Continuous Coughing for Several Months
As a 30-year-old man with a mild history of asthma, I've been dealing with a persistent cough for the past three months that intensifies after meals. Initially, I suspected it might be due to acid reflux, so I consistently took Pepcid and Tums for a fortnight. I also made sure to remain upright for an hour post-meal, elevate my sleeping position, and avoid eating late at night, yet these changes brought little relief. I've considered that it could be post-nasal drip from seasonal allergies and have tried several allergy treatments. Additionally, I wondered if a food allergy might be responsible, so I've been experimenting with eliminating different food items from my diet. Despite these efforts, I maintain good physical health, largely avoid fast food, and sustain a healthy BMI and regular exercise routine. I visited my doctor who prescribed Symbicort, believing that my existing inhaler wasn't sufficient, as I found myself using it eight times daily without improvement. While the Symbicort does alleviate my coughing after dinner somewhat, the next day, I typically revert to coughing again post-meal. Occasionally, I experience similar coughing spells after breakfast, but never after lunch. There's a sensation of irritation right behind my suprasternal notch that triggers the persistent urge to cough or clear my throat. I can spend hours dealing with an unshakeable itch, but occasionally, a good cough seems to relieve the discomfort momentarily. I have no difficulties with swallowing, and food or liquids never feel as though they're lodged in my throat. There’s no wheezing, and my cough doesn’t produce anything. At times, my throat can feel rough, possibly due to the constant irritation. I would greatly appreciate any insights into what this condition might indicate, as I feel like I'm out of options. Is there a risk of something more serious, perhaps like cancer or an unusual esophageal condition? I've scheduled a follow-up appointment with another doctor; however, navigating the Canadian healthcare system can be quite slow. Thank you for taking the time to read this.

It sounds like you've been experiencing a persistent and frustrating cough that has been resistant to various treatments. Given your background with asthma and the details you've shared, it's understandable to feel concerned about the cause of your symptoms. Let’s clarify some important points and outline next steps.
Key Points:
- Persistent Cough: Coughing for three months, particularly after meals, can stem from several factors including acid reflux, post-nasal drip, or irritation caused by asthma or allergies.
- Current Treatments: You've tried several strategies (elevation, over-the-counter medications, and an asthma inhaler) with limited success.
- Symptom Appreciation: The itchiness behind the sternum and the sensation of irritation suggest ongoing irritation or inflammation that needs addressing.
Explanation:
Your cough, especially since it worsens after meals, is often associated with gastroesophageal reflux disease (GERD) or post-nasal drip from allergies. Since you are already both treating for these and using Symbicort, it may not just be one condition but a combination contributing to your symptoms.
The lack of wheezing, no difficulty swallowing, and the absence of productive coughing are good signs; they lower the risk of immediate serious conditions like esophageal cancer. However, persistent or worsening symptoms should always be evaluated further.
Prioritized Next Steps:
- Re-evaluate Dietary Habits: Keep a food diary to track any correlation between specific meals or ingredients and your symptoms. Pay attention to spicy foods, caffeine, chocolate, and acidic foods, which can exacerbate acid reflux.
- Consider a Trial of Antihistamines: If you suspect allergies or post-nasal drip, using a non-drowsy antihistamine (like cetirizine or loratadine) daily for a few weeks may help reduce nasal drainage, thus potentially relieving your cough.
- Use Humidification: Consider using a humidifier at home, especially if you live in a dry climate. This can help soothe throat irritation.
- Cough Management: For immediate relief, honey in warm water may help soothe irritation (in moderation and only if you're not allergic).
- Follow-Up Appointment: Continue with your scheduled follow-up. If waiting is an issue, express your ongoing symptoms and concerns, which might escalate the need for faster management options. You might discuss additional diagnostic options like a chest X-ray, referral to an allergist, or a gastroenterologist to rule out other underlying issues.
While it’s encouraging that you maintain good physical health, addressing your specific symptoms and their triggers is vital. I hope this gives you some direction on how to proceed. Please keep me updated on your progress or if you have further questions!

Understanding Elevated AST Levels When Other Liver Functions Are Normal
Profile: 44-year-old male, height 6'1", weight 188 lbs, Caucasian, non-smoker, occasional alcohol consumer, no prescribed medications, uses some dietary supplements including a multivitamin, green tea extract, pomegranate extract, and beetroot extract. During a recent check-up, most results were satisfactory; however, a single liver enzyme—AST—was reported slightly above the established reference range. While bilirubin and ALT levels remained within normal limits, this raised a few questions. Additionally, the day prior to the tests, I completed an intense run and consumed a glass of red wine. Over the past couple of months, I also engaged in intermittent fasting for weight loss, during which my weight decreased from 196 to 188 pounds. My BMI stands at the threshold of 25, reflecting that I maintain a relatively active lifestyle. For context, my liver enzyme levels had been normal for the prior two years, and I typically drink alcohol 1-2 times weekly, mostly red wine. All other components of my metabolic panel and complete blood count were within acceptable ranges. Given that both bilirubin and ALT levels are normal, how serious should I consider the elevated AST reading? Could this elevation be linked to my recent running and fasting regimen, or should I be vigilant for other potential health concerns?
Delayed Menstruation
During some intimate interactions, I (26, male) was wearing boxers while she (26, female) was fully unclothed. We engaged in actions that resemble sexual activity, including rubbing and pressing against her vaginal area. Although there was no ejaculation, there was some precum involved. Initially, I didn't worry much as I had come across information suggesting that such activities are generally safe when clothing is involved. However, considering that she is currently in her fertile period, I now feel concerned because her menstrual cycle is two days overdue; she typically has a regular cycle. Additionally, she usually experiences pronounced PMS symptoms, yet this time she hasn’t noticed any signs despite her period being delayed. I'm making an effort to remain calm and avoid alarming her, but I'm increasingly anxious and fear that something might be amiss.
Duration of Hives: What to Expect
Recently, my teenager accidentally sprayed body mist from Bath & Body Works on my 2-year-old, who has no prior health issues. Instantly, she developed hives across her skin and face. We contacted a nursing hotline for advice and have since bathed her in lukewarm water several times, administered Benadryl, and used hydrocortisone cream for relief. Additionally, I applied some previously stored breast milk, which seemed to improve her condition a little before bedtime. However, upon waking up, the hives persisted in various spots on her body. Despite taking Benadryl and using cream, she has been scratching so much that it's causing her to bleed. I had hoped that washing off the irritant would lead to a quick clearing of the rash. How long can I expect the hives to last after eliminating the allergen?
Managing Prolonged Breakthrough Bleeding: Seeking Solutions
A 35-year-old African American woman from Georgia is grappling with ongoing breakthrough bleeding. She has a medical history that includes polycystic ovary syndrome (PCOS) and endometriosis, alongside complex post-traumatic stress disorder (c-PTSD), attention-deficit/hyperactivity disorder (ADHD), and major depressive disorder (MDD). Currently, she is using combination hormonal contraceptives and has been on Lamictal for approximately seven years. Her dosage was adjusted from 150mg to 200mg last year. Recently, she faced unexpected challenges with her birth control method. Initially, she experienced no issues with continuous use, but midway through the three-month cycle, she began having breakthrough bleeding. As a result, a new combination birth control was prescribed, which includes placebo pills at the end of the cycle—she opted to skip these. Initially, symptoms seemed to improve, but during the third week of the second pack, the breakthrough bleeding re-emerged. Now, as she begins the third pack, she finds herself still bleeding, with an increased flow accompanied by fresh blood, clots, and additional endometriosis pain. The possibility that the Lamictal interaction with her birth control might be contributing to her troubles occurred to her, especially since these issues only arose after increasing her dose. Apart from the dosage adjustment, aging is another factor she contemplates in her journey. She recognizes it’s crucial to schedule an appointment promptly but feels uncertain about the next steps to halt the bleeding. Should she consult her gynecologist first? Is there medication available that could help address her current bleeding episode while she awaits a new psychiatrist, having recently switched to Kaiser and needing to find new healthcare providers? Alternatively, should she discontinue her birth control and try to endure the breakthrough bleeding that has persisted for over two weeks? She finds herself exasperated, emotional, and eager for a resolution.
Seeking Affordable Rhinoplasty Options
Greetings, everyone. Today, I find myself in a rather unique situation compared to the typical discussions here, and I genuinely need assistance. I’m a young woman in my early twenties residing in the UK, struggling deeply with the need for rhinoplasty. Frequently, I face difficulties with my breathing due to a deviated septum, and the overall shape of my nose severely impacts my self-esteem and mental well-being. This has been an ongoing challenge for as long as I can remember, and I am reaching a breaking point. While I have explored the waiting list for the NHS, the timeline is simply too long for me to endure, and unfortunately, they do not offer a nose reshaping procedure either. As a student, my budget does not allow for private surgery options. I considered traveling to Turkey for the procedure, but even then, the cost of around £3,000 is beyond my means right now. I cannot convey how disheartened I feel having to share my situation here and seek help in this manner, as I’m typically someone who avoids asking for assistance. If anyone knows of an affordable plastic surgeon or perhaps one who could consider pro bono cases, I would greatly appreciate your advice. Thank you for taking the time to read my message, and may you be blessed.
