Concerns About Breast Changes?
Hello everyone, I’m an 18-year-old female, and since I was roughly 13, I’ve experienced sensitivity in my breasts. Initially, I dismissed it as a normal part of their development. However, I’ve noticed something unusual lately: my left breast appears larger than my right. I would estimate the sizing—my right is probably a B or C cup, while the left could be a C or D cup in UK sizing. At first, I thought the growth differences were just part of normal development, but the contrast is now quite prominent, and the left breast tends to be more sensitive. I've checked for lumps before, but I’m unsure about what else to feel for aside from just that. I haven’t detected any lumps, and I’m curious if there might be other explanations for this discrepancy in size and sensitivity. Any insights would be appreciated!

It's completely understandable to have concerns about changes in your breasts, especially when you've noticed some differences in size and sensitivity. Let's break this down.
Main Points:
- Breast size and sensitivity differences can be normal, especially at your age.
- It’s important to monitor for any new changes and understand what to look for.
Explanation: Breast development can vary significantly from person to person, and it's normal for one breast to be slightly larger than the other. This is common, especially in younger women whose bodies are still developing. Sensitivity can also fluctuate due to hormonal changes related to your menstrual cycle or other factors.
However, it's always good to be aware of your body and any changes that seem unusual. Since you've described that your left breast is not only larger but also more sensitive, it's wise to keep an eye on it, even though you haven't found any lumps.
Next Steps:
-
Self-Examine: Continue to check your breasts regularly. Use your fingertips to feel around your entire breast area for any new lumps, firmness, or unusual changes in texture. Pay attention to changes in shape, size, or skin texture.
-
Track Your Cycle: Note how breast sensitivity varies with your menstrual cycle. If sensitivity increases significantly or remains consistent outside of your cycle, this could merit further investigation.
-
Normalize Your Concerns: While breast asymmetry is common, if you notice any other symptoms like unusual pain, discharge from the nipple, or persistent changes, be sure to acknowledge these as potential signs to monitor.
-
Review with Education: Educate yourself about breast health through reliable sources like breast cancer organizations or healthcare guidance. This will help you feel more in control and informed.
-
Schedule a Checkup: If the size difference becomes more pronounced or you're worried about the sensitivity, consider visiting a healthcare professional for a clinical exam. They can provide reassurance and check for any underlying issues.
Remember, it's good to ask questions and seek reassurance about your health. You're not alone in worrying about changes to your body, and it's perfectly okay to get a professional opinion if you feel unsure.

Experiencing Two Menstrual Cycles in a Month
I am a 25-year-old who gave birth a year ago and I am currently breastfeeding. I stopped taking the minipill about a month ago or possibly less. After giving birth, I had my first menstrual cycle in June, which seemed to follow a normal pattern. However, in July, I experienced two periods. Now, I find myself starting my second period this month just a week after the last one. Is this typical, and should I expect things to return to normal soon? Additionally, the blood appears to be a dark brownish color, is not heavy, and seems to have clots.
Seeking Clarity on Sudden Health Issues: A Boyfriend's Struggles
I’m reaching out for help on behalf of my boyfriend because I genuinely feel overwhelmed and confused about our situation. This will be quite detailed, as I want to provide as much context as possible. I'm extremely eager for assistance to understand what might be going on with him. **Summary of the Situation** Rapid onset of knee discomfort, a stiff neck, fever, and backache. Tests for meningitis have returned negative, and we are awaiting results for Lyme disease.

Shortly after that, he experienced significant shortness of breath and chest tightness, leading me to insist he visit the emergency room. The attending doctor indicated that the fainting was likely due to overexertion. He has an aversion to hospitals due to his past heart problems and opted to leave against medical advice before any tests could be conducted. **Current Health Concerns:** **Tuesday, August 19:** - He complained of a clicking sensation in his right thumb, which began swelling that same evening, rendering him unable to bend it. **Wednesday, August 20:** - At 5 a.m., he texted me about severe thumb pain that was preventing him from sleeping. He took paracetamol for the discomfort and decided he needed to go to the ER due to significant swelling. - After x-rays, he was diagnosed with a torn ligament in his thumb; he received treatment and was instructed to take ibuprofen and Tylenol and return if the situation worsened. >!Later, I discovered that this injury stemmed from him striking a wall in a moment of distress.

He also mentioned a throbbing thumb joint and that he was heading to the ER. His fear of hospitals and his stubborn nature made this decision seem serious. - Once at the hospital, seven blood vials were taken, along with x-rays of his knees. - I sent my mom to check on him since I'm currently studying far away and his family is overseas. I found out he also has neck pain. Unfortunately, despite the wait, he was prioritized for treatment due to concerns regarding meningitis. - By 8:30 a.m., I received an update: "No signs of meningitis. He’s being discharged but needs to see a rheumatologist for further testing to rule out Lyme disease and other viral infections that can cause arthritis. He was also found to have a fibroma in his knee, which may not be related to his knee pain but requires further evaluation. Overall, I feel a growing sense of urgency and worry as I navigate this experience with him from afar, seeking any insights or support that can help us through this difficult time.
Widespread Hives Concern
I am sharing this on behalf of a friend. She is a 30-year-old female, standing at 5'6", and is of Caucasian descent. Her current medications include Lexapro and Wellbutrin, and she hasn’t been diagnosed with any medical conditions outside of depression. Just a heads up, her job involves working at a hospital, which may or may not be relevant to her situation. On August 21st, she woke up to discover hives covering her entire body, with the exception of her face. While they are somewhat itchy, the discomfort isn't overwhelming at this point. Unfortunately, by today, the situation has escalated and the rash has spread more extensively. She consulted with urgent care, but the healthcare professionals were uncertain about the cause. They recommended taking Benadryl and Zyrtec; however, she hasn’t experienced any relief with those medications. I’m trying to find some insight into what could be triggering this reaction and what her subsequent steps might be. Any advice would be greatly appreciated!
Navigating a Complex Spine Issue in a Toddler: Neurosurgery or Dermatology?
Recently, we became aware of a noticeable bump on the spine of our 2.5-year-old child. After discussing our concerns with his primary care provider, an X-ray was performed, which yielded normal results. However, since the lump had not improved, the doctor recommended an ultrasound. The ultrasound findings indicated a "complex lesion" in the lower back, measuring approximately 0.7 x 0.7 x 0.4 cm and located 0.1 cm beneath the skin. Due to interference from the spinal processes, the results could not entirely rule out the possibility of a tract extending into the spinal canal. Consequently, we received a referral to pediatric neurosurgery for further evaluation, and they mentioned that an MRI would be scheduled. Today, I received a call from the neurosurgery office, where the nurse expressed that she believes this issue may be more appropriately handled by a dermatology specialist, a viewpoint that contrasts with our primary caregiver's opinion. Currently, I find myself uncertain about whether to advocate for the MRI and further neurosurgical consultation or to proceed with the dermatology route as recommended. The lump has caught the attention of everyone who sees it, adding to my concern.
Persistent Daily Headaches Over Several Months
I am a 30-year-old woman, standing at 5'8" and weighing 165 lbs, and I’ve been experiencing daily headaches for at least six months straight. My medical history includes polycystic ovary syndrome (PCOS) and bipolar disorder type II. For about two years, I was treated with Lamictal at a dosage of 100 mg, but I discontinued it in May 2025. Additionally, I've experienced two concussions during my teenage years, and I suffered a head injury at the age of 21, which resulted in a laceration above my right eyebrow that required stitches. Since that incident, I have occasionally felt tingling sensations in the area around my right eyebrow and extending towards my hairline. Each day, my headaches commence first thing in the morning and often persist throughout the morning. While they generally lessen during the day, they tend to intensify again before I go to sleep. The pain is concentrated in the frontal region of my head and sometimes correlates with pressure around my right eye, which can lead to episodes of watering. Initially, I thought these headaches might be due to seasonal allergies, but as they continued daily for an extended period, I grew concerned and sought care from a new doctor, as I did not previously have a primary care physician. My doctor recommended a brain MRI without contrast, which came back normal, as did an ophthalmology evaluation. The ophthalmologist noted elevated pressure in my right eye compared to the left, but indicated that it wasn't at a worrisome level. I have a follow-up appointment scheduled for September 12. My doctor also prescribed Topiramate, starting at 25 mg twice daily, and Indomethacin at 25 mg as needed. Unfortunately, Topiramate has made me feel quite unwell; I experience neuropathy in my extremities, difficulty concentrating, forgetfulness, and a decreased appetite. I have not noticed any improvement with Indomethacin either. I currently have a high-stress job and am undergoing significant life changes, which I suspect might be contributing to my symptoms. However, I've never encountered stress presenting itself in this manner before. My lab results, including a comprehensive metabolic panel and a complete blood count, returned normal. There is a notable family history of dementia, Alzheimer's disease, and a brain aneurysm in my aunt, as well as occurrences of meningiomas in my great-grandmother and aunt on my father's side. There are also instances of cardiovascular issues within the family. I'm left wondering what other factors might be contributing to my daily headaches and what steps I should take next—presumably, a referral to a neurologist is in order?
