Concerns About Cold Sores Transmission
As a 26-year-old woman, I've dealt with cold sores for as long as I can recall, and I recently experienced another outbreak. I'm extremely cautious about avoiding close contact like kissing, as well as not sharing items with my spouse or children. To prevent these outbreaks, I take a daily dose of valcyclovir, in addition to medication for my depression and OCD in the form of Zoloft. I suspect I may have missed my dose of valcyclovir yesterday, although I did take it today around half an hour before the incident occurred. I vape, but the device was turned off at the time. Unfortunately, my 10-month-old managed to grab it and put it in her mouth. I had just used it five minutes earlier, and it escaped from my pocket. Once I noticed what she was doing, I quickly retrieved the device and cleaned her mouth. I'm feeling incredibly anxious and guilty as a parent. Is there a significant risk that she might develop cold sores now? Is this a certain outcome?

It's understandable to feel anxious about your child's safety, especially in situations concerning contagious conditions like cold sores. Fortunately, the risk of your 10-month-old developing cold sores from the incident you've described is very low.
Main Points
- Cold Sores and Transmission: Cold sores, caused by the herpes simplex virus (HSV), are primarily transmitted through direct contact with the virus, often via kissing or sharing items.
- Risk from Vaping Device: The likelihood of the virus being transferred from a vaping device to your child is minimal, especially if the device was not actively used at that moment and if proper hygiene was practiced after you noticed.
Explanation
Cold sores are contagious, particularly when the sore is active. However, your child would typically need direct contact with the sore or the saliva of an infected person to acquire the virus. Since you cleaned her mouth promptly and the device was off when she took hold of it, the chances of transmission are very low.
Next Steps
- Monitor for Symptoms: Keep an eye out for any signs of cold sores or fever. Symptoms in infants can include fussiness or irritability, but they are very unlikely to develop from this situation.
- Hygiene Practices: Continue to maintain good hygiene practices by cleaning surfaces and not sharing personal items. If an outbreak occurs, be especially cautious about contact with your child.
- Reduce Anxiety: It’s normal to feel guilty and anxious as a parent. Consider talking to someone about your feelings or utilizing relaxation techniques to help manage your anxiety.
- Ongoing Care: Ensure you remain regular with your valacyclovir doses to help manage your cold sore outbreaks effectively.
If any concerning symptoms arise in your child or if your anxiety intensifies, it could be helpful to reach out for professional support. It's great that you are so attentive to your child's health and wellbeing.

Persistent Headache Mystery
I’m 38 years old, standing at 6 feet tall and weighing 280 pounds. My health profile includes well-managed high cholesterol and major depressive disorder, both of which I am addressing with Vilazodone (40 mg daily) and Rosuvastatin (40 mg daily). Please bear with me as I share a comprehensive account of my health challenges. Over the past five years, I have undergone regular blood tests, which have produced unremarkable findings, highlighting issues like low levels of HDL cholesterol and slightly decreased testosterone (approximately 300). For over five years, I have grappled with unrelenting headaches, which initially developed gradually without any identifiable trigger. The pain level tends to hover around a 3, occasionally escalating to a 6, but never falling below a 2. These headaches are often accompanied by dizziness, a sensation of lightheadedness, cognitive fog, challenges with word retrieval and concentration, along with faint tinnitus. Fortunately, I do not experience heightened sensitivity to loud noises, bright lights, or strong smells. Lying down does offer slight relief, but only minimally. During this period, I've also experienced sporadic vertigo episodes, the duration of which ranges from a few seconds to a couple of days, with three notable occurrences over the last five years. Coincidentally, the onset of my headaches coincided with a pinched nerve in my neck, likely caused by sleeping awkwardly. Physical therapy alleviated the related tingling in my arm. I consulted a neurologist regarding the pinched nerve, who ordered MRIs of my brain and spine. The findings were largely inconclusive, aside from a mildly herniated disc and the pinched nerve. Following this, a different neurologist experimented with various medications to alleviate the headaches, including topiramate, NSAIDs, sumatriptan, CGRP treatments, and Botox—none of which provided any significant relief. The neurologist suggested that my symptoms might be linked to the dual antidepressants I was on at the time (Effexor and Wellbutrin). After tapering off these medications under psychiatric supervision, I did not notice any change after six months, leading me to resume a newer antidepressant due to a considerable deterioration in my depression. A cardiologist was then consulted to rule out conditions like POTS, with normal results from an ultrasound, but a stress test indicated vascular syncope while testing negative for POTS. At this juncture, my psychiatrist speculated that my symptoms could be tied to anxiety. I joined an outpatient support group, where I realized that although I relate to some anxiety symptoms, mine are relatively mild. As a next step, the psychiatrist attempted to enhance my focus with Adderall, which interestingly was the most effective medication for alleviating my symptoms. However, the side effects—including insomnia and irritability—were challenging to manage. Eventually, I secured a referral to a large academic medical center where I consulted with five different neurologists specializing in various aspects of neurology. From there, I was directed to a headache clinic that recommended I cut back on my caffeine intake from three cups daily to two or possibly less, but again, there was no improvement. The headache clinic suggested conducting a sleep study, which revealed mild sleep apnea. I was prescribed a CPAP machine, which I diligently used for over a year, yet this still did not result in any symptom relief. Further, I was referred to a specialist investigating spontaneous CSF leaks. After preliminary home assessments, this physician recommended we explore more invasive imaging through a CT myelogram with contrast and suggested potential treatment involving an epidural blood patch. Despite negative imaging results, the physician mentioned the possibility of a CSF leak not visible in the scans, referencing a few areas that were concerning. Consequently, I underwent four separate blood patch procedures to attempt to seal those questionable regions. While I did experience some temporary improvement following recovery—which required lying flat—these benefits were fleeting and did not last long-term. Additionally, I was referred to an Otolaryngology specialist for vestibular function tests that demonstrated minor deficiencies. Following this, I undertook about six months of vestibular rehabilitation, but it provided little to no symptom improvement, and conditions like BPPV and vestibular migraines were dismissed as possibilities. I may be overlooking other tests or treatments from this extensive journey. After a lengthy period of treatment and numerous appointments that left me feeling drained and directionless, I took a six-month hiatus. Now I feel ready to seek further help and wish to explore ways to enhance my quality of life despite my ongoing symptoms (currently practicing cognitive behavioral therapy) or to seek genuine answers to improve my condition. My primary inquiry is: what should my next steps be? Should I return to the headache clinic at the academic center, consult with a neurologist again, or look for alternate resources?
Understanding My Random Hives and Rashes
Hello everyone, I’m reaching out for some insight. I’m a 20-year-old who generally enjoys good health, takes no medications, and has no known allergies. For the past two days, I've been experiencing sudden outbreaks of red, itchy spots on my skin. I visited urgent care yesterday for this issue, but when I arrived, the intense itching and swollen fingers had subsided, and there were no visible signs, so they diagnosed it as nothing serious. However, that night, I noticed red marks developing on my knees and elbows, and this morning, hives appeared on the backs of my legs. I still managed to go to work, and remarkably, the hives vanished by the time I was home. Yet, just a few hours later, they returned, covering my arms and legs once again, and the itchiness has intensified. Aside from this, I feel generally fine, so I don’t think it's urgent. I’m trying to determine the cause behind these irritating rashes; I’ve examined my diet and ruled out any food allergies since I've eaten different meals than usual recently. To eliminate the possibility of bed bugs, I also thoroughly cleaned my bed. I went to the nearest urgent care, but now I'm considering visiting my primary care physician for further evaluation, hoping they might provide more effective assistance. If needed, I can upload photos of the rashes on my profile for a better look. Thank you in advance for your help!
Strange Line on My Foot: Should I Be Worried About a Blood Clot?
Subject: Seeking advice about a new symptom. I’m a 34-year-old female currently taking several medications, including Wellbutrin, lithium, vitamin D, and a multivitamin. Recently, I started Metoprolol in April to manage my blood pressure. Prior to Metoprolol, I was on Losartan for a few months, but it didn’t work well with my psychiatric medications. It caused me heart palpitations and a racing heartbeat, which led me to visit urgent care one night because I feared I was experiencing a heart attack. However, an EKG revealed that everything was normal. Although my situation has improved since switching to Metoprolol, I continue to experience occasional heart palpitations, which contributes to my health anxiety. Now, moving to the current issue: I observed a red line appearing on the arch of my foot yesterday. This isn’t due to any shoe irritation. Today, I noticed that while the line seems less defined and a bit broader, it has also lengthened, extending towards the bottom of my foot. There's a mild ache that feels similar to muscle soreness, but there is no itchiness or warmth. I am hesitant to visit urgent care only to hear that my anxiety is the culprit again, yet I cannot dismiss my concerns. Any advice or insight regarding this situation would be greatly appreciated. Thank you!
Experiencing Stroke Symptoms?
At 37, I lead an active life with good health, devoid of high blood pressure or cholesterol concerns, rarely indulge in alcohol, and do not smoke. In early June, I received a diagnosis of an internal carotid artery dissection, which led to the development of Horner’s syndrome characterized by a drooping eye and changes in my pupil, also affecting my sense of taste. Following this diagnosis, I began treatment with blood thinners. Initially, I experienced fatigue, occasional numbness, and headaches, but over a three-week period, I started feeling significantly better and completed my course of Plavix, returning largely to my usual self. However, the day after my treatment ended, I noticed some troubling signs: my left hand became awkward, and my foot felt weak. It wasn’t anything alarming, but while visiting the farmers' market, I suddenly felt overwhelmed and began to cry unexpectedly. This prompted me to visit the emergency room, where brain scans, including CT and MRI, appeared normal. Nevertheless, due to my left-hand weakness, I was admitted for further observation. The results from my earlier hospitalization indicated 50% stenosis in my arteries, while the recent evaluation showed an increase to 70% stenosis. In the following two days, my condition deteriorated, manifesting in symptoms such as slurred speech, a slow and monotone voice, tremors in my head, a deviated tongue, mouth drooping, and issues with balance and coordination. These signs began to improve after receiving heparin treatment, but I still experience ongoing symptoms, particularly when fatigue sets in. Whenever I sit at the computer, my head continues to bob, I stutter, and my speech slows down, especially when feeling emotional or tired. Previously, my family joked about my stoic demeanor, but now I find myself crying frequently. **My inquiry:** Could it be that the MRI was performed too early to detect the underlying issues?
Identifying the Cause: Athlete's Foot or Allergic Reaction?
Age: 35, Male Ethnicity: Asian Residence: Bay Area Weight: 125 lbs For the past month, I've been experiencing an issue. Initially, I noticed tiny red spots that were quite itchy. I tried using a topical cream over several weeks, but instead of improving, the lesions expanded and appeared even more unusual. The treatment didn’t seem effective. Could this be a case of hives, as I suffer from them annually, or is it a fungal infection?
