Numbness in the Lower Arm
Age: 26 Weight: 138 lbs Height: 5'6" Onset: Approximately two days ago About a week ago, I sustained an injury to my foot that resulted in significant swelling. As a precaution, I have been advised to remain inactive for two weeks and will undergo another X-ray to rule out any fractures. However, over the past two days, I have experienced numbness extending from my pinky finger to the lower half of my arm. Is it possible that this numbness is related to my foot injury? Could it indicate a more serious condition?

Numbness in your lower arm, especially with recent inactivity and an injury, can have several causes, some of which may relate to positional changes or nerve compression. While it may not straightforwardly link to your foot injury, it's essential to understand what could be happening.
Explanation:
Numbness in the arm can often stem from nerve issues, such as compression from a prolonged position (like resting on your arm), or it can indicate a more serious concern like nerve damage or irritation. Given that your symptoms began two days ago, it’s possible that the numbness could be due to:
- Nerve Compression: This can occur when pressure is applied to nerves, often due to awkward positions or immobility.
- Cervical Issues: Problems in the neck area can lead to numbness radiating down the arms.
- Circulation Problems: Though less likely, issues with blood flow can also cause similar sensations.
Next Steps:
- Change Position Frequently: Adjust how you sit or lie down to alleviate any potential nerve compression. Avoid resting your arm in one place for prolonged periods.
- Gentle Movement: If comfortable, try gentle stretching or range-of-motion exercises for your arm. This can improve circulation and reduce nerve pressure.
- Monitor Symptoms: Keep track of when the numbness worsens or improves. Note any other symptoms such as weakness, pain, or changes in mobility.
- Ice/Heat Therapy: You can apply ice or heat pack to the lower arm to see if it alleviates the numbness.
- Limit Activities: Continue to follow the advice regarding your foot injury and avoid activities that may exacerbate any potential issues.
When to Seek Help:
If the numbness persists for more than a few days, worsens, or is accompanied by other symptoms like weakness, loss of control of your hand, or significant pain, it would be important to follow up for further evaluation. It’s crucial to maintain open communication about your symptoms to ensure you receive appropriate care.

Is There Cause for Concern?
As a 20-year-old woman with no significant medical history, I recently encountered an unusual situation. A few months back, I discovered a small, firm lump on my left breast. Given my history of experiencing multiple breast cysts, I initially dismissed it as inconsequential. However, during a lull at work today—I'm employed as a veterinary technician—I and a colleague decided to perform ultrasounds on each other, as a bit of light-hearted activity. She identified a lump on her own breast as well. Although I will refrain from sharing any images from her ultrasound for privacy, I do have a picture of my own lump. To my untrained eye, it appears to resemble a cyst, yet I lack the specialized knowledge in oncology to make any definitive conclusions about it.
Seeking Guidance for Ongoing Chronic Health Challenges Before College
I never imagined I'd be turning to Reddit for medical insights, but here I am. For the past three years, I’ve been grappling with severe symptoms, enduring a barrage of tests and procedures, yet I've largely been left without concrete explanations. My condition has recently deteriorated dramatically—just as I'm preparing to start college in three weeks. As I write this, I'm on day seven of relentless vomiting, and I'm desperate for any insights that could help me find answers and improve my situation before school begins. I want to truly enjoy this new chapter of my life, and I'm willing to do whatever it takes to address these health issues. For context, I’m an 18-year-old female with a normal height and weight. **Symptoms**: Below are my most troubling symptoms, highlighted in bold. **Gastrointestinal Issues**: - **Severe constipation**, despite taking the maximum prescribed dose of Linzess (290mg daily). I typically only have bowel movements once or twice a week, with instances of going up to eleven days without one. - **Daily nausea**. - **Weekly vomiting**, sometimes occurring for multiple consecutive days. - Acid reflux, occasionally leading to small amounts of vomit. - Frequent sulfur burps, despite not being on a GLP-1 medication. - Gallbladder sludge found during ultrasound, with no known cause; medication for this issue hasn’t alleviated my symptoms. - **Extreme bloating** that hampers my mobility. - **Unusual weight accumulation in my abdomen**, leading to a pregnant appearance even though I'm quite petite. **Autonomic Symptoms**: - My heart rate variations suggest dysautonomia/POTS (as confirmed by a cardiologist), though my blood pressure remains stable. - I experience tachycardia episodes 1-2 times a month without triggers; during these episodes, my resting heart rate can escalate to around 135, accompanied by heavy sweating and slight shaking, with transient elevations in blood pressure. - Temperature regulation issues. - Intense salt cravings. - Persistent thirst. **Neurological Symptoms**: - **Severe fatigue**: I’m averaging 18 hours of sleep daily. Diagnosed with idiopathic hypersomnia, but the underlying cause is still unclear. - **Frequent migraines**, occurring every few days and varying in intensity. - **Significant light sensitivity**. - A lazy eye. - Motion sickness. - Sudden weakness in my legs. - Intense leg cramps that I have experienced since childhood. **Unusual Lab Results**: - Markedly elevated alkaline phosphatase levels. - High C-reactive protein and moderately elevated white blood cell count. - Mildly raised anion gap and creatinine levels. - Low iron levels that are gradually improving. - Low electrolytes despite consuming a considerable amount of water and salt, which is perplexing. **Testing Outcomes**: - Gastric emptying study showed slightly delayed digestion but no gastroparesis. - Endoscopy and colonoscopy revealed sudden lactose intolerance; I’m now dairy-free, but no signs of IBD, celiac, or other major findings. - Sleep study identified idiopathic hypersomnia, which one doctor suspects might actually be narcolepsy, though the diagnosis was borderline, and given that treatments are similar, a repeat study may not be necessary. - Ultrasound of the abdomen, liver, pancreas, and gallbladder detected sludge in the gallbladder but returned normal results otherwise. - I also want to mention my Jewish heritage; I’m unsure if it’s relevant but thought it worth noting due to potential genetic implications. **Current Diagnoses**: - Idiopathic hypersomnia - IBS-C - Gallbladder sludge **Thank you for taking the time to read this. Your guidance and suggestions would mean so much to me!**
Understanding an Enlarged Spleen
Greetings, I am a 42-year-old female, weighing 136 pounds and standing at 5 feet 3 inches tall. For several years, I have been dealing with abdominal discomfort. While I have a diagnosis of Irritable Bowel Syndrome (IBS), the pain I experience now is distinct from my typical IBS symptoms. I experience sharp, intermittent pains located on the left side of my abdomen. Two years ago, imaging tests revealed that I had gallbladder sludge and an enlarged spleen. At that time, my physician did not view it as a significant issue. Recently, however, the pain has escalated, becoming sharper and more severe. Earlier today, I visited the hospital where they conducted blood tests along with a CT scan. The results from the blood tests came back normal, but the CT scan confirmed that my spleen remains enlarged and I now also have a gallstone. The medical team indicated that neither of these findings is likely related to the pain I am experiencing on my left side. I would like to know: 1) What steps should I take next? 2) Is this situation typical? 3) What might be the underlying causes of my spleen remaining enlarged for two years?
Can a Dermatologist Help with This? Wart Concerns
Age 29, weight 180 lbs, located in the USA. For the past two months, what I believed to be a persistent callous on the side of my index finger has been diagnosed as a wart. I have now begun treatment using wart bandages and duct tape. However, I have recently observed something concerning on my leg. Is it possible that the wart is spreading to my leg? The new growth doesn't resemble a typical ingrown hair. Should I use duct tape or a bandage to cover it temporarily?
Should I Be Concerned If My Doctor Overlooked a Serious Condition?
I’m an 18-year-old male, standing at 5'8" and weighing 170 pounds. Not long ago, I visited the emergency room due to a lump and pain in my testicle as well as discomfort in my abdomen. The diagnosis was bilateral hydrocele, and there was mention of a cyst. When I inquired about what actions I should take, the doctor indicated that surgery was a possibility, though it wasn't deemed essential. As I researched hydroceles, I noticed that my symptoms didn't quite align with the typical presentation. For instance, I am not experiencing significant pain, and stomach discomfort or dull aches in the lower back aren't commonly associated with hydroceles. Although I’ve been somewhat dismissive of my symptoms, I can't shake the anxiety that they may be indicative of testicular torsion, testicular cancer, or an inguinal hernia. My next appointment is scheduled for the 18th, but I’m uncertain if I should wait until then to see my doctor or seek immediate care at the ER. Additionally, I have hypermobile Ehlers-Danlos syndrome, which makes me prone to injuries, given I work in a warehouse and could potentially have sustained an injury. Should I be worried enough to act sooner?
