Seeking Guidance on Post-ICD Shock and Seizure Episodes
Greetings, everyone. I am reaching out on behalf of a relative and would greatly value any shared experiences, insights, or recommendations. --- **Patient Details:** - **Age:** 55 years - **Sex:** Male - **Medical History:** Sudden cardiac arrest, first occurrence - **Ejection Fraction (EF):** Currently at 35% - **ICD Status:** Implantable Cardioverter Defibrillator has been implanted - **Angiography:** Conducted 4 days post-cardiac arrest due to fluctuating blood pressure - **Timeframe:** Hospital admission was 18 hours following the cardiac event --- **Incident Overview:** The initial event was a complete cardiac arrest that took place at home. The patient was semi-conscious and was transported to a medical facility after a delay of 18 hours. Due to blood pressure instability, angiography could not be performed immediately and was conducted four days later. An ICD was placed, and he appeared to be making a good recovery initially. --- **Current Challenges (Post-ICD):** Approximately 50 hours following the ICD installation, he experienced an unusual episode that resembled a seizure. During this event, his entire body became rigid, his eyes rolled back, and he was unresponsive for several seconds. An assessment of the ICD logs indicated that it had switched to pacemaker mode, without delivering any shocks. After being gently shaken, he quickly regained awareness and returned to his usual state. Notably, similar episodes of brief unresponsiveness had occurred prior to the ICD placement as well.

Experiencing post-ICD episodes similar to seizures can be concerning, especially after a recent cardiac event. The key points here revolve around understanding the potential causes of these episodes, closely monitoring the patient's condition, and taking specific actions to ensure safety and improve symptom management.
Explanation:
The episodes your relative is experiencing could be related to a combination of factors, including the effects of the ICD, neurological responses, or underlying cardiac issues. Since he has a history of sudden cardiac arrest and has recently undergone significant procedures, it's essential to carefully observe and report these occurrences to his healthcare team.
Next Steps:
-
Monitor Symptoms: Keep a detailed log of the episodes, noting the date, duration, symptoms (rigidity, eye rolling, unresponsiveness), and any potential triggers (e.g., stress, fatigue, medications). This will help healthcare providers understand the pattern and frequency.
-
Safety Precautions: Ensure a safe environment for the patient. If he experiences any further episodes, create a safe space for him to fall without injury. Consider having someone nearby during activities that may provoke a seizure-like response.
-
Hydration and Diet: Encourage the patient to stay well-hydrated and maintain a balanced diet. Low blood sugar or dehydration could contribute to episodes of unresponsiveness.
-
Medication Review: If the patient is on any new medications or has changes in dosages, review these with the healthcare team, as they may affect how he responds neurologically.
-
Follow-Up Appointment: Write down key observations and concerns to bring to the next medical appointment, particularly the experience of brief unresponsiveness and how the ICD has been functioning.
-
Emergency Plan: Develop an action plan for when these episodes occur. If he becomes unresponsive again or experiences additional unusual symptoms (like increased heart rate or chest pain), knowing when to seek immediate medical care is crucial.
It’s important to approach this situation with care and keep communication lines open with healthcare providers for any changes or new symptoms. Most importantly, reassure your relative that monitoring and taking these steps can help manage his health effectively.

Seeking Guidance on Managing Post-Abcess Wound
I am looking for insight regarding a wound resulting from a ruptured abscess that occurred a few months ago. Although I intend to consult a wound care expert soon, I want to ensure the wound is healing properly in the interim and that my treatment isn’t exacerbating the situation. Your thoughts, advice, or suggestions would be greatly appreciated. I took several photos recently, including one of a red spot that I captured just yesterday. Normally, the appearance is that of a red, raised mark. My primary concern involves the small red dot and the yellow discharge evident from the wound. This condition has persisted since January 2025 and I am unsure if it indicates an infection or something else entirely. The yellow discharge is somewhat stringy, reminiscent of the texture of saliva that accumulates in the mouth overnight. As for my care routine, I currently use a bordered adhesive bandage and apply a light layer of Neosporin to prevent the bandage from adhering directly to the wound. Bacitracin caused irritation, so I decided against that. While I’m considering switching to Vaseline, I have stuck with Neosporin, as it proved effective so far. I cleanse the area daily in the shower using mild soap and water to maintain cleanliness. Occasionally, I inadvertently touch the red spot, which I suspect is hypergranulation, and that leaves me sore for hours. I do have Bactine available to use, which might be beneficial. I have also recently started using thicker foam gauze to help manage the drainage, which seemed to alleviate some discoloration, but it appears that I am now experiencing increased drainage, which has darkened in color. A little background: The abscess ruptured on its own at the end of January this year and has been a slow heal. After conducting extensive research to properly care for it, I've encountered various methods, leading to a fair amount of trial and error. Located beneath the labia, the wound poses a challenge for bandaging (though I have developed a system). I must frequently change the bandage, especially after bathroom visits, to prevent contamination from urine. Additionally, I sought advice regarding wound and healing care at an urgent care facility and from another physician, yet they did not provide any information or indications of warning signs without a follow-up visit, which I could not afford at the time. I was prescribed antibiotics for just two days before the abscess ruptured and then given antibiotics for about a week afterward, which I had to request myself.
Persistent Skin Rash and Mild Itching: Seeking Advice
I’ve been dealing with a skin rash for about 24 weeks; while it’s mostly just a mild itch at times, it seems to be gradually spreading. Initially, the rash appeared only on my breasts, but it has now extended to my back, arms, and across my torso. Although it’s not particularly uncomfortable, the cosmetic aspect is becoming more concerning. When I consulted a physician, the rash was still localized to my breasts. He suggested it resembled the early stages of pityriasis rosea, though he couldn’t provide any definitive answers. He advised me to monitor the situation. Would it be wise to schedule another appointment?
Concern about Lip Condition in My Toddler
My daughter, who is 2 years old, has been showing a concerning issue on her upper lip since this morning. This is her first time experiencing such a condition, and she has never had a cold sore before. To our knowledge, she hasn’t been in close proximity to anyone with an active outbreak. Although my father occasionally deals with cold sores, he maintains his distance when he has them; his last occurrence was a few weeks back, which makes me somewhat uneasy about the situation. Apart from this lip issue, she's been relatively healthy, only experiencing mild symptoms of a cold, including a runny nose and a cough. I’m trying to determine whether what she has is simply irritated skin or if it could indeed be a cold sore. My anxiety is heightened as I have another young baby at home. Just yesterday, my toddler managed to plant a kiss on the baby before I could intervene, which adds to my worries.
Questioning My Pituitary Lesion’s Impact on My Health
I’m a 23-year-old female with a noteworthy lesion on the posterior left side of my pituitary gland, measuring 11mm in width, 8mm in height, and 6mm in depth. The radiology report indicates that my infundibulum is midline but truncated as a result of this lesion. Staying active is essential to me; I typically engage in weight lifting and workouts around five days each week, performance permitting. My height is 5’6” and I weigh approximately 160 pounds, although my weight has varied between 148 and 168 over the last eight months. My physically demanding job has become increasingly challenging. I experience a range of symptoms, such as: - Extreme fatigue - Hair loss - Migraines originating from the left side of my head, specifically behind my left eye and at the base of my skull (these are new for me) - Numbness and tingling in my face and left arm during severe migraine attacks - Occasional blurred or double vision - Altered body odor and perspiration levels - Vertigo - A sensation of a lump in my throat (I suspect this is linked to my pituitary lesion and thyroid issues, although my thyroid levels appear normal). Despite my efforts to communicate these concerns to medical professionals, my neurologist insists that my condition is symptom-free. The imaging report hints at possibilities including hemorrhagic pituitary microadenoma, pituitary apoplexy, or proteinaceous material within a Rathke cleft cyst, among others. I have an appointment with an endocrinologist lined up and aim to seek another neurological opinion as well. However, I find myself questioning my own sanity. I’m in constant discomfort, struggling to gather the energy for daily tasks, and enduring migraines that mimic stroke symptoms weekly. The debilitating pain and pressure behind my left eye are distressing almost daily. As I prepare for my upcoming endocrinologist appointment, I’m unsure how to organize my thoughts and articulate my feelings properly. All my recent DICOM files have been sent, but I want to ensure I present my situation clearly. I have been experiencing pain continuously since I was 15 years old. Each time I voice my concerns, I can’t shake the feeling of being dismissed due to my age, fitness level, and apparent health. Should I discontinue any supplements ahead of blood tests? Is fasting required? Should I request particular tests? What’s the best way to track my headaches or energy fluctuations? Any recommendations would be appreciated. Additional Information: - Diagnosed with a pituitary cyst/adenoma (my doctor hasn’t specified which, nor do I fully understand the difference), ADHD, recurrent depression (currently in remission), lumbar/thoracic spondylosis, and cervicalgia in the occipito-atlanto-axial region. - Medications/Supplements: I currently take methylphenidate (Concerta, 27 mg CR), spironolactone (100 mg for acne), sumatriptan (50 mg for migraines, though it isn’t very effective), IUD (Liletta, placed August 2024 after replacing Kyleena from 2019), Xyzal (5 mg for seasonal allergies), magnesium, omega-3 fatty acids, vitamin D (2000 IU), vitamin C, vitamin B12 (suggested in my last appointment), vitamin A, and L-lysine (1000 mg, recommended for cold sores). Possibly relevant details include receiving trigger point injections for headache relief. The initial treatment yielded positive results, addressing neck tension, but subsequent sessions offered little benefit. In April 2024, I suffered a concussion and corneal abrasion from a workplace accident, which I initially believed to be the source of my ongoing pain and neck problems. However, the emergence of severe sleep disturbances and the discovery of the pituitary lesion shifted my focus. Though my primary care provider has assessed my thyroid function and inflammatory markers, results showed normal levels. I suspect these assessments may not have been thorough enough based on my limited research. I am more than willing to provide further details. I have posted additional information in a different subreddit that may illuminate my situation more clearly if needed.
Concern Over Unusual Brown Spot on Scalp
Hello, I’m a 19-year-old female and my health is generally good, with the only medication I take being birth control. Recently, I noticed two brown spots on my scalp that resemble freckles or possibly moles, and I’m curious about what others think. Context: Skin cancer runs in my family, which makes me vigilant about sun protection. I consistently apply sunscreen and wear hats to shield myself from UV rays. I don’t have many moles or freckles and have never tanned indoors. The spots are located under my hair and haven't received much sun exposure. A few months back, I experienced seborrheic dermatitis in this area, resulting in yellowish flakes. After visiting a dermatologist, I was prescribed a medicated shampoo, which effectively resolved the issue. Since then, I’ve monitored the area without any signs of recurrence. I only recently discovered these brown spots, likely having emerged within the last week or two. Initially, I thought they might be seborrheic keratosis, but they don’t have a raised or flaky texture, and I can’t feel them when I touch my scalp. I have experienced occasional mild headaches in that region, though I’m uncertain if these are related to the spots. I understand that diagnosing skin conditions through a photograph can be challenging, but I would greatly appreciate any insights, particularly if this seems like an issue that warrants professional evaluation!
