Could My Heart Be Struggling with the Medications Delivered via My Central Line?
Greetings, I'm a 23-year-old female weighing 105 pounds, grappling with chronic illnesses, particularly severe gastroparesis (I've been unable to eat for four years) and dysautonomia affecting both my parasympathetic and sympathetic nervous systems, characterized by appropriate sinus tachycardia ranging between 110-120 beats per minute since birth, without any history of premature birth or additional health complications. Additionally, I experience low blood pressure, fluctuating between 100/66 and 90/50, and I'm currently undergoing assessment for hypermobile Ehlers-Danlos syndrome. My medical regimen includes 24-hour total parenteral nutrition (TPN) that I've been on for four years, consisting of 1750mL of SMOF lipids delivered at a rate of 79.4mL/hr, along with IV medications such as Protonix (administered as an IV push), famotidine (mixed with the TPN), Phenergan (delivered through a diluted drip of 6.25mg/0.5mL in 50mL saline), a 5mL heparin flush for the lumens, and IV acetaminophen upon necessity (1000mg in 100mL, infused at a rate of 400mL/hr). Four years ago, a 12 French dual lumen silicone Hickman catheter was placed, tunneled in my right chest and entering the right internal jugular vein, to address my failure to thrive. Through the white lumen, I consistently infuse TPN, while the red lumen is used for medication administration and laboratory draws. Historically, flushing the line has been trouble-free; I never experienced discomfort or chest pain associated with this process. However, about a month ago, I started encountering severe chest pain whenever I flushed either lumen, prompting me to proceed cautiously with the flushes. The sensation felt akin to having a heavy weight pressing down in the middle of my chest, and it lingered even into the next day. Concerned about my symptoms, I visited the emergency room, where an IR contrast study revealed a minor extravasation in the catheter’s subcutaneous tunnel. Subsequently, the catheter was replaced on February 18th, matching the original model, and post-placement chest X-rays confirmed its proper positioning. Monthly lab checks have consistently returned normal results, and I have not experienced any infections related to the line. Despite the catheter being replaced, I continue to suffer from chest pain during the flushing process. The actual infusions remain painless, leaving me puzzled over the cause of this issue. A cardiologist assessed my situation and indicated that these flushes would not affect my heart. I have undergone three electrocardiograms, all indicating normal results, alongside an echocardiogram that also came back clear. For four years, I had no issues with flushing my line, so I can't help but wonder if I'm neglecting another underlying factor contributing to my current discomfort.

It sounds like you're experiencing significant discomfort related to your central line flushes, which can be concerning given your medical history. The chest pain you're feeling during flushing, especially after previously having no issues, warrants attention, and it's understandable that you're looking for clarity on this.
Main Points:
- Chest pain during flushing can have various causes, including issues related to your central line placement, the specific IV fluids or medications used, or even your body's response due to existing chronic conditions.
- Even with normal cardiac assessments, the discomfort suggests a need for more investigation into your central line or the flushing technique.
Explanation:
Your chronic conditions, like gastroparesis and dysautonomia, can complicate your body's responses to medical interventions. The recent replacement of your catheter and the persistent chest pain during flushes could indicate:
- Mechanical issues with the catheter: Even with current normal positioning, some minor internal issues can lead to discomfort.
- Back-pressure created during flushing: This could be more pronounced if your vascular resistance is affected by your autonomic dysfunction.
- Chemical irritation or reaction: Some medications or solutions, when flushed, can irritate the vessel or surrounding tissues, especially if there's a minor injury or compression.
Next Steps:
-
Assess the Flushing Technique: Ensure that flushing is done slowly and steadily. Consider discussing with your healthcare provider to evaluate your technique and if modifications are needed.
-
Documentation of Symptoms: Keep a detailed diary of when the chest pain occurs, its intensity, and any other symptoms present. This can provide critical information for your healthcare team.
-
Revisit Specialties: Given that your cardiologist has ruled out straightforward cardiac causes, consider discussing your symptoms with:
- A vascular specialist to evaluate the blood flow and function of the catheter.
- A gastroenterologist, as your gastroparesis and autonomic issues might contribute to vascular responses.
-
Monitor Changes: If you notice any changes in your symptoms, such as new types of pain, increase in intensity, or additional symptoms like shortness of breath, seek immediate medical advice.
-
Maintain a Dialogue with Your Healthcare Team: Continue to express your concerns, even if assessments yield normal results. Sometimes, persistent issues require persistent discussions to uncover underlying causes.
It's important to stay proactive about your symptoms and continue seeking clarity on this matter. Your comfort and well-being are crucial, and addressing these concerns with your medical team can help you find a path forward.

Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
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.
