Concerns Over B12 Levels and Nerve Sensations: Seeking Guidance
Greetings! I’m a 27-year-old female diagnosed with ADHD five years ago through a neuropsychologist. In addition to ADHD, I deal with generalized anxiety disorder and currently take Vyvanse and Inderal for my symptoms. For the past decade, I have also been experiencing IBS-D; initially, my gastroenterologist suspected Crohn’s disease due to inflammation noted in my intestinal MRI. However, after undergoing a pill endoscopy, he confirmed that the results were normal and attributed my issues to IBS. Interestingly, I was on Crohn’s medication for a period between the MRI and the endoscopy. Around a year ago, I approached my doctor regarding concerning symptoms, including numbness in my little toes, tingling sensations across my face and jaw, persistent burning sensations in my lips, and blurred vision—even though my optometrist has assured me that my sight remains unchanged. An MRI of my brain has yielded normal results. Currently, my B12 level is at 176, which meets the lower threshold defined by my hospital. Eight years ago, it stood at 220. My physician maintains that my B12 level falls within normal limits and is not responsible for the tingling in my extremities. He further suggested that my IBS is not likely the culprit either, despite my meat consumption. Is it advisable for me to seek a second opinion? I am genuinely concerned about the possibility of enduring nerve damage. Even though my B12 levels are classified as normal, could they still contribute to my symptoms? My doctor seems to attribute everything to my anxiety. Any insights or advice would be greatly appreciated.

It sounds like you are experiencing a complex set of symptoms that are concerning to you, especially related to your B12 levels and nerve sensations. The overlap of ADHD, anxiety, and gastrointestinal issues, along with your neurological symptoms, can be challenging to navigate. Let's break this down clearly.
Key Points
- B12 Levels and Symptoms: Your B12 level is on the lower end of normal, which can potentially contribute to neurological symptoms like numbness and tingling.
- Nerve Sensations: Tingling, burning, and numbness in extremities can be associated with various issues, including vitamin deficiencies, anxiety, or other neurological conditions.
- Second Opinion: Seeking a second opinion can be valuable, especially if you feel your current healthcare provider isn't addressing your concerns adequately.
Explanation
Vitamin B12 is essential for nerve health, and levels below optimal can lead to neurological symptoms, even if they are still classified as "normal" based on typical lab standards. The symptoms you're experiencing—like tingling and burning—could potentially be related to B12 deficiency or another underlying condition not yet diagnosed.
Your history with anxiety and IBS also complicates things, as these can sometimes mimic or coexist with neurological symptoms. It's crucial to differentiate between issues related to anxiety and those stemming from a physical condition.
Next Steps
-
Consider Dietary Sources: Focus on increasing B12 intake through foods such as meat, fish, dairy, and fortified cereals. If you're vegetarian or vegan, consider fortified foods or supplements.
-
Vitamin B12 Supplementation: You might benefit from B12 supplementation, even if your levels are within the lower normal range. Discuss this option, including the dosage, with another healthcare professional.
-
Symptom Diary: Keep a detailed diary of your symptoms, including when they occur, their intensity, and any triggers. This record will be helpful if you consult another doctor.
-
Second Opinion: Seek a second opinion from a neurologist or a physician specialized in nutrition or gastrointestinal health. Ensure the new doctor reviews all relevant examinations, particularly your vitamin levels and neurological symptoms.
-
Manage Anxiety: Continue managing your anxiety with your current treatment, as untreated anxiety can exacerbate physical sensations. Consider discussing with your mental health provider if adjustments might be beneficial.
Your ongoing concerns about possible nerve damage are valid, and addressing your symptoms comprehensively is essential. You have the right to advocate for your health and seek out the answers you need. Let me know if you have any further questions or need additional information!

17-Year-Old Female Experiencing Chronic Acne Scarring on Back and Arms Despite Prescription Remedies
Age: 17 Gender: Female Country of residence: United Kingdom Skin type: Dark / Black Medical background: No significant health issues Medications: Previously utilized azelaic acid and benzoyl peroxide Timeframe: Many months to years following acne resolution Greetings, I am a 17-year-old girl dealing with long-lasting scars on my back and upper arms from acne, which have not improved even after following prescribed treatments. In the past, I experienced acne primarily on my upper back, shoulders, and arms. While the active breakouts have largely ceased, I am left with noticeable dark spots and irregular skin texture. The scars I have include: • Dark brown hyperpigmentation • Certain areas appear slightly sunken • Uneven or coarse surface • No raised or keloid scars present My GP prescribed azelaic acid and benzoyl peroxide, which I applied regularly. Unfortunately, the azelaic acid did not significantly lighten the scars and seemed inadequate for the pigmentation level. Although benzoyl peroxide was effective against my active acne, it did not enhance the appearance of the scarring. The marks have been present for a considerable time and are quite stark against my skin tone. I do my best to avoid picking at my skin and maintain proper hygiene, yet the scars aren’t diminishing on their own, which is negatively impacting my self-esteem—especially when I wear sleeveless or backless outfits. Currently, I'm exploring the possibility of using retinoids like adapalene or tretinoin. However, I’m uncertain if these would be suitable or effective for treating scarring on my back and arms, particularly with my darker skin type. I would like guidance on the following questions: • Does this seem to be primarily post-inflammatory hyperpigmentation, atrophic acne scars, or possibly a combination of both? • Is azelaic acid effective for this type of scarring, or are more potent treatments generally required? • Are topical retinoids such as adapalene or tretinoin advisable for this sort of scarring? • What treatments are typically recommended for acne scars on the back and arms in individuals with darker skin tones? • Should I insist on a referral to a dermatologist, or is it better to attempt specific topical therapies first? Any insights or recommendations you could offer would be greatly appreciated.
Persistent Itching and Burning Around Neck and Scalp - Should I Keep Using Cephalexin?
Greetings, I’m a 35-year-old female. I recently developed a rash that began on the back of my neck and subsequently spread to my ears. After consulting with my physician, I was prescribed ketoconazole shampoo to address a suspected fungal rash. Despite using it diligently for four days, the condition actually aggravated, affecting my ears, the back of my neck, and my scalp more significantly. Seeking further assistance, I visited an urgent care facility where the medical staff suggested that I might be experiencing bacterial folliculitis. As a result, they prescribed cephalexin, which I am to take at a dosage of 500mg three times daily for a week. I took my first dose yesterday, yet the intense itching and burning sensations persist without improvement. Is it advisable for me to continue the medication? How long does it typically take to see improvement? Is it common to experience these symptoms alongside bacterial folliculitis? I appreciate your time and any guidance you can provide on this matter!
Concerns About Hearing Loss After Extended Earphone Use
For the past two and a half years, I have primarily relied on in-ear earphones, with the right one typically experiencing less usage—mostly for short videos or brief instances. Recently, during a singing session, I noticed something unusual. I covered one ear to monitor my pitch, and I was surprised to find that my hearing felt unclear and somewhat muffled. This was an experience I hadn’t recognized before. After conducting a few tests by alternately covering each ear, I discovered that my left ear can hear clearly and accurately, while my right ear perceives sounds as muffled, as if there’s a barrier in front of the speaker. I’m seeking advice as a 17-year-old student from Pune, India, with financial constraints that prevent me from adding stress to my parents. I’m deeply concerned whether this issue could be permanent, and if there’s any possibility of recovery. Although I can still hear sounds from my right ear when they are very close, I am unsure of the next steps. I have made the decision to discontinue using earphones starting today, but I’m wondering what additional measures I should take. Would it be advisable to pursue an audiometry test or consult an audiologist for a professional evaluation?
Dealing with Possible Epididymitis
A male, aged 40, standing at 5'9" and weighing 10.5 stone, presents a health concern. He has a history of smoking but refrains from alcohol consumption. For several years, I've grappled with a weakened bladder. However, over the last year or two, I've been experiencing intense discomfort in my right testicle. Initially, I thought I discerned a lump, prompting me to reach out to a physician. Unfortunately, the advice I received was limited; the doctor recommended an STI screening without conducting any examinations. I complied with the test, which returned negative results. Although the pain subsided briefly, it has now returned with greater intensity. I have undergone blood tests focusing on kidney, bladder, and prostate functions, all of which yielded normal results. Now, the medical team is leaning towards a diagnosis of epididymitis. The pain is excruciating and difficult to endure. I’ve scheduled an appointment for a prostate and testicular examination, which may lead to an ultrasound scan or possibly a urethral procedure to eliminate any serious underlying issues. The thought of the forthcoming examination fills me with anxiety, as I'm certain it will be painful. I'm curious if anyone has experienced epididymitis and what outcomes you faced, including any surgical interventions that may have been necessary.
Concerns Regarding Neck Pain After Lifting Incident
I’m a 27-year-old man, standing at 174 cm and weighing 63 kg, residing in Australia. Earlier today, I attempted to lift a heavy case using only one hand. Unfortunately, I didn't realize it was unlatched, and when it opened unexpectedly, I felt significant stress in my lower neck and upper shoulder area. Approximately four hours later, I began to experience a pulsating discomfort on the left side of my neck, extending from beneath my ear down towards my collarbone. I have a medical background of neurological issues related to my vision, along with episodes of facial drooping that are currently under investigation. After the initial neck discomfort (which subsided quickly), I noticed a resurgence of blurriness in my vision. Could this incident have caused an injury to my neck that might be aggravating my neurological symptoms? Is there a chance that this situation could be a vascular emergency?
