Understanding Persistent High SED Rate Amidst Normal Blood Tests
I’m a 28-year-old female, standing at 5 feet 5 inches tall and weighing 160 pounds. I maintain an active lifestyle by exercising regularly, including activities like walking, jogging, weight training, and yoga. Additionally, my diet consists primarily of whole plant-based foods. For my fibromyalgia, I’m currently using vitamin D supplements, probiotics, and Cymbalta. Due to a range of connected health concerns such as acid reflux, migraines, fibromyalgia, joint discomfort, and pain in my glands and tonsils, I have undergone numerous medical evaluations. Back in December, my SED rate was measured at 31. After a follow-up test last week, it remains elevated at 25. In contrast, my CRP levels have consistently been normal, as has the complete blood work I completed in December. I do not have anemia, and the only notable abnormality surfaced during testing was a DNA (DS) antibody level of 5, which places me in the indeterminate category regarding lupus. However, following this latest SED evaluation, I underwent extensive autoimmune testing, all of which returned negative or within normal ranges. I also conducted a thyroid function test in December, and while the results were satisfactory overall, my TSH level was on the low side at 0.6. What could be the underlying reason for my elevated SED rate, especially considering that many typical diagnoses appear to have been excluded?

Main Point: Your elevated SED rate, despite normal blood tests for autoimmune conditions, suggests ongoing inflammation or other underlying issues, which might not be fully diagnosed yet.
Explanation: The erythrocyte sedimentation rate (SED rate) is a blood test that can indicate inflammation in your body, but it doesn't specify where the inflammation is coming from or its exact cause. An elevated SED rate can be influenced by several factors, including chronic conditions like fibromyalgia, infections, or even emotional stress, and in some cases, it can remain elevated without a clear diagnosis. Since your other blood tests, including CRP levels and autoimmune markers, are normal, this means that serious conditions like lupus or other autoimmune diseases are less likely.
Your active lifestyle and whole food plant-based diet are positive factors for overall health, but they may not eliminate all sources of inflammation. It’s also important to consider that factors such as hormonal changes, environmental exposures, or even stress could contribute.
Next Steps:
-
Monitor Symptoms: Keep a daily diary of symptoms related to your overall health, focusing on when you experience changes in pain, fatigue, or other discomforts.
-
Evaluate Lifestyle Factors: Consider the impact of stress and rest. Stress management techniques, such as mindfulness or relaxation exercises, could help. Ensure you are getting adequate rest and sleep, as fatigue can contribute to your condition.
-
Anti-inflammatory Strategies: Although you are eating a plant-based diet, assess your current food choices for any inflammatory foods (like processed foods or high sugar intake) and ensure to include anti-inflammatory foods (like fatty fish, leafy greens, nuts, and turmeric).
-
Follow Up on Low TSH Levels: Since your TSH is on the lower side, consider discussing this with a healthcare provider to rule out hyperthyroidism or other thyroid-related issues.
-
Stay Connected with Healthcare: Continue to communicate with your healthcare provider about your SED rate and any evolving symptoms to stay proactive about your health.
If your condition changes, symptoms worsen, or new symptoms develop, consider seeking further evaluation. Additionally, let me know if you’d like information on specific lifestyle changes or wellness practices!

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!
Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
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.
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
