Seeking Guidance on My Son's Health Concern
My son is a 3-year and 6-month-old boy with a concerning health issue. For the last four months, he has had an invisible yet noticeable itchy lump on the lower left side of his thigh. Although this lump is not causing him any pain, it has raised some concerns for us. **Previous Evaluation Report (3 Weeks Ago)** A soft tissue ultrasound was conducted due to the lump's presence. The ultrasound history indicated that the lump in the distal lower thigh was hard to the touch and possibly immobile, making it uncertain whether it originated from muscle or bone. The results revealed a hypo-echoic mass in the anterior section of the left thigh that displayed certain vascular characteristics. This mass measures about 7 x 4 x 12 mm and is located approximately 3 mm beneath the skin's surface, with some echogenic areas visible within. Additionally, an X-ray of the left femur indicated that the patient’s skeletal maturity is still developing and showed no abnormal bony lesions. **Conclusion from Report**: The concerns regarding the soft tissue area indicate that it does not impact the bone and appears solid with some vascularity. The presentation is atypical for a lymph node, leaving open the possibility of a soft tissue tumor, although the exact tissue origin remains indeterminate. **Recent Ultrasound Findings (3 Days Ago)** An ultrasound was performed again, this time focusing on the left thigh's anterior region due to reported pain. **Comparative Evaluation from June 10, 2025**: The findings revealed a heterogeneous hypo-echoic lesion measuring 3 x 8 x 5 mm, which has reduced in size from the previous assessment (12 x 7 x 4 mm). It retains internal echogenic features and vascularity within the area's subcutaneous tissues. **Summary of New Findings**: The lesion remains a non-specific vascular soft tissue anomaly, potentially identifiable as a reactive lymph node or an angioleiomyoma, a benign tumor. A follow-up ultrasound is suggested in three months for further evaluation. After researching angioleiomyoma, I found that it predominantly occurs in adults and typically presents as a visible, painful lump, rather than as an itchy and invisible one, which my son is experiencing. Currently, we are awaiting an MRI, but the wait is projected to extend beyond four months. I am contemplating whether a biopsy would be advisable given my ongoing worry about the possibility of soft tissue sarcoma or lymphoma. An earlier report dismissed involvement of lymph nodes, yet the recent ultrasound introduced the idea of a reactive lymph node. This lump has persisted for over four months, is palpable but not visibly apparent, and is notably aggravated when my son scratches it. I would greatly appreciate any advice or insight into this situation.

Thank you for sharing your son’s health concern; managing uncertainty about his health can be very stressful for you as a parent. The situation you described, with the lump being monitored through ultrasounds and possible benign characteristics, does warrant careful consideration. Here are some essential points and suggestions regarding your son’s condition:
Summary of Key Points:
- Ultrasound Findings: The ultrasound indicated a hypo-echoic mass with vascular features, with a significant reduction in size since the initial evaluation.
- Possible Diagnosis: Although there are suggestions towards possible benign origins (like a reactive lymph node or angioleiomyoma), ongoing monitoring and evaluation are crucial.
- Next Steps: You’re awaiting an MRI, and there's a concern about the necessity of a biopsy due to the prolonged nature of the lump's presence.
Explanation:
The lump your son has appears to have benign characteristics based on the ultrasound evaluations, particularly since it has reduced in size. Angioleiomyomas, while more common in adults, can also present in children but are typically engendered from smooth muscle tissue, which is benign. The vascularity and echogenic qualities observed might suggest a reactive process rather than a malignant one, especially since the growth rate is slow.
Given that the lump is itchy and grows more noticeable when scratched, it could also indicate some irritation against the skin, rather than an aggressive process. However, your valid worries regarding the potential of soft tissue sarcomas or lymphomas should not be dismissed.
Actionable Next Steps:
- Ongoing Monitoring: Keep a close check on the symptoms. Note any changes in size, shape, or sensation of the lump. This can guide future discussions with healthcare providers.
- Skip the Biopsy for Now: Unless his pediatrician strongly recommends it based on impending changes, wait for the MRI results to provide more clarity. A biopsy might be more informative after imaging provides clearer guidance on what the mass may represent.
- Control Itchiness: To alleviate your son's discomfort, consider gentle moisturization around the lump with a fragrance-free lotion and encourage him to avoid scratching, as this can irritate the area further.
- Follow-Up: Plan to discuss the MRI results with his pediatrician comprehensively, focusing on any new findings and the final recommendations for management.
Emotional Support:
It's understandable to feel anxious during this period of uncertainty, especially when it involves your child's health. A waiting period can bring about worry, but staying connected to your healthcare provider offers the best pathway for addressing your son’s well-being. Make sure to discuss any immediate concerns with his doctor if you notice significant changes.
Please continue to trust in the evaluation process, and remember that care teams are equipped to handle these types of cases competently. Let me know if you have any further questions or need more information.

Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
