Understanding Persistent Cold Sores: Should You Consult Again?

2/13/2026, 7:00:32 PMMale25-34

I've been living with various health conditions including narcolepsy, fibromyalgia, anxiety, depression, PMDD, and OCPD. My current medication includes Cymbalta, Xywav for narcolepsy, and Junel for birth control, along with Zyrtec and Flonase to manage my allergies. Cold sores have been a recurring issue for me, typically cropping up once a year. Generally, a single cluster of blisters emerges and resolves within a week to ten days. In the past, Valtrex has been remarkably effective for me. Recently, however, I experienced a different pattern. This Monday, a cold sore appeared, and following a prompt virtual consultation, I received a prescription for Valtrex. Initially, I noticed an improvement in the original sore, but just two days later, I developed another sore on my lip, and then yet another formed between my lip and nose the following day. I'm aware that cold sores can result from various triggers, including stress, which has been particularly prominent in my life lately. Nevertheless, the extent of this outbreak feels unprecedented for me. I am curious if this is typical behavior for cold sores, especially after using Valtrex, or should I schedule another virtual appointment to discuss the possibility of needing an additional dosage? If necessary, I can provide a photo for reference.

It sounds like you've been experiencing a troubling increase in the frequency and severity of your cold sore outbreaks, especially given your history of managing them with Valtrex. Cold sores, caused by the herpes simplex virus, can indeed exhibit varying patterns, particularly in times of stress, which you've pointed out is a current factor in your life.

Key Points:

  • Cold sores can be triggered by stress and other factors, leading to outbreaks that feel more intense than usual.
  • Valtrex is typically effective in managing outbreaks, but some individuals might require adjustments in treatment during more severe episodes.

Explanation: Cold sores generally manifest as clusters of painful blisters and typically heal within about a week. When you're experiencing what feels like an unprecedented outbreak, particularly with the rapid emergence of multiple sores, it could suggest a heightened sensitivity or a change in your immune response. Stress can weaken your immune system and make your body more susceptible to outbreaks.

Next Steps:

  1. Continue Valtrex: Stick to the prescribed regimen for Valtrex as directed, since it is still the best option to reduce the duration and severity of outbreaks. Follow the dosage guidelines provided by your healthcare provider.

  2. Monitor Symptoms: Keep a close eye on the number of cold sores you develop over the next few days. Note any accompanying symptoms, such as pain or itching, and document how long they last.

  3. Self-Care Strategies:

    • Stress Management: Given your acknowledgment of heightened stress, consider incorporating stress-reduction techniques such as deep breathing, meditation, or gentle exercises such as yoga.
    • Avoid Triggers: Identify and avoid known triggers when possible, including certain foods, prolonged sun exposure, or overwhelming stress.
    • Topical Treatments: Over-the-counter creams containing docosanol can help reduce healing time if applied early.
  4. Consult if Necessary: If the symptoms do not improve or worsen, or if you have additional concerns about your cold sores or other symptoms related to your health conditions, it may be wise to schedule another consultation. You can discuss your current medication regime and the idea of potential dosage adjustments or alternatives.

Your experience sounds challenging, but addressing these outbreaks actively will likely lead to improvement. Prioritize your symptom monitoring and stress management as critical steps. Let me know if you have more questions or need further support!

Surgery Recap: Seeking Recovery Experiences After Tricep Tendon Repair

I underwent surgery yesterday to address a completely torn tricep tendon. About three weeks ago, I experienced a fall while ascending the outdoor stairs at my residence, resulting in the injury. At 37 years old, I maintain a generally healthy and active lifestyle. Unfortunately, the surgery involved reattaching my tricep tendon to the bone, and the nerve block has worn off, leading to significant pain since I woke up this morning. I feel quite uneasy about the path to recovery and am eager to hear from anyone who has faced a similar situation or knows someone who has. I'm someone who enjoys staying active—lifting weights, running, playing golf, and practicing yoga. My children are also involved in various sports, and I love playing basketball and throwing a ball around with them. I’m curious to know how long it took for others to resume their pre-injury activities and regain their normal routine. Any insights or experiences you could share would be immensely helpful and appreciated.

Chest Bump Becoming Painful: Seeking Advice

I’m a 26-year-old male experiencing some concern regarding a bump that has been situated in the middle of my chest for the past 2-3 years. Initially, it was never a cause for worry, and during a check-up in 2024, my doctor assured me that this bump was simply my Xiphoid Process. However, a shift occurred just a few days ago; the bump began to feel very tender and bruised. For the last three days, I've been managing the discomfort, but it has become exceedingly sensitive to touch, raising my level of concern. The bump is located directly over my sternum at the level of my nipples and seems to have increased slightly in size compared to its original state. Additionally, the skin on either side of this bump has developed a reddish hue, while the center appears paler. I have not experienced any other noticeable symptoms besides localized pain, particularly when I engage in movements that stretch or strain this chest area. I haven’t collided with that part of my body in a way that would lead to this degree of bruising, so I’m unsure about the appropriate next steps. Where should I seek assistance regarding this issue? Any guidance would be greatly appreciated! Thank you!

Dealing with Persistent Boils: Seeking Solutions

I'm a 48-year-old white male, and for years, I have been grappling with a recurring issue that is extremely bothersome. The problem is particularly vexing because the boils crop up in a rather awkward area—right in the buttocks crease. Although I’m not excessively overweight—I weigh 275 pounds, stand at 6 feet 1 inch tall, and maintain a body fat percentage below 30%—I’ve never struggled with acne or any significant skin conditions before now. This is how it unfolds: I might enjoy a period of normalcy for weeks, only to suddenly discover a lump. Initially, it’s just irritating, but before long, it becomes tender and ultimately ruptures, all in just a few days. What’s the nature of the discharge? If I’m fortunate, it’s merely a clear, sticky fluid with a syrup-like texture. Other times, it involves pus or blood. Truthfully, the discomfort isn’t overwhelming, but the aftermath is quite disruptive—once it bursts, I often end up soiled in my underwear, which can seep through my pants. This results in more embarrassment than anything else. I find myself at a loss for solutions. I usually take showers most nights, but let’s be honest, not everyone has the capacity to soak in a bath every single evening! At one point, I even mistook the situation for hemorrhoids and resorted to using specialized wipes multiple times daily, ensuring the area was kept clean. As I’ve mentioned, I suspect these are boils, but could it be something else? Is there an effective way to prevent them from recurring so frequently, irrespective of the season—be it summer, winter, spring, or fall?

Bump on Neck Following Severe Pain

Hello everyone! I’m an 18-year-old male, standing at 5'10", and just slightly under the average weight for my age. A couple of days ago, on Wednesday, I experienced an unimaginable level of pain in my neck when I woke up. Attempting to turn my neck to the right was unbearable, while turning left was somewhat manageable. Due to this intense discomfort, I had to miss work, as even standing or driving was extremely challenging. The next day, I noticed an improvement; I could rotate my neck further to the right. However, while gently massaging the back of my neck, I discovered a small lump, possibly the size of a pea, or even smaller. I didn't think too much about it at first, but upon checking again the following day, it appeared to remain unchanged. After some research, I’ve been reassured that it’s likely nothing serious. When I apply pressure to this bump, it doesn’t feel immovable like a rock; instead, it seems to shift a little, suggesting it isn’t entirely solid or fixed in one position. Although the pain persists, I can now turn my neck almost fully to the right. However, certain angles still induce discomfort, particularly when I inadvertently apply pressure around the lump area. This bump is located at the upper back of my neck, slightly to the right, just beneath my skull. I can’t schedule a doctor’s appointment until Monday, so I wanted to share my experience here in hopes that someone might have insight into this situation. Apologies for the disorganized structure—I'm writing this while at work. Thanks for any help!

Anxiety About Upcoming EGD Procedure

Greetings, I’m a 23-year-old Caucasian male residing in the United States. Throughout my college years, I didn't prioritize nutrition and I led a fairly sedentary lifestyle. I had occasional recreational marijuana use and drank alcohol regularly; however, I have since reduced both habits since last November. Over the last year, I have experienced intermittent mild symptoms of gastroesophageal reflux disease (GERD), including some heartburn and reflux, particularly after consuming spicy dishes. Recently, a surge of health-related anxiety has prompted me to undergo various tests; I have had a colonoscopy, a chest CT scan with IV contrast to check for pulmonary embolism, and several cardiac evaluations, all of which yielded normal results. Apart from a slightly elevated mean platelet volume (MPV) of 8.6 noted a month ago, my blood tests were unremarkable. My GERD symptoms were not a primary concern at that time, and they typically fluctuated without causing significant issues beyond occasional indigestion. Last Saturday, however, I found myself consumed with worry about the possibility of having stomach cancer. Despite my gastroenterologist’s reassurance, an EGD (esophagogastroduodenoscopy) was scheduled to investigate my symptoms further. As my appointment approaches in six days, I am plagued with fear about receiving bad news regarding my health. I have no significant family medical history, and my symptoms include: - Recurrent acidic belching - Discomfort in the upper left abdomen, with some pain in the lower region - Persistent dull chest pain along the left side, occasionally on the right - Frequent belching accompanied by bloating - Decreased appetite, which has emerged recently as my anxiety has intensified - Intermittent upper back pain, likely exacerbated by poor posture I can't shake the terrifying possibility of having stomach or esophageal cancer and the thought of the endoscopy leading to grim news. Although several friends have reassured me that the risk is low, considering my age, lack of severe symptoms, and no family history, I still fear that hoping for a positive outcome will only lead to disappointment. Enduring the next six days feels overwhelming, and I've been attempting to reach out for a sooner appointment. If anyone has advice or suggestions on how to cope with this anxious period, I would greatly appreciate it. I’m wrestling with the fear of hoping for positive results only to have that hope shattered.
