Kidney Discomfort with UTI-like Symptoms
Greetings! I’m a 29-year-old woman who has generally enjoyed good health. My current medications include Benadryl, occasional stool softeners, a vitamin D supplement, and Mounjaro. I do not indulge in smoking or alcohol consumption. For the past couple of months, I've been experiencing intermittent symptoms reminiscent of a urinary tract infection (UTI). Despite undergoing two courses of different antibiotics – macrobid and bactrim – I found that neither treatment was particularly effective, although I did notice a reduction in symptoms. A few weeks later, however, I experienced a significant flare-up; the discomfort in my kidneys was intense enough that I resorted to using a heating pad. The familiar symptoms resurfaced – I faced difficulties with urine retention, a pressing urge to urinate, painful urination, and an overall ache in my pelvic area. Since I work at a family practice, my supervisor promptly ordered a renal and pelvic ultrasound, along with urine cultures for testing. The results returned clear, indicating no growth in the urine culture, which was reassuring. Prior to the ultrasound, I was treated with two doses of rocephin, just in case it was an aggressive UTI. Additionally, renal blood tests were conducted, and thankfully, the outcomes were all normal. However, I did notice that my chloride levels were just one point shy of the high threshold, which gave me some cause for concern. I've recently incorporated D-Mannose and cranberry extract into my routine, alongside increasing my water intake to see if that alleviates the discomfort. I’m puzzled about the underlying cause of my symptoms and wondered if Benadryl could be the culprit. I sometimes take it excessively, and in light of my troubles, I’ve ceased using any allergy medications for the past few days. This entire situation has become quite frustrating, and I fear that my kidneys might be at risk, despite the test results appearing normal. Here are my renal panel results: - Sodium: 140 - Potassium: 4.1 - Chloride: 108 - CO2: 23 - Urea (BUN): 17 - Glucose: 95 - Creatinine: 0.73 - Calcium: 9.1 - Anion Gap: 9 - Phosphorus: 4.2 - Albumin: 3.8 - eGFR: 113.8 Note that I did not fast before these tests. If any nephrologists or individuals with urology expertise could provide insight based on these results, I would greatly appreciate your advice. Thank you in advance for your help!

It's understandable to feel concerned about your symptoms, especially given the persistence of your discomfort and the various treatments you've tried. You seem to be experiencing a complex situation with UTI-like symptoms and kidney discomfort despite clear test results. Here’s a breakdown of your situation, potential considerations, and prioritized next steps:
Summary of Key Points:
- You have intermittent UTI-like symptoms despite negative urine cultures and normal renal blood test results.
- You recently used antibiotics which have provided temporary relief but have not fully resolved your symptoms.
- You are concerned about your kidney health and the possible impact of medications, such as Benadryl.
Explanation:
Your symptoms, including painful urination and discomfort around the kidneys, can be frustrating. Since your urine cultures have returned negative, it’s possible that you might be dealing with an interstitial cystitis (bladder pain syndrome) or other non-infectious conditions rather than a typical urinary tract infection. The fact that your renal tests are normal suggests that your kidney function is stable at this time, which is reassuring.
Regarding Benadryl, while this medication is generally safe, excessive use can lead to side effects such as urinary retention and potentially add to your discomfort. Additionally, D-Mannose and cranberry extracts may help support urinary tract health but are unlikely to resolve underlying issues if present.
Next Steps:
-
Monitor Symptoms: Keep a detailed diary of your symptoms, noting any triggers or patterns. This information can be helpful in identifying any links with your current medications, diet, or activities.
-
Hydration: Continue to stay well-hydrated, as this can help dilute your urine and may ease symptoms. Aim for at least 8-10 glasses of water daily, adjusting based on your activity level and any advice from your healthcare provider.
-
Consider Medication Review: Ceasing Benadryl may be beneficial. If allergy symptoms arise, discuss potential alternatives with a healthcare provider that might not exacerbate your urinary issues.
-
Lifestyle Adjustments: Incorporate pelvic floor exercises to strengthen your pelvic muscles, which may improve urinary function and reduce discomfort.
-
Follow-up: Since you have already undergone tests, consider discussing with your supervisor or general practitioner about additional evaluations, such as an appointment with a urologist or nephrologist for further insights into possible conditions like interstitial cystitis or bladder dysfunction.
-
Be Alert for Changes: If you start noticing any new or worsening symptoms, such as fever, blood in urine, or persistent severe pain, seek medical attention promptly.
By addressing these aspects, you may find better relief from your symptoms. Remember, you are taking proactive steps to understand and improve your health, and that is a strong approach. Please keep me updated on your progress or let me know if you have any further questions.

32-Year-Old Man Experiencing Ongoing Muscle Twitches and Spasms—Should I Be Concerned About CJD or Other Serious Conditions?
Hello everyone, I’m a 32-year-old man standing 6 feet tall and weighing 220 pounds. Since June of last year, I’ve been dealing with sporadic muscle twitches and spasms all over my body. After consulting a neurologist, I underwent both an EMG and a nerve conduction test, and thankfully, the results returned normal. However, these twitches haven’t completely subsided. Recently, I’ve noticed they seem more intense—almost like sudden jolts in my arm or leg. While it doesn’t cause my entire limb to move uncontrollably, it is undeniably uncomfortable and occasionally surprises me. I stumbled upon information regarding myoclonus and now I’m curious if that might be what I’m experiencing. However, most footage I’ve come across illustrates rhythmic or repetitive jerking movements, which doesn’t exactly align with what I’m feeling. Nonetheless, I’ve learned that myoclonus might be associated with more severe neurological disorders such as CJD, which has been causing me considerable anxiety. Is it normal to experience such symptoms at my age, or should I be genuinely worried? I would greatly value your thoughts and any shared experiences you might have. Thank you in advance.
Elevated Progesterone Levels
For some time now, I’ve sensed an imbalance in my hormones. Having just reached the age of 40, I’ve been experiencing various symptoms, including persistent lower abdominal discomfort, hair thinning, breakouts, and significant weight gain, not to mention hypertension, all of which have emerged over the past few years. Recently, I decided to undergo a private blood test to gain insight into my hormonal health. Although the test could not evaluate my estrogen levels—likely due to an insufficient sample size—the analysis revealed my progesterone was recorded at 1.6 nmol/L on the third day of my menstrual cycle. Notably, the only other result that fell outside of the normal range was my cholesterol level. I had anticipated that my progesterone levels would be lower, to be honest. This brings me to question the potential factors leading to this elevation in progesterone.
How to Handle Withdrawal: Seeking Guidance
At 19 years old, I've been grappling with substance use since I was about 15. Life's challenges—including a troubled relationship, an unstable home environment, and ongoing mental health struggles—have driven me to this point. Recently, I’ve realized I want to break free from this cycle. The problem is, the high I once experienced is gone, and I’ve been feeling increasingly unwell. I’ve even had frightening experiences where I’ve choked on my own vomit after losing consciousness, which is alarming. Unfortunately, I can't afford professional treatment or rehabilitation centers, so I plan to face this challenge at home. However, I’m filled with anxiety about the process; I fear making mistakes that could lead to further harm. I’m reaching out for guidance—any tips on how to navigate this situation safely would be immensely appreciated. I'd like to know effective strategies, potential pitfalls to avoid, and any general advice that could aid me during this difficult time.
Understanding Changes in Spleen Size: Should I Worry About Lymphoma?
Hello everyone, I’m a 25-year-old male who has been on quite a journey with my health. I started off at 107 kg back in January and, following a cold, adopted a restrictive diet of just 1000 calories a day. By April, I managed to reduce my weight to 86 kg, and I have maintained a steady weight between 85 and 86 kg since then. Recently, I found myself in the emergency room because of a mild gastritis episode. Thankfully, all my blood tests came back normal, although a differential count for white blood cells wasn’t performed. At the ER, my alkaline phosphatase level was recorded at 138, but this was dismissed by the medical team. During an abdominal ultrasound conducted by a nephrologist, I was informed that everything appeared normal except for my spleen, which measured 16 cm. After conducting further research and diving into information on Reddit regarding health concerns, I grew increasingly anxious about potential cancer. However, a follow-up ultrasound two weeks ago noted a decrease in the spleen's size to approximately 14.25 cm. While I experience itching throughout my body, it's important to mention that I have a known psoriasis condition. The itchy areas tend to be mostly dry rather than the classic patches associated with psoriasis. I don’t suffer from severe fatigue; however, I have been feeling chills periodically at night. Additionally, I've noticed that one of my salivary glands seems slightly swollen compared to the other, although it’s only apparent when I’m active or straining my neck. I have a couple of urgent questions: 1. Is it possible that the initial sonographer could have mismeasured my spleen by almost 2 cm? 2. If the measurements are accurate, does a decrease in spleen size mean that lymphoma is unlikely? Right now, I’m feeling quite overwhelmed because my doctor isn’t available for another year, and I’m left with many uncertainties about my health.
Dealing with a Burst Cyst and Unexplained Symptoms
At 32 years old, I have a tendency to develop what I refer to as cysts, even though medical professionals have been somewhat uncertain about their exact nature during my previous appointments. Recently, on Sunday, I discovered a new one forming near my bikini line. I believe I had a similar issue at that exact location last month; however, it seemed to improve with the use of sitz baths and warm compresses. Unfortunately, this time, I noticed it too late, as it had already grown quite large, turned red, and became tender. Once again, I started applying warm compresses and taking sitz baths. To my surprise, by yesterday afternoon, the cyst had ruptured, and I found that it was draining pus mixed with a bit of blood. I continued my routine of warm compresses. Last night, I suddenly began to feel quite achy and generally unwell. Initially, I assumed these symptoms were linked to the infection, but then my partner began displaying similar symptoms, which felt oddly coincidental, leading us to wonder if we might both be coming down with something contagious. Today, I still feel somewhat fatigued and experience occasional aches similar to those I usually get when battling a virus. Thankfully, my condition doesn’t seem to be deteriorating. I'm searching for my thermometer to monitor my temperature, but so far, it doesn’t seem like I have a fever. Typically, my doctor prescribes antibiotics whenever such an abscess occurs, even if it has already started to drain. However, I struggle with antibiotics due to my IBS and ulcerative proctitis, and there appears to be conflicting information regarding their necessity when a cyst is draining and healing on its own. This would also mark my fourth course of antibiotics within the past eight months. I’m currently awaiting a response from my healthcare provider, but in the meantime, I would appreciate any insights from others who might have experienced similar situations. Thank you for your help!
