Understanding the Side Effects of Ferrous Fumerate
A 28-year-old woman weighing 61 kg and standing at 5 feet 5 inches tall recently underwent a blood test which revealed that her iron and ferritin levels were only slightly above 8. For the past week, she has been taking one 210 mg ferrous fumerate tablet daily. However, three days ago, she began to notice some troubling symptoms, including skin itching, muscle discomfort, weakness, and cramps. Today, she developed an itchy rash that started with her ears and has since spread to her arms and chest. She is wondering if taking Piriton would help alleviate these symptoms and whether these reactions are typical side effects of the medication. She notes that there have not been any changes in her daily routine — including laundry detergent or body wash — that could account for these new symptoms. She intends to reach out to her GP for further guidance tomorrow.

It sounds like you are experiencing some concerning side effects after starting ferrous fumarate. The symptoms you described—itching, rashes, muscle discomfort, weakness, and cramps—are not commonly listed as typical side effects of ferrous fumarate, although they can occur in some individuals.
Explanation:
Ferrous fumarate is a type of iron supplement often prescribed for iron deficiency anemia. While some people may experience digestive side effects like constipation or nausea, skin reactions and muscle pain are less common. Your symptoms could indicate an allergic reaction to the supplement or another issue unrelated to the iron itself.
Given that you developed an itchy rash that started in your ears and spread, it's important to consider the possibility of an allergic reaction, especially since you're also experiencing other symptoms like muscle discomfort and weakness. Piriton (Chlorphenamine) is an antihistamine that can help alleviate itching and rash associated with allergic reactions. However, using it without prior consultation can mask symptoms that may need further examination.
Next Steps:
-
Stop Taking Ferrous Fumarate: Given your symptoms, it would be wise to discontinue the iron supplement until you have consulted with your GP.
-
Assess Your Symptoms: Monitor your symptoms closely. If you notice any worsening, such as increasing rash size, swelling, or difficulty breathing, seek medical attention immediately.
-
Consider Taking Piriton: You can consider taking Piriton to relieve the itching and rash, but consult with your GP as soon as possible for guidance on the use and dosage.
-
Prepare for Your GP Appointment: Document your symptoms, their onset, and any other medications or supplements you are taking. This will help your doctor assess the situation more effectively.
Please remember to reach out to your GP as planned, as they will provide personalized recommendations and help determine the next steps regarding your iron needs and the rash. Take care, and I hope you find relief soon!

Could This Be a Chemical Burn?
Age: 34 Gender: Female Height: 5 feet 6 inches Weight: 180 pounds Ethnicity: Caucasian Symptoms Duration: 14 days Affected Area: Both hands Patient History: 34-year-old female with a medical history of dysphasia and various gastrointestinal issues. Current Medications: Being treated with Zosyn and Bactrim. About two weeks ago, while cleaning the bathroom using "Scrubbing Bubbles Foam Bathroom Spray," I did not utilize gloves. The following day, I noticed my hands were turning red and peeling. Since that initial observation, the condition has steadily worsened and become more persistent. I am experiencing a burning sensation in my hands, which feel hot and extremely dry. The discomfort is reminiscent of having a lighter passed over my skin. In an attempt to alleviate the symptoms, I have tried several treatments, including 1% Hydrocortisone, 2% Mupirocin (which I already had at home), Aquaphor, and TubbyTodd's unscented ointment, yet none have provided relief. I wore a ring on the day of the incident, but after removing it, I still notice a red mark and peeling in that area. I am uncertain whether this issue stems from a chemical burn or eczema, and I am unsure if it warrants an urgent care visit, especially since my primary care physician is unavailable until August 5th. The same goes for my dermatologist. I have included a picture from the first day as well as a recent photo; my right hand exhibits the same type of burn in a similar location.
Persistent Clitoral Discomfort for Over a Year
Hi, I'm a 24-year-old female dealing with chronic pain localized mainly on the left side of my clitoris, lasting for more than a year. The sensations I experience seem to be nerve-related and are often described as a burning feeling, tenderness, or an uncomfortable rawness and heightened sensitivity. The pain is relatively consistent, with little fluctuation, but anything that puts pressure on the area, like tight clothing, crossing my legs, or specific sleeping positions where my legs touch, intensifies the discomfort. Despite being on gabapentin for several months, I haven't seen much improvement. Additionally, I was given amitriptyline for a month, yet it didn’t provide significant relief. I also tried clobetasol ointment briefly, which did lessen some redness and swelling but didn’t help with the pain itself. There are no signs of lesions or unusual discharge, although I sometimes experience a heightened burning sensation during urination when the area is already irritated. This ongoing pain significantly impacts my daily life, and I wonder if it might be connected to conditions like clitorodynia, pudendal neuralgia, or another nerve-related issue. I'm looking for suggestions on what to do next, including the possibility of trying other medications, nerve blocks, topical applications, imaging tests, or pelvic floor therapy. I came here hopeful and would greatly appreciate any guidance you can offer!
Severe Leg Pain with Numbness: Should I Seek Urgent Care?
I am a 27-year-old assigned female at birth, standing at 6 feet tall and weighing 170 pounds. This morning, I woke to a deep, bruise-like ache in my shin just beneath the knee. Throughout the day, that discomfort has intensified into a burning sensation, and I’ve noticed my foot starting to feel numb. While walking is somewhat painful, I am still able to manage it. I’ve taken some Tylenol in hopes of easing the discomfort. I should also mention that I’m experiencing quite a bit of nausea and fatigue, though this might not be related to my leg issue. Given these symptoms, do you think I should seek urgent care right away? I’m a bit reluctant to do so since I’m currently traveling for work and don’t know the local clinics well. If the pain continues, my plan is to wait until the weekend is over and visit my usual urgent care when I return home.
Struggling with Thyroid Problems: Seeking Advice
Hello everyone. I am a 20-year-old female and have been facing severe hormonal imbalances for over a year. I'm reaching out for advice from anyone with a similar experience because I feel utterly lost. Around September last year, I unexpectedly gained 5 kg within a span of 20 days. Shortly after this, my menstrual cycle became erratic, leading to periods that are now only occurring every couple of months, and at times, not at all. The entire situation has caused me a lot of stress and confusion. For the past seven months, I have been on a diet, managing to lose a mere 5 kg. Despite maintaining a calorie deficit, meticulously tracking my intake, and eating healthily, I inexplicably gained 1 kg this week. This weight increase is not due to water retention; I monitor my weight daily, and this feels more like a persistent issue rather than normal bloating. My weight rose from about 64.3 kg to 65.7 kg in just three days and remains at that level. It seems like my condition is deteriorating. Additionally, I am experiencing the following symptoms: • Severe constipation that results in pain and dizziness, accompanied by what feels like elevated blood pressure during bowel movements. • Significant hair loss that surpasses normal amounts. • Persistent fatigue, low energy, and a general feeling of heaviness. • Sudden bouts of sadness and emotional distress linked to my weight and body image. • Inconsistent thyroid test results — I often oscillate between hypothyroid and hyperthyroid diagnoses with no clear pattern. • Elevated prolactin levels, which reached 60.6 ng/mL at one point, led to a prescription for cabergoline that reduced the prolactin but didn’t alleviate my other symptoms. • Irregular and at times, painful menstrual periods. • Variability in my TSH levels, yet despite numerous consultations, no physician has provided a definitive answer or treatment strategy. The common response is either to run more tests or suggest marriage as a remedy. Over the past six months, I have undergone about ten blood tests. Doctors have performed physical examinations of my neck and reported no abnormalities, such as swelling or nodules. They claim my thyroid is functioning "normally," although my symptoms suggest otherwise. I currently reside in Syria, where access to quality healthcare is quite limited. Consulting with an endocrinologist is not straightforward, and second opinions are hard to come by. Some physicians have even remarked, "Get married, and your hormones will stabilize," which is both infuriating and unhelpful. I harbor concerns that something significant may be overlooked, and I’m unsure about my next steps. Is it feasible to have thyroid issues without visible swelling? Can thyroid function fluctuate dramatically like this before achieving stability? Is it possible that some individuals never fully recover despite receiving treatment? If anyone has faced similar struggles or has insights to offer, I would greatly appreciate your input. I just want to regain control over my life and body. Thank you for your support.
Reevaluation of Renal Lesion After Extended Active Surveillance
My mother, aged 82 and weighing 145 pounds, remains in good health and leads an active lifestyle. We have recently encountered a significant update in her medical evaluation concerning a suspected renal cell carcinoma (RCC). Enclosed are screenshots from various scans alongside a comprehensive summary document detailing the findings and measurements, as well as the report from the newly consulted radiologist. **Recent Radiologist Analysis** The latest report states: "Due to the fluctuating size of the right renal lesion over time, along with observed blood presence on one non-contrast CT scan and a fluid level on at least one ultrasound, this lesion is most likely a hemorrhagic cyst. Furthermore, there are also indications of hemorrhagic cysts in the left kidney." I utilized a summary of findings I compiled to engage with ChatGPT, which assessed that the likelihood of the lesion being RCC is considerably high, rated at approximately 65 to 75%. **ChatGPT Analysis:** **Cystic Renal Cell Carcinoma (RCC): Likelihood - 65-75%** **Reasoning:** Key factors include an enhancing solid component, growth over intervals, notable cortical bump, increased complexity, and consistent size escalation (particularly from 2023 to 2025). Additionally, the Bosniak classification indicates features typical of **Bosniak III-IV**, suggesting a malignancy risk of 50-90%. What deeply worries me is that the latest radiologist's report altered measurements considerably from earlier assessments. The accompanying screenshots I possess corroborate the previous evaluations. **Note:** My earlier post was mistakenly deleted, prompting this new inquiry. Your support and insights on this matter would be invaluable.
