36F – Worrying Over “Low Antibody Area” on SPEP, Referred to Internal Medicine – Is This a Cause for Alarm?
Age: 37 years Height: 5 feet 8.5 inches Weight: 230 pounds Main issue: Anxiety regarding the “low antibody area” indicated on SPEP. Duration: Received lab results this month; symptoms have persisted for several years. Current health concerns: Undergoing evaluations for potential connective tissue or autoimmune disorders. Non-smoker, consumes alcohol minimally. Hello everyone, I am reaching out to gain some insights while I await my internal medicine appointment, which is scheduled three months from now. I am not seeking a diagnosis but rather wish to clarify whether my situation should be taken seriously. Here’s what I’m experiencing… I have struggled with persistent symptoms for the past five years, including chronic discomfort in my back and ribs, extreme fatigue, anemia, occasional shortness of breath, tingling sensations down my left shoulder, ongoing muscle tension, hair loss, facial rashes and flushing, dysautonomia, and more. I underwent a comprehensive evaluation by a rheumatologist, who found my ANA test to be negative and the ENA test results to be “below positive cutoff.” My inflammatory markers have been steadily increasing year after year, with my CRP at 33.5 and ESR at 45 during the latest checks. Recently, my rheumatologist discharged me and referred me to internal medicine after identifying a “possible low antibody region” on my SPEP, along with elevated beta 2 and C3 levels. Although there was no discernible m-spike, it was mentioned that 8% of monoclonal protein could potentially be undetected. The low antibody region comment was conveyed to me in a private message rather than prominently highlighted in the lab report I received. I was informed that further assessment is required, yet no additional details were given. I have not completed a 24-hour urine test, and I don't believe calcium levels have been checked recently. My kidney function appears normal based on blood work and urinalysis, with the only abnormal finding being the presence of crystals. I feel uneasy because my research indicates that low antibody regions in SPEP could be linked to plasma cell disorders; however, I've also learned that there are various other benign and autoimmune-related causes. The years of unclarified symptoms and scarce communication have made this uncertainty particularly daunting for me right now. Any thoughts or advice would be greatly appreciated!

It’s completely understandable to feel anxious about the results of your SPEP and the ongoing health concerns you’ve been facing. Let’s break this down and focus on the most important points regarding your situation and what steps you can take while you wait for your internal medicine appointment.
Main Points:
- Low Antibody Area on SPEP: This finding can indicate various conditions, some benign and others more serious. It may suggest issues related to immune function, but clarification is key.
- Persistent Symptoms: Your chronic symptoms and elevated inflammatory markers require careful monitoring.
- Next Steps for Clarity and Relief: While awaiting further evaluation, focus on managing symptoms and gathering relevant information.
Explanation:
A "low antibody area" in a serum protein electrophoresis (SPEP) test generally means there could be a decrease in specific immunoglobulins, which are proteins important for immune response. While such results can be linked to plasma cell disorders, they can also occur in benign conditions or in response to chronic inflammation or infections.
Your symptoms and elevated inflammatory markers (CRP and ESR) are concerning and warrant evaluation. The fact that you've been referred to internal medicine suggests that your healthcare team is taking this seriously. It's also good news that your kidney function appears normal, which is a positive sign.
Actionable Steps:
-
Symptom Monitoring: Keep a detailed journal of your symptoms, noting any changes, triggers, or patterns. This record can be useful for your upcoming consultations.
-
Complete Additional Tests: Schedule any follow-up tests recommended by your healthcare provider, such as the urine test for protein levels or checking calcium levels if you haven't already. These tests can provide critical information regarding your health status.
-
Focus on Self-Care: Prioritize good nutrition, regular gentle exercise (as tolerated), and stress-reducing activities such as mindfulness or yoga. These approaches may help alleviate some symptoms and improve your quality of life.
-
Reach Out for Support: Consider joining support groups for individuals with similar conditions, whether autoimmune or chronic pain syndromes. Sharing experiences and advice can be comforting.
-
Communicate with Your Healthcare Team: If your symptoms worsen or if you experience new symptoms (such as increasing shortness of breath, severe pain, or changes in your mental state), don’t hesitate to contact your healthcare provider for advice before your scheduled appointment.
Reassurance:
While it's natural to feel concerned given the uncertainties surrounding your health, remember that many conditions have effective management strategies. You are actively seeking care and taking steps to address your health, which is commendable. Remain patient and proactive as you navigate this process, and lean on trusted friends or family for additional support. If you have more questions or concerns, feel free to reach out.

Recurring Swollen Lymph Nodes and Itching After Consuming Certain Asian Cuisine
(Female, 29 years old, on contraceptives containing drospirenone and ethinyl estradiol, non-smoker, residing in Turkey, has endometriosis and iron deficiency anemia.) Hello everyone, I've been experiencing a peculiar reaction after enjoying specific Asian meals, such as malatang and Korean BBQ, and it happens quite regularly. Shortly after finishing these meals, I notice a stark itching sensation on my scalp and throughout my body. Although the itching subsides within a short period, it’s quite uncomfortable. A few hours later, I find that the lymph nodes on both sides of my neck become swollen and painful. They feel tender to the touch but aren’t hard or fixed, and the swelling generally diminishes with time. Thankfully, I haven’t experienced any tightness in my throat or difficulties with breathing, nor have I noticed swelling of the lips or tongue. Interestingly, I can consume soy sauce, peanuts, and kimchi by themselves without any adverse reactions. The troublesome symptoms seem to occur specifically when I eat dishes that have combinations including spicy broths, fermented sauces, shiitake mushrooms, and extensively seasoned or marinated items. This pattern has repeated itself on several occasions, exclusively with these types of meals. In your opinion, does this suggest a case of histamine intolerance or mast cell activation rather than a traditional IgE-driven allergy? Additionally, has anyone else encountered reactive cervical lymph node swelling in similar circumstances? I’m contemplating whether to pursue allergy testing or to first implement some dietary changes. The swelling of my lymph nodes does concern me a bit. I would greatly appreciate any thoughts or insights you might have!
Concerns About a Persistent Cord-Like Structure in Elbow After Overexertion
Hello everyone, I'm a 24-year-old male, and there's something on my mind that I'd really like to discuss. Approximately two months back, I overexerted myself while performing bicep curls with a resistance band. I pushed too hard and the following day, I experienced debilitating muscle soreness in both arms, reminiscent of intense delayed onset muscle soreness (DOMS). This discomfort persisted for about a week. To manage the pain, I used topical pain-relief gel, and gradually, the soreness subsided. After that period, I regained full range of motion in my arms with no limitations. However, roughly a day following that intense workout, I discovered an unusual change in my left arm (the right arm remains unaffected). There appears to be a cord-like structure located in the inner part of the elbow crease, specifically on the thumb side. This structure begins roughly 1.5 inches above the elbow crease and extends about an inch below it. It feels firm, similar to how a tendon would feel, and while it shifts a little when I move my fingers or forearm, its overall shape remains consistent. Here are some notable points regarding my condition: - There is no pain at all now. - I do not experience any weakness or loss of motion. - I haven’t had any sensations of tingling or numbness. - The size of this structure seems to have diminished somewhat since I first noticed it. - My right arm is functioning perfectly. - I've refrained from exercising since that time. I visited a healthcare provider who examined the area and recommended anti-inflammatory medication along with vitamin E, assuring me that there was no significant cause for concern. Nonetheless, it has been nearly two months since this incident (which occurred in mid-November), and this cord-like structure continues to exist, prompting me to question whether this is a standard part of the healing process or if it is something that typically requires a longer duration to resolve. I would greatly appreciate your insights: - Is it common for such changes to persist for several months? - When might it be safe for me to return to my strength training regimen?
Persistent Discomfort at the Back of the Head and Neck: Seeking Advice
Greetings! For the past year, I have been experiencing an ongoing discomfort characterized by a sensation of pressure at the rear of my head and neck. This condition has led to several accompanying symptoms, including cognitive fog, significant fatigue, intermittent balance issues (though I've not yet fallen), occasional blurred vision, among others. I underwent both a CT scan and an MRI of my brain; however, the results did not reveal any abnormalities. An x-ray of my neck indicated a slight straightening of the cervical curvature, which was minimal. In response, I engaged in physical therapy and performed postural exercises. My blood tests showed normal results, and an examination by an ophthalmologist indicated no issues with my eyes. A neurologist suggested that my symptoms might be due to muscular cervicalgia, but despite trying medication, I have not found relief. I have explored numerous medications in pursuit of alleviating these symptoms. I am truly desperate for assistance as I feel like I'm losing control and the quality of my life is diminishing.
Concerns Regarding Cardiac Procedure and Medication Denial
Subject Details: - Age: 44 - Gender: Male - Height: 5 feet 11 inches - Weight: 240 pounds - Ethnicity: Caucasian - Duration of Symptoms: Ongoing - Location: New York - Pre-existing Medical Conditions: Kidney failure, Stenosis of the Left Anterior Descending (LAD) artery - Current Medication: Norvasc 10mg I am set to undergo a cardiac catheterization tomorrow. Unfortunately, my physician has denied me pain relief, insisting on prescribing NSAIDs and Tylenol even though I have documented allergies to these medications. Instead of acknowledging my discomfort, he implies that I may be seeking drugs. To clarify, I am not, nor have I ever been, involved in drug-seeking behavior, and it is deeply distressing to be treated in this manner. Moreover, the doctor stated that it’s against the law to insert a stent if the blockage is below 70%. I’m seeking clarification on this policy. His demeanor was quite abrasive, yet given his position as the head of the cardiology unit, I feel powerless to address this behavior. When I inquired about his reasoning, he ominously suggested that he might cancel my procedure, which is critical for assessing the severity of my LAD stenosis. I would greatly appreciate any support or advice regarding this situation. Thank you for taking the time to read my concerns.
Relieving the Sensation of a Lump in the Throat and Persistent Cough After a Cold
At 26 years old, I've recently faced a bout of illness that spanned from January 25 until around February 2. Initially, it was a severe sore throat, followed by a runny nose and then a feeling of congestion. After a brief period of feeling better, I encountered another setback. On February 10, I experienced another intense sore throat lasting three days, which evolved into an annoying sensation of a lump in my throat, accompanied by a persistent dry cough. This situation is frustrating. I’m unsure about visiting Urgent Care, as it seems excessive, yet I find myself limited to just tea and water for relief. The sensation in my throat feels centralized, and today I decided to start taking Mucinex, planning to continue with it for a day or two to see if it alleviates my symptoms. I wonder if this lump in my throat might stem from irritation caused by the dry cough. Finding a method to quell this dry cough feels challenging. Also worth noting, I am not taking any other medications at the moment. Interestingly, I've never been ill right after recovering from a cold before; this feels like an unusual situation. I suspect that my lack of proper nutrition during my cold might have compromised my immune system, contributing to this recurrence.
