Understanding My Nerve Conduction Study Results
I'm a 24-year-old male, measuring 5 feet 11 inches and weighing 155 pounds. Recently, I've been experiencing numbness and tingling sensations down the left side of my body, affecting me from my head to my toes. I don’t have any significant medical history leading up to this issue. A neurologist recommended a nerve conduction study for both my upper and lower limbs. During our discussion about the findings, he indicated that there were no major problems detected. However, the report indicates some concerning details: For the upper limbs, the study revealed a prolonged distal latency (DL) for the median sensory nerves, a reduced conduction velocity (CV) for the ulnar nerves at the left elbow, normal conduction velocities for the ulnar nerves at both wrists, and prolonged F waves. In regards to the lower limbs, the results showed prolonged DL for the sural nerves bilaterally, decreased conduction velocities for the tibialis and peroneal nerves, delayed F waves for both tibialis and peroneals, along with extended H reflexes. What could all of this signify? The doctor merely instructed me to continue taking my prescribed medications (Clonazepam 0.5 mg and baby aspirin) and suggested that I consult with a physical therapist. However, I left the appointment without a clear diagnosis or additional guidance. I'm in search of clarity regarding these results and what they might mean for my health.

It’s understandable to feel uncertain when faced with complex medical results, especially when experiencing troubling symptoms like numbness and tingling. Your nerve conduction study indicates some abnormalities without major issues detected, which suggests that while there may be some nerve function impairment, it hasn’t reached a level that requires more aggressive medical intervention at this point.
Explanation of Results:
-
Prolonged Distal Latency (DL): This suggests that there may be delays in nerve signal transmission, which can occur due to various reasons including nerve compression or inflammatory conditions.
-
Reduced Conduction Velocity (CV): This indicates that the nerves are transmitting signals more slowly than expected, which can also imply disruption in the normal functioning of the nerves. The left elbow findings could suggest a potential issue such as ulnar nerve entrapment.
-
F Waves: These are indicative of the health of the entire nerve pathway, and their prolongation suggests a delay in signal conduction through the nerve's pathway.
-
Sural & Tibialis/Peroneal Findings: The results from your lower limbs suggest a bilateral issue where nerves may be affected more extensively, possibly indicating a generalized nerve processing or conduction problem.
These findings, combined with your symptoms, could point toward several potential conditions like peripheral neuropathies or even conditions like Multiple Sclerosis or other systemic issues, but it's crucial to understand that the results aren't definitive for these.
Next Steps:
-
Continue Medication: Follow your doctor’s advice regarding your medications. Clonazepam may help manage symptoms related to anxiety or muscle spasms.
-
Consult with a Physical Therapist: This is a valuable step to help improve your mobility and strength. A physical therapist can also provide exercises tailored to your symptoms.
-
Monitor Symptoms: Keep track of how your symptoms progress or change over the next few weeks. Note any new sensations, weaknesses, or changes in your daily activities.
-
Follow-Up with Your Neurologist: If your symptoms worsen or if you feel unclear about your current condition, don’t hesitate to reach out to your neurologist for further clarification or additional testing.
-
Lifestyle Modifications: Staying active and maintaining a healthy diet can support nerve health. Focus on well-rounded nutrition, hydration, and gentle physical activity.
If you continue to feel unclear after these steps, consider seeking a second opinion from another neurologist or specialist who might provide further insights into your condition. Your health and peace of mind are paramount.

Understanding a Small Left Retrocerebellar Arachnoid Cyst
I am a 21-year-old female. After undergoing a brain scan, I received the following findings: On the left side of my lower limb, there is mild weakness; specifically, my hip flexors and extensors show a strength level of 4 out of 5, while my knee flexion and extension are both at 4 out of 5 as well. There is no evidence of foot drop, but I'm still waiting for further assessment of my reflexes. Both the MRI of my head and the MRI of my cervical spine displayed normal results. Blood tests also returned normal levels. The MRI scans revealed that the brain parenchyma has normal signal encoding without any signs of demyelinating lesions or recent strokes. The ventricular system and the surrounding cerebrospinal fluid spaces appear clear, while the posterior fossa seems unremarkable. An incidental finding noted a small arachnoid cyst located on the left side of the retrocerebellar area. Additionally, the cervical spine shows proper alignment, with no signs of constriction in the canal or foramina, and there are no visible demyelinating lesions present. However, it was observed that some axial images were affected by motion artifacts, which might have impacted the quality of the results. In summary, there are no signs of demyelinating lesions or acute issues in either my brain or spine according to the MRI. I was advised for a medical follow-up. What does it imply to have a small left retrocerebellar arachnoid cyst? I was released from the hospital after all tests showed no abnormalities, but now, seeing this detail on my report, I feel anxious. Is there any cause for concern? My anxiety around health issues is at an all-time high right now.
Understanding and Supporting Recovery from Botulism
Duration of Symptoms: 6 months Weight: 7 kg Height: 66 cm Ethnicity: Caucasian Duration of Hospital Stay: 4 days Region: Europe Last Friday, our infant began displaying signs of fatigue and an unwillingness to feed, prompting an immediate consultation with our pediatrician. At that stage, it was suspected she might have a urinary tract infection. However, by Saturday morning, she had vomited four times in under an hour, leading us to swiftly take her to the emergency room. After undergoing numerous urine and blood tests, the medical team transferred us to the neurology department. By noon on Monday, they began to suspect infant botulism, potentially linked to environmental causes. Regrettably, stool tests were not performed over the weekend as the initial sample was deemed inadequate, but a new sample is now under examination. Medical professionals have reached out to specialists in botulism and neurology, which culminated in our daughter receiving an injection of 2 ml of antitoxins at 3 PM CET yesterday. Since then, she has shown stability, and the doctors are optimistic about receiving confirmation from the stool tests later today. We recognize the importance of patience as we await definitive results, and we understand that additional tests may be required to eliminate other potential conditions. Meanwhile, we seek guidance on how best to assist our daughter in her recovery from confirmed botulism, should that be the final diagnosis. Thank you for your support!
Understanding Lymph Nodes in the Groin Area
As a 25-year-old woman who maintains a healthy lifestyle—abstaining from smoking and drinking and actively participating in sports—I've been dealing with slightly enlarged lymph nodes in my groin for the past year. While they aren't externally noticeable, I can feel them when I touch the area. To investigate further, I underwent an ultrasound, and the results indicated the following: FINDINGS: The analysis of both groin regions showed oval-shaped structures that exhibit a hypoechoic border with a brighter center, typically associated with blood vessels. On the right side, the sizes of these formations are measured at 2.6 mm x 6.4 mm, 5 mm x 8.4 mm, and 3 mm x 9.6 mm. On the left, similar formations are noted, measuring 4 mm, 4.6 mm, 3.5 mm x 8.6 mm, and 4 mm x 10.3 mm. These appearances suggest a non-specific lymphadenopathy, free from any alarming features, likely pointing to a reactive condition, possibly stemming from inflammation. My concern is that these findings could signify something more serious, potentially malignant, which is why I am considering requesting a biopsy. I would appreciate your thoughts on this matter.
Concerns and Symptoms Overlooked
I’m a 27-year-old woman and I feel like I’m falling apart. Over the last few months, my appetite has nearly vanished. Whenever I do eat, I feel nauseous, and the discomfort persists regardless of whether I’ve eaten or not. Additionally, I have been experiencing significant pain on my left side that makes it difficult for me to function. Recently, I discovered a lump deep in my armpit, and even before I started losing my appetite, my bowel movements have not been normal. I have shared all these issues with my general practitioner, yet she has denied me any imaging tests for my abdomen or armpit and hasn’t ordered any biopsies. I’m at a point of desperation, feeling emotionally overwhelmed and crying as I write this. The constant fatigue and pervasive sadness are becoming unbearable. I’ve repeatedly requested that she allow me to undergo a CT scan or an ultrasound, but she insists on running blood tests first, attributing my symptoms to a stomach virus that she believes has persisted throughout this time. Recently, she prescribed me meloxicam. I am reaching out for guidance regarding whether my symptoms merit further scanning or evaluation.
Should I Restart Terbinafine Treatment for Ringworm After a Relapse?
I’m a 30-year-old woman dealing with a persistent ringworm condition on my hands for the past 18 months. Initially, I was prescribed terbinafine at a dosage of 250mg daily for a month, which resulted in significant improvement in my symptoms. However, my doctor concluded the treatment without any follow-up, asserting that four weeks would suffice, even though I communicated that I was still experiencing issues. After about 12 or 13 days, I noticed a slight deterioration in my condition and opted to resume the medication. Before restarting, the largest rash measured approximately 2cm, while the rest were generally smaller than 1cm; initially, I had numerous rashes varying from 5cm to 2cm. This situation is causing me considerable anxiety to the extent that it’s affecting my sleep, mostly due to concerns about the potential side effects of prolonged terbinafine use. I’m eager to understand what the process should look like following a relapse. I have a couple of questions: 1. Would it be feasible to add an extra four weeks of treatment to build on the progress made previously? 2. Am I required to restart the entire regimen from the beginning, potentially extending it to at least six weeks since the initial four weeks proved insufficient?
