitamin D deficiencies are consequences of my recent eating habits, which have been further complicated by heavy menstrual bleeding. Yet, what troubles me the most is the elevated ALP level. I've been experiencing persistent fatigue and excessive hunger for a few months now, dating back to before the vomiting and bleeding began. It feels like something inside me is depriving me of nutrients, leaving me constantly unsatisfied. Despite my efforts to maintain a positive outlook, the situation is frightening, especially since no one has addressed the high ALP levels with me until now. It was the gynecologist’s assistant who mentioned that elevated ALP could be linked to menstrual irregularities. I thought it wise to reach out to this community rather than spiral into despair from googling my symptoms. I would prefer to hear directly from individuals who can either provide reassurance that I will overcome this challenging period or offer insights if this could indicate a more serious health concern.
