Experiencing Numbness and Foot Drop in the Left Leg
Greetings everyone! I'm a 31-year-old male, approximately 1.9 meters tall (around 6 feet 2 inches) and weigh 175 pounds. I'm of Caucasian descent and don’t take any medications, nor do I consume alcohol, smoke, or partake in recreational drugs. Lately, I've been experiencing a troubling sensation in my left leg and foot, particularly when I sit with my legs crossed. The numbness is so severe that it hampers my ability to lift my foot while walking, which has led to a couple of close calls where I've tripped or rolled my ankle. Typically, this sensation subsides within the hour. Interestingly, after running 15 miles yesterday, there were no noticeable issues with my left leg. However, after crossing my legs again today, the numbness returned, and after five hours, I’m still feeling it. While the sensation has slightly improved, I continue to experience foot drop along with the numbness. I'm uncertain if this warrants a visit to a doctor or if I should seek emergency care. Any advice would be greatly appreciated.

It sounds like you're experiencing concerning symptoms with numbness in your left leg and foot drop, especially following certain positions like crossing your legs. Let’s break this down and identify how to address this issue effectively.
Main Points:
- Your symptoms of numbness and foot drop could indicate nerve compression or irritation, particularly due to prolonged positions, but they can warrant careful monitoring and further evaluation.
- While your recent physical activity did not appear to exacerbate the symptoms, their persistence after sitting may need closer attention.
Explanation:
Numbness and foot drop (difficulty lifting the foot) can be caused by several factors, including nerve compression, issues related to the spine, or even blood flow problems. Sitting with crossed legs may temporarily compress nerves or blood vessels, leading to numbness that resolves once you change positions. However, if symptoms persist after changing positions, or if they begin to affect your balance and mobility significantly, it's important to assess further.
Actionable Next Steps:
-
Change Position Reguarly: Avoid crossing your legs for extended periods. Instead, keep your legs uncrossed and shift your posture frequently to reduce pressure on the nerves.
-
Monitor Symptoms: Keep track of when the numbness occurs, how long it lasts, and any activities that influence it. Note if any other symptoms develop, such as weakness or changes in bladder/bowel function.
-
Evaluate Activity and Rest: Since running did not cause issues, ensure you maintain balanced activity levels that don’t push your limits, but also incorporate rest.
-
Gentle Stretching and Strengthening: Consider gentle stretches for your legs and feet, along with basic ankle strengthening exercises. Ensure these are safe and appropriate by starting slowly.
-
Seek Medical Advice: Since these symptoms are recurring and are affecting your daily life significantly, it would be prudent to consult a healthcare provider for a thorough evaluation. They may suggest imaging studies or nerve conduction tests to assess nerve function and rule out any serious underlying conditions.
-
Emergency Response: If you notice sudden changes such as new weakness that affects your ability to walk, loss of bladder/bowel control, or if you develop severe pain, seek medical attention promptly.
Taking these steps will help you manage your symptoms and provide the information needed for any healthcare provider to assist you further. Please keep an eye on your symptoms, and don’t hesitate to reach out for professional advice, especially if your condition worsens.

Mysterious Symptoms Unraveled
A 19-year-old woman recently shared her puzzling health struggles. This summer, she began a course of strong antibiotics to treat recurrent vaginal infections and UTIs linked to sexual activity. Unfortunately, this led to a diagnosis of Mycoplasma hominis, for which she was prescribed two weeks of oral metronidazole and doxycycline. Initially, she experienced some relief shortly after starting the treatment; however, about a week into it, she began to notice discomfort on the sides of her lower abdomen. This discomfort soon escalated, radiating down to her thighs and ultimately affecting various parts of her body, even extending to her ears. The nature of her pain has evolved into a migratory burning sensation that shifts throughout her body. Despite undergoing extensive testing, including blood work and stool analysis, all results returned normal. Furthermore, she has tested negative for all tick-borne diseases. She finds herself at a standstill, struggling to understand the cause of her distressing symptoms.
Understanding Your Doctor's Concern Over Normal Lab Results
Greetings, fellow internet enthusiasts! I find myself in a bit of a quandary regarding my lab results, and after some searching, I landed on this forum for insights. Let me provide some context: I'm a 20-year-old woman, 5 feet 5 inches tall, weighing 112 pounds. I do not engage in smoking or drinking and don’t take any medications, overall leading a healthy life. The only medical issue I've been diagnosed with is anemia. Throughout my life, I've had annual physical exams starting from the age of 13, which included routine blood tests. Recently, about six months ago, I faced significant fatigue, paleness, and weakness that made daily activities challenging, prompting a visit to my doctor. Upon testing, I discovered that I was severely anemic with a hemoglobin level of 9.3. In light of this, we began iron supplementation because I was quite anxious about receiving intravenous iron, and since then I've been having my blood checked monthly to monitor my progress. Initially, the improvement was slow, but my latest hemoglobin reading is now at 12.2. This morning, I had more blood drawn, and I noticed on my chart that all results fell within the normal limits of the complete blood count (CBC). However, later today my physician reached out, inquiring about my overall well-being and whether I was experiencing any symptoms such as allergies or illness. Lately, I’ve been feeling nauseous, although to clarify, I am not pregnant and have never engaged in sexual activity. Otherwise, I feel relatively well, albeit a bit fatigued. My doctor mentioned that she wishes to retest in a fortnight because my basophils, which have typically been below 0.03, have now increased to 0.08 today. While I understand this is an increase, it remains within the normal range, and the number itself is quite low. This raises the question: why is there a need for a retest? Is there anything particularly critical about basophils? Furthermore, while reviewing other trends, I observed that my platelet count is nearing the high end of normal, yet still falls within acceptable limits. Can anyone shed some light on why my doctor deemed it necessary to contact me regarding a lab result that appears normal?
Is Mylanta Safe to Use for Suspected Food Poisoning or Salmonella?
I’m a 20-year-old who’s been feeling unwell since 7 PM yesterday. While I haven't experienced much diarrhea, I am dealing with significant nausea and a strong urge to have a bowel movement after consuming two undercooked eggs. It feels akin to having the flu, and I suspect I may be starting to develop a fever. Additionally, I’m experiencing some mild chills. Given that it’s nighttime and I can’t consult my doctor, I’m wondering if it would be appropriate to take Mylanta or if I should just endure the discomfort for a while.
Years of Unrelenting Discomfort
Greetings, I am a 25-year-old man enduring severe discomfort in my calves, buttocks, and thighs for the past six years. The onset of my health issues occurred at 18, following a urinary tract infection that took considerable time to heal. Additionally, I was diagnosed with varicocele around that period. Initially, I ceased physical activity, but by the time I turned 19, I was eager to return to sports such as running and soccer. However, during one running session, I experienced a sharp pain in my left buttock, prompting me to take a break from the activity. Three months later, I began to suffer debilitating pain in my calves after walking. Each time I paused, I was plagued by muscle twitches throughout my lower body, especially in my legs and buttocks. This twitching severity increased with anxiety over time. On one occasion, when I attempted to run despite my symptoms, I nearly lost consciousness, experiencing blurred vision and intense heart palpitations at the age of 20. Since that incident, I have undergone a variety of tests, all returning normal results, including: • Electromyography (EMG) of the lower extremities • Venous Doppler ultrasound • Numerous blood analyses Due to my diminishing physical activity and increasingly sedentary lifestyle, I began to worry about my worsening condition. At 23, I felt an audible crack in my back, which was followed by persistent pain and further twitching. Now, whenever I sit for extended periods, those twitches resurface, and occasionally, I experience them even from sneezing, affecting my back and abdomen. Recently, I received some unexpected news: I was diagnosed with popliteal artery entrapment syndrome and dysautonomia. However, these conditions do not fully account for the pain I continue to endure in my buttocks and thighs, nor for the troubling twitching that occurs when I sneeze. I am feeling quite lost and overwhelmed by this situation. Moreover, I recently had a semen analysis that yielded alarming results, leading my doctor to recommend urgent surgery for my varicocele. I am anxious and frightened and reaching out for guidance!
Intensifying Coccyx Discomfort, Six Weeks Post-Delivery - Awaiting X-Ray Results

In the meantime, I would appreciate any insights or advice from anyone who may have experienced similar issues. My birthing experience was quite challenging, presenting numerous complications for both myself and my newborn, which has made recovery difficult. I struggle to sit comfortably, and the transition from sitting to standing is particularly painful. To manage the discomfort, I find myself sleeping with an ice pack pressed against the area for some relief. Over the past week, I’ve noticed a sensation of movement and grinding in the coccyx when I change positions. Any thoughts or suggestions would be greatly valued!
