Unnoticed Firmness in Thigh Above the Knee

2/7/2026, 8:50:22 PMMale25-34

At 32 years old, I am a woman residing in Europe, with a height of approximately 165 cm and a body type that's considered average (I unfortunately don’t have access to a scale). I am diagnosed with rheumatoid arthritis and currently receive treatment with tocilizumab. Recently, I’ve been experiencing a persistent dull discomfort in my leg that has lasted for six weeks. Initially, I attributed this ache to reduced physical activity over the festive period, particularly since the weather has been quite rainy, limiting my opportunities for outdoor walking. Upon further examination, I discovered a hard, immovable lump beneath the skin in my thigh when I press down on the area. This lump is not visible externally; it can only be detected through touch. Notably, it isn't causing me any pain. Given this situation, I find myself pondering whether it would be wise to consult a general practitioner or if this concern is minor enough to dismiss. I haven’t included any images, as there is nothing to illustrate. I appreciate any guidance you might offer!

It's understandable to be concerned about the new firm lump in your thigh, especially given your medical history. The lump's firmness combined with your rheumatoid arthritis and ongoing treatment indicates it’s wise to take this seriously, even if it is not causing pain.

Explanation

A hard lump in the thigh can have various causes, including:

  • Benign growths: Such as lipomas (fatty tumors) or fibromas, which are usually harmless.
  • Inflammatory conditions: Related to your rheumatoid arthritis, which can cause localized swelling.
  • Other conditions: Important to rule out more serious issues, even if the lump is not painful.

Given that it has been present for six weeks, it's essential to monitor this change. While many lumps can be benign, your rheumatoid arthritis and the potential impacts of tocilizumab on your immune system warrant further evaluation to ensure it isn’t indicative of something requiring medical attention.

Next Steps

  1. Monitor the Lump: Keep track of any changes in size, shape, or texture of the lump. Note any new symptoms such as pain, warmth, or changes in mobility.
  2. Document Symptoms: Continue to monitor the dull discomfort in your leg, including any patterns related to activity levels, and document these.
  3. Consult a General Practitioner: Given your medication and the persistence of the lump, arrange for a visit to a healthcare professional. It's better to be cautious, especially with your medical history.
  4. Limit Activities if Necessary: While you wait for the appointment, consider limiting activities that may aggravate your leg discomfort to avoid any undue strain.

Taking these proactive steps will help ensure that your concerns are addressed properly and your health monitored comprehensively. If any symptoms worsen prior to your appointment, seek medical advice sooner.

Seeking Insights on a Mysterious Rash

I’m a 48-year-old woman with an underactive thyroid, for which I take 100mg of levothyroxine each day. Additionally, I manage PTSD and postpartum anxiety with a daily dose of 50mg sertraline. I also deal with ADHD, managing it with 60mg of atomoxetine, and I'm undergoing menopause, utilizing everol patches for hormone replacement therapy (HRT). I take magnesium supplements as well, which I initially started for the discomfort I felt while breastfeeding my two children, but I have continued to use them during menopause. Interestingly, I have felt healthier recently, despite the ongoing fatigue that comes with being neurodivergent and raising two neurodivergent children, in addition to teaching students with special educational needs (SEND). However, just a few days ago, an intensely itchy patch appeared on my right elbow, accompanied by a small cluster of raised, red bumps. Then, I discovered a similar area on my right knee yesterday—yet, thankfully, this issue seems localized, with no other spots elsewhere on my body. I've been diligent about keeping these areas clean and moisturized, but the itching is becoming quite bothersome. I'm reaching out for thoughts or suggestions regarding what this rash could be. I appreciate any insights you may have. Thank you for your time!

Ear Health Concerns: T-tube and Grommet Queries

To provide some background, I am a 35-year-old male who does not smoke and have undergone two surgeries involving grommets in my ears. During a recent consultation, there was a discussion about inserting a T-tube during what would have been the third procedure, but I have not received any definitive information about whether that was done; I may have only been fitted with titanium grommets instead. It has been roughly five years since my last operation. Just prior to Christmas, I experienced a severe ear infection, and my general practitioner noted that she couldn't locate a grommet in my right ear. Thankfully, the infection resolved, and my hearing improved—what a relief! However, for the past week, I’ve been encountering some odd hearing sensations, particularly a feeling of fullness, almost as if there’s excessive wax. Out of curiosity, I lightly probed my ear (not too deeply!) and noticed something on my finger. I initially expected it to be hardened wax, so I ordered an otoscope from Amazon to investigate the situation before using any drops to clear it out—just for scientific purposes, of course! Let me clarify, I haven’t ventured too deeply because I’m apprehensive about causing any harm. It seems that both of my ears would benefit from a little cleaning, but I’m particularly concerned about the right ear, which has what appears to be a tube positioned quite far out. Is this typical? Should I seek professional evaluation? Is there a possibility of something more serious, like a brain-eating organism?

Elevated Blood Troponin Levels

As a long-distance runner averaging around 40 miles weekly, I recently left the hospital after being admitted due to chest discomfort. Although my ECG readings were within normal ranges, my blood troponin level was significantly elevated at 125, far exceeding the standard maximum of 14; this contrasts with my level of 45 recorded back in November. A chest X-ray also came back clear, leading to my discharge, but I am feeling quite anxious because the underlying reason for my elevated troponin is yet to be determined. Is there anyone who might have insights into possible causes? I have no family history of cardiovascular issues.

Concerns About My Father's Mole

My father, a 65-year-old man weighing 80 kilograms and standing 175 centimeters tall, has a mole that he insists has been present for two decades. Recently, he mentioned that it appears to have grown larger and has changed in color, becoming darker. Despite his reassurances that there is no need for a medical evaluation, I can't help but feel anxious about the situation. My dad has a tendency to exaggerate, which adds to my worries.

Understanding Nasal Vestibulitis: Seeking Insights

Greetings, I’m a 29-year-old female in good health, and I’ve recently experienced a peculiar set of symptoms. For the last week, I perceived sensations akin to sinus pressure accompanied by a runny nose, which produced clear mucus. I must admit that I have had a habit of nose-picking, albeit unconsciously, and at that point in time, I had developed a small injury on the rim of my nostril. Beginning Wednesday, I noticed the emergence of new symptoms. The most prominent issue now is pain in my nose, particularly along the bridge, which has become so sensitive that even the slightest touch triggers a sharp, throbbing discomfort. This pain has shown some relief with Panadol, and occasionally, applying cold or warm compresses helps. However, swelling has started to manifest, prompting me to reach out to my physician. They advised me to get an X-ray of my sinuses, which I underwent on Friday, revealing no abnormalities. The skin around my nose appears slightly pink, and while there is some swelling that has begun to extend toward my cheek, it isn’t significant. After taking Panadol, I generally feel a marked reduction in pain. The discomfort mainly resides in my nose area between my eyes but also radiates to my forehead, behind my eyes, and along my eyebrows. I consulted with an internal medicine physician today since my regular doctor was unavailable. They seemed uncertain about the exact nature of my condition. Their suspicion points to a localized infection possibly stemming from my previously mentioned nostril wound, which appears to have healed but might have created a pathway for infection. They expressed confidence that it isn’t sinusitis, unless it involves the ethmoid sinuses. Furthermore, they assured me that this is not a severe infection due to the absence of fever and lack of pain when I move my eyes. They prescribed me Augmentin, for which I am thankful. If I do not notice any improvement in a few days, they suggested that I consult with an Ear, Nose, and Throat (ENT) specialist and consider having blood tests to prepare for a facial CT scan. I must admit that I struggle with significant health anxiety, leading me to fear that this situation could escalate to involve my eyes or brain, with dire consequences. Although I have sought reassurance through ChatGPT, I would genuinely value any additional insights or advice on my condition!
