Strange Hard Lump on My Pinky Knuckle - Seeking Advice
I have noticed an unusual hard mass appearing on my pinky knuckle of the right hand. It's characterized by a red hue and feels dense, remaining unchanged despite applying ice. I am curious if anyone has insight into what this could be. When I position my hands side by side to compare, this bump is noticeably twice as high as the knuckle on my other finger. Unfortunately, I can't upload an image, but I hope my description provides a clear enough picture of the situation. Any thoughts?

It sounds like you’re dealing with a hard lump on your pinky knuckle that hasn’t changed even after applying ice. This could indicate several possibilities, including a cyst, a ganglion, or even a form of arthritis. The fact that it is red and feels dense could suggest inflammation or irritation as well.
Explanation:
- Cyst or Ganglion: These are fluid-filled sacs that can develop in various areas of the body, including the knuckles. They often don’t cause pain but can feel firm and appear raised.
- Arthritis: Conditions like osteoarthritis or rheumatoid arthritis can lead to similar swellings due to joint inflammation.
- Injury: If you’ve had any recent trauma to your hand, this could also lead to lump formation due to a hematoma or localized swelling.
Next Steps:
- Monitor: Keep an eye on the lump for any changes in size, color, or sensation over the next week.
- Gentle Care: Avoid excessive use of the hand to prevent further irritation. If it’s painful, consider using over-the-counter anti-inflammatory medications like ibuprofen, if appropriate for you.
- Ice and Elevation: Continue to apply ice intermittently to manage any discomfort and keep the hand elevated when possible.
- Documentation: Take notes about any additional symptoms you notice, such as pain, mobility changes, or swelling in other areas.
- Consider a Soft Bandage: If the lump is bothersome, a soft wrap may provide some cushioning and support.
If the lump persists without improvement, increases in size, becomes painful, or if you notice other concerning symptoms (like stiffness or difficulty moving your fingers), it may be wise to seek further evaluation to get a clear diagnosis and appropriate treatment options.

Struggling with Unexplained Ear, Throat, and Nose Issues for a Year
I'm feeling quite hopeless and am seeking any insights or recommendations. I’m a 30-year-old woman residing in the UK. Since August 2024, I've been experiencing strange discomfort in the middle section of my throat on the right side whenever I swallow food or drink. This pain has become so intense that it forces me to stop eating partway through my meals. Additionally, this discomfort often occurs alongside pain in my right ear, an odd sensation of moisture in that ear despite no visible signs of infection, general body aches, and an overall feeling of being unwell. Tests revealed my blood work is normal, and antibiotics provided no relief. These symptoms have been recurring every couple of weeks. Sometimes the throat pain is localized near my upper lymph nodes or lower throat, but it consistently affects the right side. After consulting with an ear, nose, and throat specialist, I was informed there were no noticeable masses present, and my ear issues seemed to be disregarded and attributed to dental problems instead. However, I maintain regular dental check-ups every six months, and my dentist has confirmed my dental health is good. They suggested a diagnosis of globus sensation, yet I do not feel a lump in my throat, and this explanation does not account for the entirety of my symptoms. Recently, a general practitioner suggested it might be ‘gustatory otalgia’ coupled with a wet ear syndrome, but they were uncertain about diagnostic procedures or treatment options. Lately, I have become increasingly anxious due to new symptoms, such as episodic tingling on the right side of my face. Currently, I'm experiencing pain in my right ear without any signs of infection, throat discomfort on the right side also sans infection, pervasive body aches, and fatigue, all while lacking a fever. This situation is driving me to the brink of frustration. It’s alarming that these issues have persisted for almost a year, consistently on the right side. Would it be unreasonable to request an MRI or CT scan of the head and neck region? Are there alternative tests that could be considered? My blood tests have consistently returned normal results without any indications of problems. Any guidance or support would be greatly appreciated!
My Mother's Ongoing Battle with Chronic Lyme Disease
My mother, who is 63, has been living with chronic Lyme disease for over seven years, along with Restless Leg Syndrome and possibly a few other conditions that I’m not entirely familiar with—all of which emerged after her initial diagnosis. One of the most significant hurdles she's facing is her profound mistrust of traditional medicine. I won’t delve too deeply into this topic, but I must express my frustration with the so-called alternative medicine culture, especially given the prevalence of homeopathy in Germany, where some treatments are partially covered by the public healthcare system. Despite her incapacity to walk or prepare meals independently, she continues to shun antibiotics and seeks advice from conventional healthcare professionals. Mom is convinced that antibiotics could exacerbate her condition at this advanced stage, reflecting on her past decisions with regret. She often remarks that if only she had sought proper medical treatment sooner, perhaps her prognosis would have been different. This situation has placed a significant emotional strain on my family and me, as we bear the responsibilities of her care. I desperately want to understand whether the belief that antibiotics are ineffective or potentially harmful in her current state holds any truth or if it’s an unfounded myth. Information is scarce, and I find myself at a loss. Ultimately, my goal is to ensure that she receives proper medical attention from a qualified doctor, not someone charging exorbitant fees who may further compromise her health during treatment.
Is It Safe to Split Film-Coated Tablets Without a Score?

My main question is: does splitting these pills pose any potential health risks, such as gastrointestinal problems, reduction in effectiveness, or issues related to the pill's coating?
Frustrations with Persistent Ringworm Infection
I am a 34-year-old woman, 5'7" tall, and weigh 10 stone 7. Recently, I underwent a blood transfusion due to low levels caused by excessive menstrual bleeding. I also have a history of aortic dissection and I'm currently on medication that includes fluoxetine and pregabalin. For this ongoing issue, I have been using antifungal medications: tablets, terbinafine cream, and clotrimazole cream, which I'm alternating between since the latter has proven ineffective on its own. Additionally, I've just started taking antihistamines. I'm a non-smoker and my primary concern is the spread of this infection across my thighs, which began as what I thought was ringworm. To clarify, this started a few weeks ago and despite my efforts, including fresh clothing and linens, the condition has only worsened over the past three weeks. I’ve been on the antifungal tablets for a mere eight days, yet the rash continues to expand, leaving me bewildered and unsure of how to proceed. If anyone has insights or advice, I would greatly appreciate your help. Thank you! Emma x
Seeking Clarity on Ongoing Health Issues
Hello everyone. I'm a 28-year-old woman and I’ve been struggling with various painful symptoms since March of 2025. I gave birth to my baby in January 2025, initially attributing many of my health concerns to postpartum changes. However, as new symptoms have emerged, my health doesn’t seem to be improving. **Background Information:** - I was diagnosed with celiac disease in 2016 but continued to consume gluten, which I now realize was unwise. I stopped gluten intake in early April 2025 as my symptoms intensified. - My childbirth experience in January 2025 was complication-free. - Symptoms began manifesting around March 2025. **Current Symptoms Include:** - Intense upper back pain that fluctuates, present about 75% of the time, occasionally radiating to my right chest briefly. - Intermittent abdominal discomfort. - Joint aches that come and go. - Escalating anxiety levels. - Right-sided neck pain that triggers headaches at the base of my skull. - Persistent fatigue. - In March, I experienced unusual stools that were greasy and floated, resembling cow-like stools, but this has since improved. **Medical Assessments Conducted:** - Visited the emergency room two times. - First CT scan in March 2025 indicated colitis and a benign left renal cyst, followed by a course of antibiotics. - Second CT scan in June 2025 revealed the same benign left renal cyst and a 3.3 cm cyst on the right ovary, which doesn't require further monitoring. - All routine blood tests have returned normal results, except for a drop in white blood cell count in June 2025. - Additional tests, including an ANA screen, thyroid, magnesium, vitamin B, vitamin D, C-reactive protein, and lipase, all fell within the normal range. I have upcoming appointments scheduled with gastroenterology and rheumatology, although they are a few months away. I'm reaching out to see if anyone has insights or guidance on what could be happening. I've heard that pregnancy and childbirth might unveil underlying health issues, but right now, it feels as though I’m dealing with multiple health challenges simultaneously, making it tough to connect the dots. Thanks for your help, and feel free to message me if you need more details.
