Understanding My Extra Lumbar Vertebra: Nerve Distribution and Possible Implications
Upon undergoing an MRI, I learned unexpectedly that I possess a sixth lumbar vertebra. This finding is entirely typical and hasn’t led to any noticeable complications for me. My curiosity lies in whether having this extra vertebra means there are more nerves emanating from my spinal cord in that segment of my spine compared to individuals who don't have an L6. Could it be that the quantity of spinal nerves remains relatively constant, simply spread out more evenly in my case? Additionally, I’m intrigued about whether this additional vertebra could be linked to some conditions I face, such as irritable bowel syndrome (IBS) and complex regional pain syndrome (CRPS) affecting my lower leg. Is this situation similar to individuals born with extra digits, where the body naturally accommodates and integrates the additional structures in a typical manner?

You have an interesting situation with your sixth lumbar vertebra (L6) that, while not uncommon, raises valid questions about nerve distribution and potential implications for your health concerns like irritable bowel syndrome (IBS) and complex regional pain syndrome (CRPS).
Summary of Key Points:
- Nerve Distribution: Generally, the number of spinal nerves doesn't increase with the addition of a lumbar vertebra; instead, the existing nerves may spread out slightly differently.
- Link to Conditions: While there isn't a direct link between having an extra lumbar vertebra and conditions like IBS or CRPS, anatomical variations can sometimes influence nerve-related symptoms.
- Body Adaptation: Like individuals born with extra digits, the body can accommodate structural differences such as an additional vertebra, often without functional complications.
Explanation:
The human spine typically has five lumbar vertebrae (L1-L5). Having a sixth lumbar vertebra (L6) is known as lumbarization and usually imposes no significant issues. While more vertebrae can suggest a change in structure, the associated spinal nerves remain structurally constant and primarily serve the same regions of the body. This configuration can lead to variations in nerve signal distribution rather than an increase in the number of nerves.
As for your conditions (IBS and CRPS), research has not established a direct causative relationship between an extra lumbar vertebra and these syndromes. IBS is primarily related to gastrointestinal function, and CRPS often involves a different mechanism of chronic pain. However, variations in spinal anatomy may indirectly affect how nerves function or transmit pain signals, leading to different symptom experiences.
Next Steps:
-
Monitor Symptoms: Keep a symptom diary for both IBS and CRPS, noting any changes or patterns in your pain or gastrointestinal distress. This can help identify triggers or correlations over time.
-
Educate Yourself: Understanding your conditions better can empower you to manage them. Look into reputable resources regarding IBS and CRPS.
-
Self-Care Practices: Implement stress management techniques such as yoga or mindfulness, which can benefit both abdominal and pain-related conditions.
-
Stay Active: Gentle physical activity may also aid in managing symptoms and promoting overall spinal health. Focus on low-impact exercises tailored to your comfort.
If you wish to explore a deeper connection between your structural anatomy and your health conditions, consider discussing your thoughts with a healthcare professional who specializes in pain management or spinal health, as they can provide personalized insights.

Is Wet Cupping Effective for Post-Accutane Symptoms?
Hello everyone, I’m a 25-year-old woman, measuring approximately 152 cm tall (around 5 feet) and weighing about 40 kg (88 lbs). Earlier this year, I underwent treatment with Accutane (Isotretinoin) for several months to address moderate acne. My initial dose was set at 20mg, which was later raised to 40mg. I completed my course about four months prior. While my skin condition has seen significant improvement and my blood work indicates normal levels, I continue to experience a few persistent side effects: - Discomfort in my muscles and bones - Daily fatigue - Fluctuations in mood or emotional instability Recently, I came across the concept of Hijama, or wet cupping therapy, and I became intrigued. I've heard that this treatment might assist in "detoxifying" the body and enhancing blood flow, which could potentially alleviate some of the residual effects from medications like Accutane. Thus, I have a couple of questions: - Has anyone here attempted Hijama after completing their Accutane treatment? - Did you find it beneficial for symptoms such as body soreness, fatigue, or emotional distress? - I would appreciate hearing any insights or shared experiences you might have. Even if scientific validation is lacking, I'm eager to learn about the outcomes for others. Thank you all in advance for your input! 🙏
Recovering from the Flu and Experiencing Excruciating Facial Pain
At 19 years old, I battled a significant illness for around five days. After starting to recover, I ventured out to the state fair, but the following morning, I felt utterly incapacitated. A visit to urgent care confirmed that I had the flu. Fortunately, that severe discomfort lasted only for one day. Now, four days later, I find myself grappling with overwhelming congestion and a sharp pain concentrated on one side of my face. Additionally, the same side experiences considerable jaw soreness, making it difficult for me to open my mouth. I have a history of grinding my teeth at night and have experienced minor jaw problems before, but this level of pain is unprecedented. Neither Tylenol nor Advil seems to alleviate my suffering. On top of that, my eyes are consistently crusty—similar to pink eye symptoms, yet without the actual condition. They leak excessively, and I wake up to find them stuck shut. These unusual symptoms have heightened my anxiety regarding my health. Given my tendency to develop sinus infections, I wonder if I might now be dealing with an unusual case of one.
Persistent Pain on the Right Side of Abdomen and Back
I’m a 32-year-old female weighing around 230 pounds and standing 5 feet 1 inch tall. My current medications include Vyvanse, Buspirone, guanfacine, and hydroxyzine to manage ADHD and anxiety, along with metformin for polycystic ovary syndrome (PCOS), omeprazole for gastroesophageal reflux disease (GERD), and a multivitamin along with inositol supplements. Recently, I underwent a bilateral salpingectomy in November 2024 and had my gallbladder removed just a month ago; however, the pain I’m experiencing predates the gallbladder surgery. I find myself in a frustrating situation, particularly because my surgeon declined to perform any scans prior to the gallbladder removal, insisting that my discomfort was entirely related to my gallbladder. For the past six months, I have been suffering from persistent pain located somewhere on the right side of my abdomen and/or back. I emphasize *somewhere* due to the fact that the pain seems to shift with my movements and does not follow a predictable pattern. Currently, the discomfort is centered in my mid-abdomen, near my lower ribs, but not long ago, it was around my hip area. Even now, as I type, sitting up straight has caused the pain to transition from my abdomen to my back, precisely in that same region. Massage therapy provides some temporary relief; the pain feels dull and achy, and I have that sensation that it yearns to be massaged. Unfortunately, standard pain relief medications have little effect. After my gallbladder surgery, the pain seemed to diminish briefly, likely masked by the more intense post-operative discomfort, but it returned within a week, persistent as ever. In addition to the pain, I’ve experienced intermittent nausea (which is usually linked to my anxiety) and severe diarrhea that began after the gallbladder removal. According to my surgeon, my gallbladder was indeed very inflamed and full of stones, affirming its necessity for removal despite any uncertainty it may have contributed to my pain. He also mentioned that it was adhered to my abdominal wall, which raises questions about possible relevance. Unfortunately, shortly after my surgery, my doctor stopped accepting my insurance, which has hindered my ability to secure follow-up appointments or discuss my ongoing pain with him. I am currently attempting to find a new physician, but there are limited options available at the moment.
Concerns Over My Friend's Spinal Cyst
My friend, a 25-year-old woman, recently learned she has a sizable cyst near her spine. The physician informed her only that the cyst is "large" and poses severe risks, such as the potential to cause paralysis or even be life-threatening if it ruptures. However, the doctor did not recommend surgery, citing the operation as risky with a possibility of recurrence. This particular healthcare provider has often been somewhat indifferent towards her, which worries me, especially given her keen intelligence. I am left questioning the level of danger she may actually face and whether she should seek further evaluations or other medical opinions. My friend meets nearly all the criteria indicative of Ehlers-Danlos Syndrome (EDS), although I'm uncertain how that condition might influence her situation.
Concerns About Recent Symptoms
Greetings! I'm a 27-year-old female with a four-year-old child. I have been diagnosed with hyperthyroidism, yet I am not currently on any treatment due to a lack of health insurance. This has also prevented me from seeing a doctor for several years. Although I have researched possible causes, including Graves' disease, lupus, and thyroiditis, I'm uncertain about what specifically might be affecting me. In conjunction with my thyroid issues, past lab work indicated elevated bilirubin levels, and there was mention of a mass in my abdomen, though I can't remember the details as it was several years ago and shortly after that, my insurance coverage lapsed. I tend to consume alcohol heavily and had previously used tobacco, specifically vape pens, but am attempting to quit. Lately, I've experienced a noticeable pulsing sensation in my abdomen. While I didn’t think much about it at first, it has become more pronounced when lying down, prompting me to examine my abdomen. In doing so, I believe I can detect a lump, though I'm not entirely sure if it’s actually there. This has led me to wonder about whether I should be anxious regarding these symptoms. Do you think my concerns are unfounded, or do they warrant genuine attention? If so, what might this indicate? Thanks for any insights you can provide!
