Concerns About Girlfriend's Health: Abdominal Pain and Bleeding
Hi everyone, I'm reaching out for some insights regarding my girlfriend, who is 23 years old. She was recently treated for a urinary tract infection and was given Nitrofurantoin 100mg. Unfortunately, she only took the medication for four days because of side effects, and, thankfully, her UTI symptoms resolved shortly after. However, about a week later, she began to feel severe discomfort on her side, near her kidney, and today she's also experiencing cramps in her lower abdomen along with some vaginal bleeding that is brown in color. While I understand this may not be common, is it possible that the medication triggered this reaction? If the medication isn’t the cause, what else might be responsible for these symptoms? Notably, her menstrual cycle is expected to begin in approximately 12 days. Any advice would be greatly appreciated!

The symptoms your girlfriend is experiencing, including abdominal discomfort, lower abdominal cramps, and brown vaginal bleeding, are concerning and should be approached carefully. While it's possible that the Nitrofurantoin may have contributed to her current discomfort, there are many potential causes for these symptoms that need to be considered, including complications related to the urinary tract infection (UTI), menstrual cycle irregularities, or other gynecological issues.
Explanation
-
Medication Side Effects: Nitrofurantoin can cause gastrointestinal side effects and may lead to other reactions, but severe abdominal pain and vaginal bleeding are not typical side effects of this medication.
-
Potential Causes:
- Urinary Issues: If her UTI was not fully resolved, or if it has resulted in a kidney stone or pyelonephritis (kidney infection), these could cause significant pain and symptoms.
- Menstrual Cycle: As her menstrual period is approaching, the cramps could be related to ovulation or an early period.
- Other Gynecological Conditions: Conditions such as ovarian cysts or pelvic inflammatory disease (PID) could also be responsible for pain and abnormal bleeding.
Next Steps
-
Monitor Symptoms: Pay close attention to her symptoms. If the pain worsens, or if she experiences additional symptoms like fever, increased bleeding, or severe nausea, this would be a strong indication for immediate evaluation.
-
Hydration and Rest: Encourage her to stay well-hydrated and rest as much as possible to ease the discomfort.
-
Seek Medical Attention: It is important for her to consult a healthcare provider as soon as possible given the combination of abdominal pain and vaginal bleeding, especially because this is a change from her normal condition.
-
Symptom Diary: It might be helpful for her to keep track of her symptoms—when they occur, their intensity, and any other factors (like food, activity, or cycles) associated with them. This information can be valuable for her healthcare provider.
-
Discuss Side Effects: If she has any concerns about past medications, discussing those with her doctor can help clarify whether they could play a role in her symptoms.
Please reassure your girlfriend that seeking help early is the best way to ensure her health and well-being. It’s always better to err on the side of caution when it comes to new or changing health symptoms.

Urgent Concern: Potential Double Dose of Vyvanse
I am a 42-year-old woman weighing 163 pounds, and my only regular medication is 40mg of Vyvanse, which I take primarily to manage ADHD and, to some extent, my Narcolepsy type 1. Additionally, I have asthma and experience occasional tachycardia. Although I've never been diagnosed with POTS, my two children have been, and I have some past issues with a tilt-table test from the 90s that resulted in lost records. I also deal with OCD, which, while generally managed, has previously led to confusion regarding my medication regimen. Right now, I'm uncertain if I may have overdosed or if my OCD is influencing my thoughts. Given my ADHD and experiences of dissociation, my memory is sometimes unreliable. Typically, I take my medication right after returning home with my dogs around 6:30 PM, though I often end up taking it later, around 8:15 AM after driving my kids to school. As of now, it’s 8:35 AM. At 8:15, shortly after I took the medication, I had a sudden thought that perhaps I had already taken my dose for the day. Now, I find myself at a loss about what steps to take. Should I attempt to induce vomiting due to the potential risk of having ingested 80mg of Vyvanse, or would it be wiser to wait and monitor my condition before reaching out to my doctor if any unusual symptoms arise? I appreciate any guidance on this matter.
Concerns About Daily Mucous in Throat After Nosebleed
For the past week, I have been experiencing a concerning issue where I find myself expectorating what seems to be old blood mixed with mucous. This has been occurring daily since my recent nosebleed, and I can’t shake the feeling of anxiety that it’s causing me. While I don't have any other major symptoms, the situation is weighing heavily on my mental health.
Anxiety about Resuming Antidepressants and Rare Disorders: Seeking Guidance
I am a 21-year-old individual assigned female at birth, standing at 166 cm and weighing 48.6 kg, which is below the ideal range for my height. I am currently addressing copper deficiency resulting from celiac disease, which I am still in the process of recovering from. Additionally, I have autism, obsessive-compulsive disorder (OCD), and treated Hashimoto's hypothyroidism. I do not smoke or consume alcohol. I am considering the reintroduction of fluoxetine, a medication I've previously taken for four years without any adverse effects. After a nine-month hiatus, I'm planning to start it again at a low dosage and gradually increase it. However, I am genuinely frightened about the possibility of developing Persistent Genital Arousal Disorder (PGAD), a very uncommon condition that has occasionally been associated with antidepressants. Compounding my worry is the fact that I already suffer from chronic pelvic pain issues, including vulvodynia and potential pelvic floor dysfunction. My gynecologist has suggested that fluoxetine might help with my vulvodynia, which is why I initially started the medication for my OCD. I would greatly appreciate it if anyone could provide insights or share clinical experiences regarding the likelihood of someone like me developing PGAD when restarting fluoxetine slowly, particularly in light of existing pelvic issues. I'm facing a significant internal struggle due to this anxiety and desperately require clear, evidence-based information to make an informed decision about whether it is prudent to try this medication again. Even a small risk is concerning, and I truly need to ensure that the likelihood of complications is as low as practically feasible in medical terms. I'm in need of this medication for several reasons, which leaves me feeling quite conflicted and in distress. Thank you for your attention and support.
Is This Related to Anxiety?
Female, 27 years old, not a smoker, weighing 260 pounds, and with a straightforward health background aside from experiencing anxiety. I'm thrilled about an upcoming girls' weekend where I’ll be attending a book convention, but I’m a bit on edge due to a UTI I dealt with last week, for which I was prescribed Macrobid. My anxiety, particularly around health issues, tends to amplify situations like this. Over the past three days, I’ve experienced sporadic itchiness in both ears. I haven’t been swimming or exposed to anything out of the ordinary, only having visited a lake more than a week ago. While there’s no pain or discharge, that itchiness has been quite bothersome. Now, with just four days to go before my trip, my anxiety symptoms seem to be intensifying; I spent most of the night heading to the bathroom and the itching in my ears is becoming unbearable. I have a scheduled visit with my general practitioner next Monday upon my return. He suggested that my symptoms may stem from anxiety, noting that my urine culture indicated a minor UTI, which Macrobid should have cleared up, and emphasized that its re-emergence aligns coincidentally with my travel plans. My dilemma is whether I should reach out to my gynecologist for a follow-up on my urine analysis or if I should seek immediate care regarding my ear discomfort?
Seeking Advice - Feeling Quite Awkward 😔
I'm a woman in my mid-40s, standing at 5'6" without any significant ongoing health concerns. I'm feeling quite uncomfortable sharing this, but I need advice. I frequently experience severe urinary tract infections (UTIs) and currently, I have an upset stomach. In my confusion, I realized that I wasn’t properly shielding my intimate area with toilet paper, and while I thought I needed to use the restroom for a bowel movement, I accidentally urinated on my hand. Complicating matters, I am also menstruating. Adding to my worry, I have a minor cut on my finger that stings. I quickly stopped what I was doing, thoroughly washed my hands multiple times, applied antiseptic, and covered the cut with Neosporin. My mind is racing with fears about the possibility of an infection or even toxic shock syndrome. I haven't been eating much over the past few days, which probably contributed to my lapse in judgment. I'm feeling overwhelmed with everything that's happening in my life right now, and this incident is adding to my anxiety. Can someone please advise me on what I should expect?
