Chronic Elevated CRP Levels with Normal ESR: Investigating Possible Pericarditis
Hello everyone, I’m reaching out to see if anyone has gone through similar health concerns or can shed some light on my situation. To provide some background, I am a 25-year-old woman who has been under the care of a rheumatologist for several years. My medical history includes a positive ANA test and ongoing elevated CRP levels, yet all additional autoimmune tests have returned negative results. Notably, my ESR has consistently remained within the normal range, and I generally do not exhibit any symptoms, which has left me without a definitive diagnosis. Recently, I began experiencing episodes of chest discomfort, each lasting approximately five days to a week. The sensation is heavy, and I feel acute pain when I take deep breaths or lie down. Thus far this year, I have encountered about four such episodes. As a result, my doctor referred me to a cardiologist, who is considering pericarditis as a potential diagnosis. I was prescribed colchicine at a dosage of 0.6 mg twice daily for several months, in addition to ibuprofen as required, and advised to refrain from any physical exercise during this period. Consequently, I have halted all strength training and cardiovascular activities and have focused on rest instead. I recently underwent another round of blood tests; however, the results were disappointing as my CRP levels did not show any improvement. I was hopeful for a reduction in CRP and am left questioning whether pericarditis is indeed the correct assessment. **Latest Lab Results (February 2026):** * CRP: **3.9 mg/dL** (normal range: 0–1) - elevated * ESR: **16 mm/hr** (normal range: 0–20) - within normal limits **Previous CRP Levels (mg/dL):** * November 2025: 3.0 (elevated) * June 2025: 3.3 (elevated) * February 2025: 3.0 (elevated) **Previous ESR Levels:** * November 2025: 12 (normal) * June 2025: 22 (slightly elevated) * February 2025: 22 (slightly elevated) * October 2024: 16 (normal) For the past five to six years, my CRP has consistently stayed in this elevated range, with the lowest recorded value being 2 mg/dL. Has anyone else gone through something similar or have insights to offer? Thank you so much!

Thank you for sharing your situation. It sounds like you are going through a complex and concerning health issue with your elevated CRP levels and chest discomfort. Let’s break down some key points and provide you with actionable advice based on your experience and symptoms.
Summary of Main Points:
- You are experiencing recurrent chest discomfort with elevated CRP levels, which may suggest pericarditis.
- Your ESR levels remain normal, and past autoimmune tests have been negative.
- You have been prescribed colchicine and told to avoid physical exercise.
Explanation:
C-reactive protein (CRP) is a marker of inflammation in the body. Elevated levels suggest that there is inflammation present, which can be due to various conditions, including infections or autoimmune diseases. Your normal ESR levels indicate that there may not be a widespread inflammatory process, as ESR can reflect different conditions. The symptoms you're experiencing—heavy chest discomfort and acute pain while breathing or lying down—are concerning and align with pericarditis, an inflammation of the pericardium (the membrane surrounding the heart).
It's important to monitor how your symptoms and lab values change over time, particularly since your CRP levels have not improved despite treatment.
Next Steps (Prioritized):
-
Keep Monitoring Symptoms: Track the frequency and intensity of your chest discomfort episodes, including any changes in pain when lying down or breathing deeply. This information can be valuable for your healthcare provider.
-
Follow Up with Your Cardiologist: Schedule a follow-up appointment to discuss your ongoing symptoms and CRP levels. It may be necessary to re-evaluate your diagnosis or consider other imaging studies, such as an echocardiogram, to assess for pericarditis or any other heart-related concerns.
-
Adhere to Prescribed Treatments: Continue taking colchicine as directed and use ibuprofen to manage discomfort. Ensure you are following guidelines on avoiding physical exercise until you have a clearer understanding of your condition.
-
Lifestyle Adjustments: Focus on rest and manage stress levels as stress can exacerbate inflammatory responses. If applicable, consider gentle breathing exercises to help manage discomfort and improve lung expansion.
-
Explore Dietary and Lifestyle Factors: Discuss with your healthcare provider about any dietary adjustments or other lifestyle factors that may contribute to generalized inflammation. Certain foods, regular hydration, and stress management techniques can help improve your overall health.
-
Consider Further Testing: Inquire if your healthcare provider thinks additional blood tests or imaging may be beneficial to rule out other conditions.
Empathetic Note:
It’s completely understandable to feel frustrated and worried about your health situation, especially with the uncertainty surrounding your symptoms. Remember that you are not alone in this, and seeking further clarification will help provide you with the answers you are looking for. Staying proactive in your health management will be crucial. Please keep your healthcare team informed of any significant changes in your condition. You are taking positive steps by seeking information, and I wish you the best in finding clarity and support.

Managing Hand Burns: Hydrocolloid and Neosporin Recommendations
Three days ago, I accidentally burned my hands while dealing with hot wax at my workplace. Since the incident on Wednesday, I have been treating the burns using cold water, Neosporin, and hydrocolloid bandages, as my initial treatment involved just regular band-aids available at work. I have changed the bandages a few times, carefully washing the area and reapplying Neosporin each time. Given that I can't completely avoid exposing them to moisture at work, I anticipate needing to change the bandages every day. Initially, there was a blister on my thumb that retained fluid, but it burst when I removed the hydrocolloid the following day. I’m wondering if sticking to this treatment plan is advisable. They are painful, but I don’t observe any signs of infection. Also, could anyone provide insights on how long the healing process might take? Thank you for your help!

Struggling with Persistent Illness
Age: 37 Height: 5’2 Weight: 186 Gender: Female Medical Background: Allergic asthma, chronic pain, unilateral vestibular hypo-function, binocular vision dysfunction (all resulting from a motor vehicle accident four years ago), and non-alcoholic fatty liver disease. Greetings, Medical Professionals! My family of four and I have been experiencing intermittent illness since New Year's Eve. We’ve tested positive for Influenza A, and that's the only diagnosis we currently have, here in Southern California. Given my medical history, I tend to feel the effects the hardest, while my children, who also suffer from asthma and allergies, are similarly affected. My husband is generally healthy and appears to be in better shape, but he does manage Type 2 Diabetes. My children and I have been really unwell; we've dealt with high fevers, persistent coughs, severe colds, and sinus infections (we usually end up on antibiotics after a week of no improvement). I’ve had chest X-rays done, and thankfully, the results came back clear. We have consistently tested negative for both COVID-19 and strep throat. What are we missing? Why do we keep facing these health challenges? I trust my healthcare provider completely, yet my mother has started to influence my feelings, suggesting that the doctors aren’t thoroughly investigating our symptoms. While it’s true that my kids and I have been ill frequently, I assumed it was due to our existing conditions of asthma and allergies. My mom mentioned knowing someone who experienced frequent sickness and later was diagnosed with stage 4 breast cancer. I stay on top of my mammograms, gynecological check-ups, and my lab results are largely normal, aside from the fatty liver issue, which I am actively addressing. We’re not engaging in risky behaviors, so why are we being hit so hard? At what point should we be really worried about our health situation?
Persistent Rapid Heartbeat and Anxiety
I’m a 28-year-old female, weighing 110 pounds and standing at 5 feet 1 inch, and I follow a vegetarian diet. Recently, I have been grappling with severe panic attacks right after I wake up. These episodes have caused excessive sweating and nausea, often leading me to vomit, and then I typically drift back to sleep. When I eventually wake up again, even if it's only after a short nap of about 20 minutes, I generally feel significantly improved. Initially, I suspected that my frequent use of marijuana was the underlying cause of these disturbances. As a result, I ceased all marijuana usage a few weeks ago, only indulging in an edible during the Super Bowl. Since I stopped using it, the panic attacks have subsided. Though I still experience acute anxiety attacks, they do not include a rapid heartbeat; rather, the symptoms are characterized by overwhelming anxiety, nausea, profuse sweating, and episodes of shivering. Last Thursday night around 10 PM, I began to feel anxious, and by midnight, as I was preparing for bed, my heart began racing uncontrollably. It took nearly two hours for my heart to stop pounding so forcefully that it felt as though it might leap from my chest, allowing me to finally get some sleep. This morning, I awoke around 8 AM with a surge of anxiety and a racing heart. Although the anxiety subsided within two hours, my heart rate showed no signs of returning to normal. Typically, my resting rate is around 65 beats per minute, but today it has fluctuated between 80 and 105 beats per minute. It is now approaching 3 PM, and despite continuing with my daily activities, I am increasingly anxious about my heart rate's inability to stabilize. Is there anything I can do to help regulate it? At what point should I seek medical advice?
Concerns After a Childhood Head Injury
I am a 25-year-old female, standing at 5 feet 6 inches and weighing 140 pounds. At the age of 10, I suffered a head injury due to a car accident, which led to noticeable changes in my behavior. Among these changes, I struggled with self-harming tendencies. There were instances where I would strike my head forcefully against hard surfaces, resulting in nosebleeds. This behavior happened on two occasions. Given these past incidents, I would like to understand how concerned I should be about my current health as a result of these experiences.
