Discomfort and Mild Swelling of Lymph Nodes in the Groin Area
Hello everyone. I'm a 24-year-old woman, standing 5'7" and weighing 130 lbs. At the moment, I'm on Macrobid due to a history of urinary tract infections. I don’t smoke or drink alcohol, and I’ve been experiencing some discomfort since I awoke this morning. I decided to reach out for some opinions, as I tend to worry about my health and would like to determine if my concerns are unwarranted. To provide some context, I recently began treatment for a UTI and started taking Macrobid yesterday. Since this morning, I’ve noticed that my lymph nodes on the left side of my groin are not only painful but also slightly swollen—enough for me to see a difference. They are tender when touched, and their size is comparable to that of a pea or a small blueberry. Additionally, I suffered a severe headache last night after work and now sense that I might be developing another one. Could this discomfort be related to my UTI? Is it possible that an adverse reaction to Macrobid might result in swollen lymph nodes in the groin area? I have taken this medication previously without issues, and the only antibiotic to which I have an allergy is clindamycin. I appreciate any input you might have. Thank you!

You’re clearly experiencing some discomfort with swollen lymph nodes in your groin and a headache, which can understandably cause concern. Let's break this down and prioritize some steps to help you with your symptoms.
Overview
Swelling and tenderness of lymph nodes can occur as part of your body's response to an infection, which could potentially be related to your urinary tract infection (UTI). While it's not typical for Macrobid (nitrofurantoin) to cause lymph node swelling directly, any infection or inflammation in the body can lead to changes in lymph nodes as part of the immune response.
Explanation
Lymph nodes help your body fight infections, and when you have a UTI, it's possible for nearby lymph nodes to react. Milder headaches can also occur for several reasons, including dehydration or tension, especially if you're feeling stressed or if you've had a long day. Given that you've recently begun antibiotic therapy, it's unlikely that you're experiencing an allergic reaction to Macrobid given your prior tolerance, but any medication can cause side effects.
Next Steps
-
Hydration: Make sure you’re drinking plenty of fluids, especially water, to stay hydrated, as dehydration can lead to headaches and may help reduce the UTI symptoms.
-
Monitor Symptoms: Keep an eye on your lymph nodes. If you notice any changes in size, increased tenderness, or if you develop a fever, these could be signs of a more significant reaction or complication that may require further attention.
-
Pain Management: Over-the-counter pain relief could help with your discomfort. Ibuprofen or acetaminophen can be used to alleviate headache and discomfort, assuming you have no contraindications for these medications.
-
Rest: Make sure to get enough rest while you’re recovering from your UTI. Stress and lack of sleep can contribute to headaches as well.
-
Keep Track: Maintain a simple log of your symptoms, such as when the headaches occur and any changes in the lymph nodes. This information can help if you need to seek further advice later on.
When to Seek Help
If the swelling increases, if you develop a fever, experience severe pain, or if the headaches become more frequent or debilitating, it would be important to reach out for further evaluation.
It's normal to feel worried about unexpected symptoms, but giving attention to how your body responds and addressing issues thoughtfully can often lead to improvement. Please take care, and let me know if you have any further questions!

Severe Abdominal Discomfort
An 18-year-old male, with no history of smoking or current medications, finds himself at home, surrounded by his sleeping family. He stands approximately 5 feet 11 inches tall and weighs around 220 pounds. Lately, he has been experiencing persistent discomfort in the lower left side of his abdomen. This sensation has intensified recently, culminating in a bout of vomiting, which was notably different this time, presenting more solid material rather than the usual liquid with some fragments. The level of pain has escalated significantly, leaving him uncertain about seeking medical assistance at this moment. What steps should he take?
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!
Normal MRI and EMG Reveal Nerve Slowdown
Greetings, I’m a 23-year-old female seeking guidance about some health issues I’ve been experiencing. Recently, I've noticed weakness in both my hand and arm, particularly in my dominant hand where grip strength has been notably diminished. After undergoing an EMG, the results indicated that my nerves are exhibiting a slowdown. However, my MRI results were unremarkable. To address some swelling I experienced, I was prescribed a course of steroids (4mg for a few months), which alleviated some of the issues, yet I still experience residual swelling in my hand. Often, my hand feels cold, and I notice a popping sensation when I move my fingers. Despite these sensations, I do not have any numbness or tingling, and the swelling appears sporadic. The pain I endure is quite severe, described as a hammering sensation throughout my hand. On occasion, I take ibuprofen (600mg) for relief, but it proves to be somewhat ineffective. My wrist itself seems fine, but my orthopedic specialist is considering a diagnosis of carpal tunnel syndrome (CTS), even though my symptoms don’t align with typical CTS indicators. I would greatly appreciate any advice or insights you may offer!
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.
