Bilateral Finger Numbness
A 46-year-old male, who smokes, weighs 77 kg and stands at 6 feet tall, consumes beer occasionally and has a diagnosis of ADHD. His current medications include Elvanse at 70mg, pregabalin at 600mg, and venlafaxine at 150mg. In the past year, he underwent a series of extensive tests for fatigue, which included assessments for B12 levels, iron, glucose, and vitamin D. These led to the use of a CPAP machine. For more than a year, he has experienced mild numbness in his fingers. Recently, he took up a cleaning job, and in the last three months, he has noticed that the numbness in his right hand has intensified, affecting his thumb, index, and middle fingers. Meanwhile, his left hand shows significant numbness in the ring and middle fingers, which paradoxically have areas of heightened sensitivity—any slight impact or pressure causes noticeable pain. He struggles increasingly with hand functionality, often dropping items and finding it difficult to perform tasks such as opening jars or fastening buttons. There is also a notable weakness in his non-dominant left hand. Initially, he suspected that these symptoms were related to carpal tunnel syndrome but now questions the likelihood of both hands exhibiting similar issues, especially with the left one deteriorating more rapidly over a short span of three months. With an appointment scheduled with his general practitioner on September 3rd, he is contemplating whether he should seek another opinion sooner. Thank you for any insights you can provide.

Bilateral finger numbness, particularly with the combination of increased symptoms and functional impairment, raises important concerns. Given your history of numbness, recent exacerbation, and the complexity of your symptoms, it’s essential to address these issues thoughtfully.
Explanation: Numbness and weakness in the hands can have various causes, including nerve compression (like carpal tunnel syndrome), peripheral neuropathy (possibly related to your medications or other underlying conditions), or vascular issues. The nature and distribution of your symptoms—specifically the numbness and sensitivity on the left hand—suggest a possibility of increased neurological involvement that may not be solely attributable to carpal tunnel syndrome.
Your recent job involving cleaning could have contributed to more repetitive hand movements, which may lead to exacerbated symptoms. Additionally, smoking and the medications you’re on may play a role in peripheral nerve health.
Next Steps:
-
Symptom Diary: Start keeping a detailed record of your symptoms—note when numbness occurs, any activities that worsen it, and any other associated symptoms (like pain or weakness). This can help your doctor understand what's happening.
-
Ergonomic Adjustments: Since your cleaning job may require repetitive movements, consider modifying how you grip tools or perform tasks. Use ergonomic grips, take frequent breaks, and allow your hands to rest whenever possible.
-
Limit Irritants: Avoid smoking further, as it can negatively impact circulation and nerve health. Additionally, consider reducing alcohol intake as it might also contribute to nerve issues.
-
Stay Hydrated and Nourished: Proper nutrition and hydration can support nerve health. Ensure you’re getting a balanced diet rich in vitamins, particularly B vitamins, to support nerve health.
-
Evaluate Medications: Some of your current medications, including pregabalin and venlafaxine, can have side effects that might contribute to numbness. Once you see your general practitioner, discuss whether these medications might be impacting your symptoms or if alternative options are available.
-
Consider Seeking a Neurologist Consultation: Given the specific concerns about the bilateral nature and recent changes in your symptoms, you may want to consider having a consultation with a neurologist. This professional can conduct specialized tests to assess for any underlying neurological causes ahead of your scheduled appointment.
It's understandable to feel concerned, especially with the impact on daily activities. Tracking your symptoms will give you valuable insights and bolster your discussions with healthcare providers. Prioritize these steps while you await your appointment, and feel free to reach out for additional advice or clarification on any of these points.

Concern for My Health: Seeking Answers
As a 37-year-old male who smokes and has a history of bipolar disorder (BPD) and memory problems, I’ve recently faced some alarming health issues. Initially, I felt fine, but a few months ago, my condition took a sharp turn. I began experiencing debilitating headaches, neck pain, and an unsettling stiffness throughout my body. I also noticed an uncomfortable sensation where my skin felt like it was burning, as well as issues like oral thrush and mouth ulcers. Cognitive challenges surfaced, including brain fog and confusion. I felt emotionally detached, and my genital area became painful to the touch. Additionally, I experienced soreness in my legs and arms, making it difficult to climb stairs. Alongside these symptoms, I was suffering from night sweats and had trouble sleeping. Most concerning was a sudden flare-up in my genital region. My doctors suggested that it was herpes, a condition I’ve dealt with for years. Thus far, I have undergone significant medical evaluations: I spent three days in the hospital due to intense headaches, where I had extensive blood tests, a CT scan, and a lumbar puncture. I visited a sexual health clinic two weeks prior and had to wait for a retest because my initial blood work fell outside the relevant timing. Fortunately, during my hospital stay, all tests returned negative and my results were normal, which leaves me more confused. Despite these clear test results, I feel like I'm falling apart and struggling to maintain my sanity. I’m reaching out for any insights or ideas that might help illuminate what I might be experiencing. Thank you for your time and assistance.
Experiencing Lip Numbness Following General Anesthesia
At 29 years old, I've recently undergone a surgical procedure on my head, and now I've noticed that only part of my lower lip has become numb. After contacting the hospital ward, the doctor reassured me that this numbness is unlikely related to the surgery itself; it might instead stem from trauma caused by the intubation during the procedure. I’ve checked my lip thoroughly, and there's no visible skin damage or any noticeable changes—it's just a complete lack of sensation. The doctor advised me to visit the emergency department should my symptoms not improve, yet I’m uncertain if my situation truly qualifies as a medical emergency. Is experiencing this kind of numbness common following such procedures?
Persistent Unexplained Lesion on Inner Thigh
At 24 years of age and female, I have been dealing with what appears to be a minor blood blister located on the inner part of my lower thigh for approximately four to five years. This lesion tends to appear and disappear over time. Occasionally, it resembles an empty blister, only to later expand slightly and appear filled with a dark liquid. When it reaches its largest size, it is comparable to a Tic Tac and has a slight elevation. Although it does not cause any pain, I can feel its presence as I walk, particularly when my thighs come into contact with one another. Furthermore, I wish to note that recently there has been the first instance of some redness surrounding the area. I will provide additional details in the comments.
