Concerns About Possible Kidney Infection After UTI Treatment
I’m a 21-year-old female, standing at 5’1" and weighing 190 pounds. At present, I am on a regimen that includes macrobid at a dosage of 100 mg and lexapro at 10 mg, which I have been taking for the past four years. Last Sunday, I received a diagnosis of a urinary tract infection (UTI). My symptoms had begun the previous Thursday, initially leading me to believe that I was just experiencing some discomfort due to a bruised cervix. However, once I started noticing blood in my urine on Sunday, I decided to visit my doctor, who confirmed the UTI. At that point, I was not experiencing any pain in my back. I began treatment with bactrim shortly after the doctor's visit, but due to a mild allergic reaction, I switched to macrobid the following day, which was Monday. Today, I’m feeling quite unwell—experiencing a headache and general body discomfort. After work, I rested for a bit and awoke feeling extremely fatigued, as if I had been run over by a truck. My body aches persist, I’m slightly dizzy, and the headache remains. Additionally, my nose is congested and running, and I’m battling nausea and a diminished appetite. I suspect I might have a low-grade fever as well. I managed to eat dinner, albeit with some effort, and took my third dose of macrobid along with ibuprofen for the headache. While the headache has improved somewhat, I still don’t feel good overall, and I have a mild ache in my lower back. Interestingly, most of my UTI symptoms have subsided—my urine appears normal, and I no longer experience urgency or discomfort. However, I am now left feeling ill. I’m beginning to question whether these sensations are side effects of the antibiotic or if I might be developing a kidney infection instead.

It sounds like you’re facing quite a challenging situation with your recent UTI treatment and current symptoms. You are right to be mindful of your health, especially given the changes in how you feel after starting your antibiotics.
Main Points:
- Your current symptoms could be due to the antibiotic, a viral illness, or a possible kidney infection.
- Monitoring for signs that could indicate a kidney infection is important.
- There are specific steps you can take to manage your symptoms and assess your situation.
Explanation:
While it’s encouraging that your UTI symptoms have improved, the general feelings of illness, back pain, headache, and nausea could be related to several things. Antibiotics like Macrobid can cause side effects, such as gastrointestinal upset or body aches. However, an ongoing low-grade fever, persistent back pain, or worsening general symptoms could raise concern about a kidney infection, especially if bacteria from a UTI have potentially spread to the kidneys.
Next Steps:
-
Monitor Your Symptoms:
- Keep track of your symptoms, particularly any changes in your back pain and whether you develop a fever. The presence of significant fever, chills, or worsening back pain would be more concerning.
-
Focus on Hydration:
- Drink plenty of fluids to help flush out your urinary system and support overall hydration, which is crucial during antibiotic therapy. Aim for at least 8-10 glasses of water daily.
-
Manage Symptoms at Home:
- Continue taking over-the-counter pain relief (like ibuprofen or acetaminophen) as needed to help with your headache and body aches.
- Rest is vital, so give your body the time it needs to recover.
-
Watch for Red Flags:
- If you notice any of the following, it's essential to seek medical attention promptly:
- Increased back pain or side pain
- High fever (above 101°F)
- Persistent vomiting
- Signs of confusion or severe dizziness
- If you notice any of the following, it's essential to seek medical attention promptly:
-
Follow Up:
- If your symptoms do not improve within the next couple of days or worsen, consider reaching out for medical advice for further evaluation and to discuss the possibility of needing a different treatment approach.
Take care, and remember to listen to your body. Each symptom you monitor can guide you toward the next best steps for your health.

High Fever and Body Pain: My Ongoing Struggle
At 24 years old, and standing at 5 feet 8 inches while weighing between 50 to 52 kilograms, I've been enduring a high fever and intense body aches for over five days without any signs of improvement. This prompted my visit to the emergency room. Upon arrival, I underwent a series of tests, including a complete blood count (CBC), CRP, and a chest X-ray in the posterior-anterior view. Fortunately, my CBC and X-ray results came back normal. However, my CRP level was alarmingly high at 43.1 mg. The doctors prescribed me cefixime at a dosage of 400 mg, along with zinc and pantoprazole. When I inquired about pain relief, the medical team assured me that I wouldn't need any, but I've opted to manage my discomfort with paracetamol, taking 650 mg extended-release three times a day. While this has successfully alleviated my fever, I still experience pervasive pain throughout my body. What are the next steps I should consider? Additionally, I was advised to return for the same tests if my condition does not improve within a week.
Expected Timeline for Thyroid Ultrasound Results
Last Friday afternoon, I underwent a thyroid ultrasound, and to my surprise, the results were available that very evening. Although I haven't received any communication from my physician, based on what I've read, it appears I may require a biopsy. I'm facing challenges in reaching the office, as my calls are directed to voicemail, and they haven't returned any calls. I'm eager to get an appointment scheduled soon, and it's causing me some anxiety. What is the usual timeframe I should anticipate between the ultrasound results being sent and my endocrinologist contacting me to arrange for a biopsy? Currently, I have four nodules, but I want to focus on the one that concerns me the most: **NODULE 1:** - **Location:** Right mid - **Size:** 1.8 cm (measured by the largest dimension only) - **Composition:** A mix of cystic and solid elements - **Echogenicity:** Hypoechoic - **Shape:** Wider than tall - **Margin:** Lobulated or irregular - **Echogenic Foci:** None with the exception of large comet-tail artifacts - **ACR TI-RADS Score:** 5 - **ACR TI-RADS Risk Category:** TR4 - Moderately Suspicious. Recommend FNA if larger than 1.5 cm; follow-up evaluations if larger than 1 cm at 1, 2, 3, and 5 years.
Could Rifaximin and Herbal Supplements Affect H. Pylori Test Results?
Hello everyone, I'm 30 years old and my current medications include 25 mg Tritico and a herbal supplement called Phytobox 4, which includes curcumin, resveratrol, and rutin, in addition to Bitterstofe, a mix of herbal digestion extracts. Today, I underwent a gastroscopy, during which they discovered some ulcers and carried out biopsies alongside a urea breath test. My concern lies in whether the rifaximin treatment I completed two weeks prior—specifically 5 days at a dosage of 400 mg twice daily—might have influenced my H. pylori test results. Additionally, I have been taking Bitterstofe, which comprises extracts from pomegranate, lavender, clove, thyme, and rosemary for about a week leading up to the procedure, along with Phytobox 4, an anti-inflammatory herbal blend that includes curcumin, resveratrol, rutin, and grapeseed extract. How likely is it that these treatments could lead to a false negative in the H. pylori tests? Thank you for your insights!
Potential Side Effects of Epidural and Steroid Injections
A 32-year-old woman from the United States, currently weighing 110 pounds, is undergoing treatment with Lexapro (5 mg daily) and hydroxyzine (25 mg on an as-needed basis). She received three steroid injections on January 29, February 12, and February 26, targeted at her coccyx, cervical spine, and knee joint. Lately, she has experienced significant abdominal bloating and an unusually heavy menstrual cycle that has persisted for nine days. She is inquiring whether these effects are typical after such injections, as the bloating has been particularly distressing, and she has also observed an uptick in her appetite. Prior to receiving the injections, she was not warned about the possibility of experiencing bloating or hormonal changes.
