Interpreting High IgG Levels and Positive ANA: Should I Be Concerned About Cancer?
About a year ago, I experienced a severe health crisis involving Guillain-Barré syndrome and myocarditis, which ultimately resulted in heart failure and required ICU care. The medical team suspects an autoimmune issue, although no definitive autoimmune conditions have been diagnosed. Nonetheless, imaging tests like a PET scan have unveiled irregular activity in my bone marrow and the presence of a hemangioma on my spine. Recently, I consulted with an oncologist who reassured me that my normal CBC results indicate no immediate cause for alarm regarding cancer. However, I can’t help but wonder if the elevated IgG levels could hint at an underlying malignancy. As someone who has already faced heart failure and continues to grapple with unexplained health issues, the burden of medical bills has been overwhelming. Despite my efforts, I still feel far from my usual self. Essentially, I find myself questioning if I am at risk or living on borrowed time.

It's completely understandable to feel concerned about your health given your recent medical history and the complexity of your symptoms. Elevated IgG levels and a positive ANA (antinuclear antibody) can indicate autoimmune activity, but they do not directly point to cancer. Here’s a breakdown of what this might mean for you:
Key Points:
- Elevated IgG Levels: This can suggest an immune response, often seen in infections, autoimmune disorders, or chronic inflammation, but not specifically cancer.
- Positive ANA Test: This test screens for autoimmune disorders. While it raises suspicion for conditions like lupus or rheumatoid arthritis, it's not conclusive on its own.
- Normal CBC Results: Having normal complete blood count levels generally indicates that your bone marrow is producing blood cells adequately and is encouraging concerning immediate cancer concerns.
Explanation:
Given your history of Guillain-Barré syndrome and myocarditis, it’s understandable to be worried about your ongoing health. The elevated IgG and positive ANA can reflect an autoimmune process rather than malignancy. The oncologist’s reassurance, particularly with normal blood counts, is significant. It suggests that while monitoring is crucial, there's currently no evidence pointing towards cancer.
Next Steps:
-
Monitor Symptoms: Keep an eye on any new or worsening symptoms, such as fatigue, joint pain, or other changes in your health. Documenting these changes can be helpful for your healthcare providers.
-
Follow-Up: Schedule regular follow-ups with your healthcare team, including rheumatology and oncology, to keep track of your IgG levels and autoimmune markers.
-
Support Systems: Engage in supportive therapies like physical therapy or counseling to aid in recovery from your heart failure and improve your overall well-being.
-
Manage Stress: Given the burden of medical bills and your health concerns, practice stress-reduction techniques such as meditation, deep breathing, or gentle exercise, which can help improve both your mental and physical health.
-
Seek Financial Guidance: Explore resources such as financial assistance programs or community support services that may help alleviate the financial stress you’re experiencing due to medical costs.
It’s important to remember that you’re not alone in this, and taking proactive steps can help you navigate your health journey. If you have further concerns or if your symptoms evolve, reach out for help to discuss these specifically.

Understanding the Increased Pain in My Foot While Reclining
At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
