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.

Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.

There is no report of pain, but the patient experiences mild hoarseness. What might be the diagnosis?
Post-Gallbladder Surgery Concerns: Potential Infection Three Weeks Later?
Subject's Age: 35 Gender: Female Height: 5 feet 4 inches Weight: 160 pounds Ethnicity: Asian Duration of Symptoms: Last Three Weeks Geographic Location: United States Relevant Medical History: Almost three weeks ago, I underwent gallbladder removal surgery. In the last few days, I have observed a small amount of cloudy discharge emerging from my incision site. Recently, I noticed what appears to be pus leaking from the area. While there is no significant pain, I do feel a mild soreness when I touch or move the site. I have not experienced any fever or chills, and there’s no unpleasant odor coming from the wound. Should I continue to clean the area with soap and water, or is it advisable to seek medical attention at the emergency room for further evaluation?
Understanding My Experiences with Dissociation and Physical Symptoms
Hello everyone! I'm 15 years old and I’ve been grappling with intense feelings of dissociation recently. About two years back, I experienced what I now refer to as a "silent seizure" for the first time. It happened around 2 PM while I was at school in the band hall. Suddenly, I found myself zoning out completely; I was just sitting there, disassociated from reality, until it dawned on me that I couldn’t seem to reconnect with my surroundings. Feeling lost, I turned to a friend and anxiously asked, "Where am I?" She chuckled, unaware of the seriousness of my situation, but I stood up and wandered out of the classroom, aimlessly walking towards the bathrooms. The sensation was akin to being in a dream—you know you’re somewhere, yet you can’t fully engage with the moment for what felt like 5 to 10 minutes. Strangely, I even had the feeling of observing myself from above as I moved through the halls, like a scene from a dream. In a state of panic, I contacted my mom. By the time I managed to leave school, my mind was clearing. She took me to her workplace where a colleague checked my blood sugar levels, revealing it was low. I had eaten that day, so this was unexpected (especially since my mother also faces issues with low blood sugar). This occurrence was unprecedented for me; thankfully, I haven’t faced such low levels since then. In the following weeks, I experienced intermittent dissociative episodes, prompting me to visit a doctor. I underwent blood tests, an electrocardiogram (EKG), and a routine examination. Everything appeared normal, except I was diagnosed with anemia—something my mother and sister also deal with. I walked away from that appointment without any real explanations, and after a while, the episodes subsided—thankfully, a relief. FAST FORWARD TO NOW: (15 years old) (Potentially relevant context) Recently, I’ve been enduring severe heart and chest discomfort. I’ve been noticing irregular heartbeats, sporadic strong pulsations, and sharp pain localized in my heart region and upper right chest. Lying on my side can be quite painful, and sometimes I struggle to take deep breaths. I make it a priority to get a full eight hours of sleep each night, I take daily vitamins, and I’m actively involved in competitive cheerleading, maintaining a healthy fitness level for my height and weight. We sought medical advice again, underwent numerous tests, and, once more, everything checked out fine. My heart was deemed healthy, and all other measurements were satisfactory. Initially, we suspected anxiety might be a factor, but my mom is hesitant to consider antidepressants, believing that my age may limit treatment options. She has recommended that I hydrate more and practice breathing exercises (which is somewhat ironic since I struggle to breathe when these pains occur, yet I don’t argue). UPDATE: During practice today, I unexpectedly experienced my first "silent seizure" episode in two years. It was more disconcerting than I recalled. I lost track of my location again and couldn’t re-engage with reality. It felt as if I was observing those around me from a dream-like vantage point. This realization frightened me, thinking that I had moved past these episodes. It took about ten minutes for me to regain my awareness of my environment. Additionally, this week, I noticed moments of dissociation, albeit not as intense as previous episodes. I found myself vacantly staring, and my vision felt oddly lazy, frequently. It's worth noting that I do not have a lazy eye. I plan to document these occurrences meticulously, and if they persist, I will consult my doctor again. Meanwhile, if anyone has suggestions about what might be happening to me, I would greatly appreciate it. Is this potentially linked to anxiety? I’m genuinely confused about my condition!
Identifying a Mysterious Brown Circle on My Scalp
Age: 21 Gender: Female Height: 5'4" Weight: 175 lbs Ethnicity: White (Scottish/Irish) Location: California Current Medication: Testosterone injection administered subcutaneously in the thigh While I was having my hair dyed blue, my girlfriend noticed a perfectly circular brown mark on my scalp. It resembles a circle that appears to have been made with a brown marker. The size of the ring is similar to my thumb’s tip and contrasts sharply with the lighter shade of my scalp. There is no evidence of hair thinning or loss around this circle; we only discovered it because we were parting my hair. I’m curious if this could be connected to the brain fog or headaches I’ve been experiencing lately. I looked online, and while ringworm was suggested, it doesn’t match my symptoms since there are no bald patches or flaky skin. I’m open to answering any additional questions to help clarify this situation, as it's causing me some concern.
