Determining Between Cold Sores and Angular Cheilitis
(39F) In the past, I've experienced cold sores, but this time felt a familiar sensation on Thursday evening. By Friday evening, I had a prescription for cold sore treatment. Today, however, I find a painful spot in my nose accompanied by dry, flaky skin around my lips and nostrils, in addition to the existing sores. Did the medication have an effect last night after my first dose, or is a longer period required for it to take effect? Could this be an indication of something different, or perhaps a severe reaction stemming from my recent use of the CPAP machine, which I am still struggling to acclimate to? I currently utilize a Resmed F20 full face mask.

It sounds like you're experiencing some significant discomfort with potential cold sores and new symptoms around your nose and lips. Let's break this down:
Main Points
- You may be dealing with cold sores, but the additional symptoms of dry, flaky skin and pain suggest that you could also have angular cheilitis or irritation from your CPAP mask.
- Immediate actions include maintaining moisture around your lips, ensuring proper hygiene, and observing the healing process of your cold sores.
Explanation
Cold sores are typically caused by the herpes simplex virus and can manifest as blisters or sores on or around the lips. Treatment usually begins to work within a day or two, but if you're seeing new symptoms like flaky skin or pain in the nostrils, it may indicate another issue, such as angular cheilitis. This condition can result from dryness, irritation, or fungal infection, often exacerbated by factors like a CPAP mask if not fitted properly or if it causes moisture accumulation.
Next Steps
- Moisturize: Apply a gentle lip balm or emollient on your lips and the skin around your nose to keep it hydrated.
- Analyze CPAP Use: Check your CPAP mask fit to ensure it’s not too tight, which can cause skin irritation. Make sure to clean it regularly to prevent potential infections.
- Monitor Symptoms: Keep an eye on the new symptoms. If the painful spot or dryness persists or worsens, consider adjustments to your skincare or a change in how you use your CPAP.
- Follow Treatment: Continue taking your cold sore medication as prescribed, and give it some time to work. Monitor for any change in your cold sore symptoms.
- Avoid Irritants: Stay away from harsh soaps or skin products around the affected areas to reduce irritation.
If symptoms do not improve in the next few days or if they worsen, consider re-evaluating your treatment plan for your cold sores or the irritation you’re experiencing. Take note of how you feel and seek support if needed. Remember, it’s important to take care of both your physical and emotional well-being as you navigate these symptoms.

Managing Early Appendicitis: Antibiotics vs. Surgery
I’m a 21-year-old who recently had a CT scan revealing mild inflammation in my appendix and lymph nodes. My doctor informed me that surgery might not be necessary if the antibiotics effectively alleviate my discomfort by tomorrow.

Has anyone opted for antibiotics rather than surgical intervention? What was your experience like?
Concerns Over My Partner's Persistent Pain and Resistance to Seek Medical Help
I’m facing a worrying situation with my partner, a 40-year-old man who stands 6 feet 1 inch tall and weighs approximately 19 stone. Here's a brief overview of his medical background: Twenty years ago, he experienced two instances of deep vein thrombosis (DVT) in his left shoulder. Following the second incident, doctors discovered an abnormal growth of a rib that was pressing against a vein, which was the cause of those DVTs. More recently, he dealt with a blood clot in his calf last year. Fortunately, that was successfully treated, and he returned to his normal health. Although he was advised to continue taking apixaban for the long term, he has, unfortunately, chosen not to follow through with this guidance. He also has a history of elevated blood pressure. For the past couple of days, he has been experiencing two concerning symptoms that emerged simultaneously: a persistent cough with no accompanying cold or flu signs, and a severe pain located on the right side of his torso. He describes this discomfort as being mostly in his stomach yet extending slightly to his back. I would pinpoint the troubled area as the lower part of his ribs along the side of his body. It's unusual for him to express discomfort or complain about his health, so his recent grievances signal to me that the pain is likely quite significant. Despite my repeated suggestions for him to visit a doctor, he insists that he may have simply pulled a muscle. To manage the pain, he's been applying an ibuprofen cream (voltarol) and taking naproxen, but neither seems to provide relief. What might be the underlying issue here? I hope that some medical professionals who see this post can offer their insights, which might persuade him to consider making a doctor’s appointment. I’m open to providing any additional information you might require for a more informed perspective. Thank you for your help!
Struggling with Bleeding and Pain Since Christmas
I'm a 27-year-old woman from the UK, and I've reached a point of exasperation. I'm reaching out because I hope someone can provide insight or guidance on what I should discuss with my doctors. Please excuse any grammar or spelling errors as I have dyslexia. I've been diagnosed with endometriosis and underwent surgery in 2022 for confirmation of that diagnosis. On December 15th, I had my birth control implant removed after nearly two years. During that period, I experienced severe menstrual cramps and PMS. My GP started me on Drospirenone 3mg and Estetrol 14.2mg COCP in October to alleviate these symptoms and suppress my periods, which provided some relief. Prior to this situation, I occasionally dealt with flare-ups that typically lasted a few days or up to a week. To help manage the discomfort, I have been prescribed Duloxetine at a dosage of 90mg. I had an ultrasound earlier this summer, and the results came back normal. Currently, I am awaiting an MRI. Last year, my smear test results were also clear. After the removal of my implant in December, I began bleeding on Christmas Eve. Initially, I could manage with just a panty liner, but over the next few weeks, the bleeding intensified, requiring the use of pads due to increased blood flow and blood clots. Given my history with endometriosis, pain isn't unfamiliar to me; my average pain level is around a 4, but it has recently escalated to 7 or 8. In the past couple of weeks, the discomfort has worsened. My job demands physical activity, and bending over now causes pain in my back and legs. Additionally, I experience discomfort when my bladder fills, and urination is painful, although it doesn't feel like a urinary tract infection. I've also been waking up at night to use the restroom. My doctor performed a urine dip test that showed no signs of infection, though there was blood in my urine, which he indicated was to be expected. Recently, my GP prescribed Tranexamic acid 500mg and Mefenamic acid 500mg, which helped with the blood clots, but I'm still experiencing bleeding and significant pain. I've been diligent about taking my medication, treating it like a strict regimen. I returned to the GP, who referred me for another ultrasound and advised me to go to A&E if the pain worsens. I've been resting as much as possible while still trying to maintain some level of activity, but it hasn't provided much relief. Any assistance or advice would be immensely appreciated! Thank you!
Experiencing Unusual Sensitivity to Paracetamol
Hello, Reddit community! I'm a newcomer here, so please bear with me as I navigate this platform as well as the rules. I appreciate your understanding regarding my writing skills. I find myself in a situation that lacks sufficient information online, and I'm reaching out for insights from others. Currently, I have reasons to believe that I might be experiencing a unique sensitivity to paracetamol, and I’d like to share my timeline regarding this matter. Throughout my life, I generally had no issues with paracetamol. I used various brands multiple times and felt fine. However, starting in the fourth grade, I began to experience difficulties with it. My initial problems were respiratory-related, but soon they also affected my gastrointestinal system. I haven't had any formal testing yet, but I can safely use other pain relievers like NSAIDs without any adverse effects. Initially, I tolerated paracetamol relatively well; my early symptoms seemed like common side effects. Unfortunately, it escalated to severe reactions, including vomiting, tightening of the throat, blood in my mucus, and shortness of breath. In my confusion, I thought limiting my dosage could help, which it did temporarily, but eventually even the reduced amounts failed to be effective. I experimented with syrup formulations that contain less paracetamol or where it isn't the primary ingredient, and found those to be more manageable. Recently, however, even those have become problematic, making it necessary for me to seek alternatives to paracetamol, as it has become increasingly intolerable. Through my research, I discovered that such reactions often stem from cross-sensitivity to other medications or from preexisting respiratory conditions. I lack a history of asthma or other respiratory issues, so I’m inclined to dismiss that possibility, although I remain uncertain. Moreover, I have no known allergies, which adds to my confusion since my reactions only occur with this one particular medication while all others seem fine. It is difficult for me to process this change, especially since I used to have no issues with paracetamol. It is widely available and generally considered safe, so I struggle to understand the source of my suffering. Many people insist that these reactions are normal side effects, leading me to question whether I am overreacting. The immediacy of my reactions intensifies my concern; I don’t even need to swallow the medication completely before I notice my throat constricting, increased mucus production, and shortly thereafter, some blood in my mucus along with persistent coughing. This pattern has become consistent, whereas it used to depend on the dosage. Now, regardless of how much I take, the same symptoms occur. I’ve tried to dismiss it, not wanting to worry my parents or seek medical attention for a dosage safety test, fearing I’ve already pushed my body too much. However, I am considering discussing my concerns with my mother since she is increasingly worried about my use of this medication. I’m not seeking a diagnosis or medical advice—I understand I should probably consult a professional. I’m just interested in knowing if anyone else has faced similar experiences, as the confusion grows. What I once assumed were normal side effects now seem to signify something more concerning.
