SVT Risk in Family History
I would like to share some information about my son, who is 14 months old, a healthy boy, and not currently on any medication. I am curious about his potential risk of experiencing episodes of supraventricular tachycardia (SVT), considering that I, his mother, have been diagnosed with SVT, as well as his paternal aunt. This condition seems to be present on both sides of our family. How much more likely is it for him to develop SVT compared to the general population? I appreciate any insights!

It's understandable to be concerned about your son's potential risk for supraventricular tachycardia (SVT), especially considering your and your family’s history with the condition. While SVT can have a genetic component, the exact likelihood of a child developing it based solely on family history varies and is not precisely quantifiable.
Main Points:
- Family history can increase the risk of SVT, but the exact increase in likelihood is not well defined.
- Healthy lifestyle and regular checkups can help in monitoring heart health.
Explanation: SVT is a rapid heartbeat originating from the heart's upper chambers and can be influenced by genetic factors. Having both a parent and an aunt with SVT suggests some familial tendency, but many individuals with a family history may never develop the condition. Much is still not fully understood about the heritability of SVT compared to other heart conditions.
Next Steps:
- Monitor Symptoms: Keep an eye on your son for any signs of rapid heart rates or unusual behavior, such as excessive fussiness, unusual fatigue, or fainting.
- Discuss with Pediatrician: Schedule regular check-ups with your child’s pediatrician and bring up your concerns about SVT and family history. They might consider evaluating his heart health and could recommend an echocardiogram if deemed necessary.
- Healthy Lifestyle: Encourage a heart-healthy lifestyle as he grows. This includes a balanced diet, regular physical activity, and promoting good hydration.
It's natural to be concerned about potential health issues, especially in children, but staying informed and proactive can help reassure you and promote your child's health. Let me know if you need more information!

Concerns About Neurological Symptoms Before College
Hello, I recently consulted with a neurologist who recommended that I get an MRI/MRA. However, as I'm preparing to head off to college, I'm unsure about when I’ll be able to complete these tests, especially considering the complications I'm having with my insurance. Approximately six months ago, while I was at university, I experienced a sudden and intense headache, often described as an 'ice pick headache.' It was a sharp pain on one side of my head that alarmed me significantly; it persisted throughout the day. After taking some time to relax, the intensity subsided, leaving me with a mild headache afterward. That episode was unique, and I didn’t encounter anything like it again until about a month ago when it returned. Although the pain was manageable—maybe a three on a scale of ten—it still causes me considerable concern. Additionally, a couple of weeks back, I was eating and felt an unusual dryness in my mouth that made swallowing difficult. I had to take sips of water to help facilitate this. Lately, I've also been dealing with headaches—three times a week on average—that feel like migraines or just general dull pain localized to the right side of my head. Alongside this, I have recurring jaw discomfort, particularly on that same side where my jaw often pops. As a child, I underwent a significant amount of dental work to correct my overbite, which leads me to wonder if I'm experiencing symptoms related to TMJ disorder. Touching my masseter muscles reveals some tenderness, although my boyfriend also has similar sensitivity in those areas, so I might be misinterpreting it. I have noticed some neck pain on the same side of my head, which adds to my unease. I find myself worrying excessively about the possibility of a brain tumor, especially concerning my difficulty with swallowing. Yet, I wonder if this anxiety is exacerbating the issue. When I focus on it, I struggle to eat, but on other occasions, I have no issues eating whatsoever. Could this really stem from anxiety or is there a serious underlying concern? During my neurological examination, the neurologist indicated that everything looked fine, noting only a potential small arteriovenous malformation (AVM) as a concern, although I currently don't have the scans needed to confirm this. Summary of symptoms: - Difficulty swallowing, which I’m unsure is anxiety-related since it fluctuates and doesn’t bother me when I’m not thinking about it. - A new shooting headache on one side of my head, plus recurring pressure and migraine-type headaches. Basic info: 19 years old, 5'5", 127 lbs, not on any medications, and no health issues aside from significant dental work in the past.
Struggling with Back Pain: Seeking Advice
I am a 30-year-old woman who has been dealing with intense back pain for nearly three to four months. In an effort to alleviate my discomfort, I've been undergoing physical therapy, chiropractic adjustments, and massages. Unfortunately, basic movements such as bending down are extremely challenging, sitting is uncomfortable, and even walking brings me distress. I've noticed significant weight gain recently due to my reduced mobility, which seems to exacerbate the pain even further. During an MRI that I had for another health concern, there were no findings lower than T1 mentioned in the results. Could this indicate a potential herniation at the L5/S1 level? I also have a history of spondylolysis. If a disc herniation is indeed present, what are the most effective options I have at this stage to resume a normal, pain-free life?
Should I Consider Removing My Skin Tag or External Hemorrhoid?
I've been struggling with this issue for several years now. At times, it can become quite bothersome and uncomfortable, while other moments it barely catches my attention. I've attempted to push it back in, but unfortunately, that approach hasn't worked for me. Now I'm left wondering if it's time to consider removal altogether.
Intense Discomfort in My Upper Right Side
For the past several weeks, I've been experiencing significant pain in my upper right abdomen, which can be likened to a heightened version of a side stitch. I am a 20-year-old female, weighing 210 pounds and standing at 5 feet 3 inches tall. My medical history includes hypermobile Ehlers-Danlos syndrome (hEDS) and a visual impairment. Since March, I've maintained a routine of walking approximately three miles daily without any problems. However, about a month ago, I began to notice what initially felt like a recurring stitch on my right side. At first, it wasn’t alarming until the discomfort started radiating towards my chest. The pain has escalated to the point where it feels as if my right lung is undergoing some form of torment, causing a drastic shift from feeling fine to being nearly overwhelmed by pain. The pain usually begins as a sharp sensation near my lower ribs, then intensifies and transforms into an uncomfortable heat beneath my skin. This leads to bouts of wheezing that make even short walks feel excruciating. A journey that should take a couple of minutes now stretches to about ten when these episodes strike. It seems to have evolved into a persistent problem whenever I am in an upright position. While I understand that side stitches can be quite common, I’m left wondering: is this simply an exaggerated version of that, or do I need to seek medical advice, perhaps even consider an X-ray?
Chronic Ankle Injury Following Surgical Interventions
- Patient Profile: - Age: 53 - Gender: Female - Medications: Daily intake of 20 mg Paxil, with occasional use of pain relief medications such as Zaldiar and infrequent oxycodone. She also takes a range of vitamins and supplements, including fish oil, zinc, and vitamins C, D, and E, along with calcium. - Medical Background: - Previous procedures include ankle fusion, calcaneal osteotomy, and tendon transfer in September 2024. - Complications arose leading to the removal of surgical hardware in November 2024 due to an infection. - She underwent 2.5 months of antibiotic treatment, with a switch from Bactrim due to an adverse reaction to clarithromycin afterward. - The patient participated in extensive hyperbaric oxygen therapy sessions, totaling 60, and is actively receiving specialized wound care, which consists of several debridements and dressings. - Although she does not have diabetes, she has a tendency for delayed wound healing and the formation of scar tissue. - This ongoing issue with her wound has persisted for almost a year following surgery. - Present Condition: - The wound often appears to close but frequently reopens into a small epithelial pit measuring approximately 0.5 mm. - It discharges a clear to yellow serous fluid, especially upon applying pressure or during ambulation. - Currently, there are no signs of odor, fever, or systemic infections, and although there is occasional mild inflammation and swelling, it has not extended beyond the initial area. - Current Treatment Regimen: - Treatment includes the application of various dressings such as calcium alginate, honey alginate, hydrocolloid dressings, along with zinc ointment, Vaseline gauze, and custom compression stockings designed with an opening for the wound. - She is receiving care from both an orthopedic surgeon and a wound specialist. - An ultrasound indicated a potential sinus tract, but the surgeon does not suspect there is an infection in the bone. Inquiry: What might be the reasons for this post-surgical wound remaining open and exuding fluid for such an extended period, especially after treatment for infection and various wound management strategies? Could this prolonged condition be attributed to factors like scar tissue, circulation issues, or possibly a persistent sinus tract that may necessitate surgical intervention? I would appreciate any suggestions regarding potential next steps, such as additional imaging, deciding between surgical or conservative treatments, or exploring circulation therapy options.
