Concerns About a Urinalysis Result and Antibiotic Prescription
As a 54-year-old woman, I recently visited my doctor for a routine lab test, feeling perfectly healthy. While preparing to provide a urine sample, I realized that I was not only short on urine but also urgently needed to use the bathroom. In an attempt to fill the cup as best as I could while holding back the urge to poop, I managed to produce a small amount of urine. I noticed that I was quite close to an accident but ultimately succeeded in filling the cup before rushing to the toilet to relieve myself. After the sample collection, I didn’t observe any fecal matter on the cup or anything concerning. Fast forward four days, and I received a call informing me that antibiotics had been prescribed for a urinary tract infection (UTI). Although I am no stranger to UTIs from two decades ago, I am currently asymptomatic. When I questioned the medical staff about the necessity of taking antibiotics given my lack of symptoms, they firmly asserted that it was essential. I felt hesitant to discuss the potential contamination of my sample with feces, especially since it was Friday afternoon, right before the weekend. Now, I'm left contemplating whether I should proceed with the antibiotics or if this diagnosis might be a result of the sample’s possible contamination.

It's understandable to feel uncertain about starting antibiotics, especially if you're asymptomatic following your urinalysis. Let's break down the situation regarding your test results and the suggestion to take antibiotics for a urinary tract infection (UTI).
Main Points:
- Understanding the Urinalysis Results: Sometimes, urine samples can be affected by contamination, particularly if you were rushing and felt the need to use the bathroom. If there was potential contamination, it could influence the test results.
- Asymptomatic UTIs: Many medical professionals recommend treatment for UTIs even if you don't have symptoms, especially if your urinalysis showed specific markers indicating an infection.
- Concerns About Antibiotic Use: Taking antibiotics without evident symptoms can raise concerns about antibiotic resistance and side effects.
Explanation:
When your doctor diagnosed a UTI based on the urinalysis, they likely found bacteria or other indicators of infection, which often leads them to prescribe antibiotics for treatment, especially if there are high risks associated with untreated infections. However, the context of your sample collection—specifically, the urgency you felt—could mean that the results are not entirely reliable.
Next Steps:
- Reassessment of Symptoms: Gauge any changes over the next couple of days. If you remain completely symptom-free (no burning sensation, increased frequency of urination, or pain), note that.
- Holding Off on Antibiotics: Consider postponing taking the antibiotics for now to see if you remain asymptomatic, discussing with your healthcare provider about your hesitance regarding the contamination of the urine sample.
- Requesting a Follow-Up Test: If you're comfortable, request a repeat urinalysis to confirm the infection, especially if you have doubts about the initial results. This can help clarify if treatment is necessary.
- Consulting Again on Monday: If you're still unsure, or if any symptoms do develop, you can call your doctor or the medical office on Monday for further advice, addressing your concerns about the sample's potential contamination.
It's important to prioritize your health, and seeking clarification or a second opinion is always a valid approach. You're actively participating in your healthcare, which is vital for making informed decisions. Let me know if you need further clarification!

Seeking Insights on Long Covid Respiratory Issues
Greetings, everyone. I’m reaching out for assistance because I have been enduring a persistent respiratory symptom for the past five years, and I would greatly appreciate any advice or insights. Here's a brief overview of my situation: **Personal Medical Background:** - Female, 21 years old, history of asthma since childhood, which became less severe over the years until the onset of the COVID-19 pandemic. I stopped relying on a rescue inhaler after turning nine. - Experienced a severe MRSA infection in the nasal area in 2020, which led to a cyst and granuloma that necessitated surgical intervention. I recuperated without complications. - No family history of chronic obstructive pulmonary disease (COPD) or any hereditary respiratory conditions. **Timeline of Illness:** - I contracted COVID-19 in June 2021, exhibiting only mild cold-like symptoms during the illness, and was otherwise in good health. - Around two days post-infection, I encountered this persistent respiratory issue for the first time. **Current Symptoms:** Since recovering from any respiratory illness, including COVID, I have consistently experienced the following symptoms in the order presented: 1. Chest tightness and breathlessness 2. Post-nasal drip, escalating from mild to severe 3. Presence of both dry and productive coughs 4. Occasional sore throat, often resulting from persistent coughing 5. Expectoration of mucus that ranges from white to light yellow 6. Wheezing and asthmatic tendencies. I have had to purchase an inhaler again for these symptoms, despite having no need for one since I was ten. 7. Lightheadedness 8. If untreated, these symptoms can ultimately lead to pneumonia. **Infection Details:** - To my knowledge, all infections have been bacterial and have responded well to varied antibiotic treatments (including amoxicillin and Z-Pak). - Amoxicillin has proven to be the most effective, as it alleviates symptoms the quickest (and I always ensure to complete the prescribed antibiotic course). - Following treatment, all respiratory symptoms vanish completely until I experience another respiratory complication that rekindles the cycle. - There has been no increase in the frequency of such infections; I still contract them with the same regularity as before COVID, approximately once annually during the flu season. - Symptoms will not resolve without treatment; I have spent up to six months untreated before the pneumonia symptoms became overwhelming. **Latest Infection:** My most recent respiratory challenge began about ten days ago and has presented itself differently than before: - This time, the initial onset wasn’t linked to a respiratory illness; the symptoms appeared following an allergic reaction after cleaning animal enclosures and developed into familiar symptoms by the next day. - The progression of this latest infection has been alarmingly swift, showcasing more significant breathlessness within a week. - I have not yet explored potential antibiotic resistance, but I have an appointment with my doctor soon. Originally, I speculated that I might have a colony of MRSA residing in the back of my throat that becomes active whenever my immunity is low. However, this theory doesn’t align with the effectiveness of standard antibiotics like amoxicillin. I have undergone testing for strep throat during symptomatic episodes, which yielded negative results. I consulted with a pulmonologist, who seemed to echo my suspicions, attributing it to a secondary bacterial infection. I am keen to explore if I am overlooking any other factors while examining my situation holistically. Thank you for any insights or guidance you may have!
Respiratory Concerns After Cold in Hong Kong
A couple of days ago, I experienced flu-like symptoms, but my condition has improved significantly. Now, I only have a sore throat. However, while trying to clear mucus from my throat, I unexpectedly coughed up two unusual, flesh-like substances. I am seeking advice on what this could mean and if I should be concerned.
Concerns About Blood Pressure and Heart Rate: Seeking Advice
I am a 25-year-old female, and as of my last weigh-in on Friday, I am 122.8 lbs. My current medications include: - Lamotrigine/Lamictal at a dosage of 150mg daily - Quetiapine Fumarate/Seroquel at 50mg, administered twice daily (one dose around 8:30 PM and another right before sleep, totaling 100mg each day). These medications are aimed at addressing mental health challenges, specifically bipolar disorder type II, with some potential indications of borderline personality disorder and anxiety. The quetiapine also assists with sleep. Aside from my mental health, I have been diagnosed with patellofemoral malalignment syndrome following an ankle fracture. Fortunately, I have not experienced any major injuries aside from that and a few minor stitches. There have been no surgeries or additional health issues to report. I intend to visit a healthcare provider once my insurance becomes active, but in the meantime, I seek some guidance regarding my symptoms to determine if they warrant serious concern. Lately, I've found myself experiencing dizziness, particularly when I stand up quickly, and this has become more frequent and intense. At times, I notice spots in my vision when I rise. Just this past Thursday, I experienced a particularly severe episode, feeling lightheaded and dizzy for the rest of the day. Some friends, whose acquaintances have Postural Orthostatic Tachycardia Syndrome (POTS), recommended that I monitor my blood pressure and heart rate, so I purchased an Omron blood pressure monitor, noted for its clinical reliability. When seated, my blood pressure usually hovers around 100/70 in the morning, with my heart rate in the high 90s to low 100s. By evening, my blood pressure typically drops to approximately 90/65, while my heart rate decreases to the 80s. According to my Samsung Watch5 Pro, my resting heart rate generally falls between 60 and 80 beats per minute. Curious about my symptoms, I decided to conduct the NASA lean test at home a few times. On each occasion, my blood pressure elevated into the hypertension range, reaching a peak systolic reading of 130/83 and a diastolic high of 121/86. Every time I completed the test, I experienced significant dizziness and lightheadedness upon standing, along with a pronounced sensation of my heart racing. There was a noticeable increase in my heart rate, typically fluctuating by 15 to 20 beats per minute from lying down to standing. By the seven-minute mark, I usually felt nauseous, but I’m relieved to say I have not fainted during any tests. Could this be classified as normal bodily reactions, or are these signals—dizziness, lightheadedness, visual disturbances, and nausea—indicative of an underlying issue? Should I consider this enough of a concern to seek urgent care, or is it something I can simply mention in my upcoming appointment with my general practitioner? Thank you for any insights you can provide!
Respiratory Concerns
Hi there, I’m an 18-year-old male and I recently fell ill quite suddenly. I was at work when I started experiencing a mild cough, which I initially brushed off as nothing serious. However, just two hours later, I found myself vomiting and struggling to breathe. At present, I’m dealing with a slightly congested nose, swollen tonsils, a mild cough, chills, a warm forehead, and primarily, issues with my breathing. Inhaling feels like my lungs are barely functioning, while exhaling produces an unusual sound, making it challenging to expel air from my lungs. I suspect it might just be a common illness, but I've never experienced such a significant lack of breath before. I’m wondering if I might need an inhaler. Also, I do smoke and vape, but it’s been less than a year. Should I head to the emergency room, or is it better to wait it out?
