Concerns Regarding Erythromycin and Long QT Syndrome
Hello everyone. I am a 38-year-old woman currently prescribed Erythromycin for a duration of 28 days to address my digestive motility challenges. Throughout this treatment period, I have been extremely anxious about the potential risk of developing long QT syndrome. There's a possibility that I might need to continue this medication for another month, as it’s the only option that enables me to consume solid foods right now. What is the likelihood that I could experience long QT syndrome as a side effect of this drug? I have an appointment with my doctor today, during which I plan to request an EKG, but I would appreciate some guidance beforehand. This issue is quite serious to me, so I kindly ask for informed responses only. Thank you for your understanding! Currently, I am taking the following medications: - Lamictal 50 mg - Propranolol 20 mg - Klonopin 0.25 mg as needed - Remeron 15 mg - Erythromycin 250 mg, three times daily before meals

It's understandable to be anxious about the potential side effects of medications, especially when it involves something as serious as long QT syndrome. Erythromycin can be associated with this condition, but the likelihood of developing it varies based on individual risk factors and other medications you are taking.
Main Points:
- Erythromycin and Long QT Syndrom: Erythromycin can prolong the QT interval in some individuals, which is a measurement of heart rhythm on an EKG. However, not everyone who takes this medication will experience this side effect.
- Risk Factors: Your risk may be influenced by the medications you are currently taking and any underlying heart conditions. Propranolol, for instance, is often used to manage certain heart conditions and anxiety.
Explanation:
Long QT syndrome can indeed be a concern when taking certain medications, including Erythromycin. Factors that can increase your risk include existing heart issues, electrolyte imbalances (like low potassium or magnesium), or interactions with other medications. Since you are on several medications, it's wise to monitor for symptoms that could indicate a heart rhythm issue, such as palpitations, dizziness, or fainting.
Next Steps:
- Discuss Concerns with Your Doctor: During your appointment, share your anxiety regarding long QT syndrome and request an EKG. This test can help you and your doctor understand your current heart rhythm.
- Monitor Symptoms: Keep track of any unusual symptoms you experience, such as lightheadedness or rapid heartbeat, especially when changing positions or after taking medications.
- Evaluate Medication Interactions: Ask your doctor about the combination of your current medications and their possible interactions with Erythromycin, particularly the implications for heart rhythm.
- Hydration and Diet: Maintain good hydration and a balanced diet rich in potassium (like bananas and avocados), as this can support overall heart health.
It's great that you are being proactive about your health, and your concerns are valid. You're taking the right steps by planning to discuss this with your doctor. Feel free to reach out if you have further questions or need more support.

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.
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!
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.
Concerns About My Toes
Age: 30, Female Currently, I am on the lookout for a reputable podiatrist in my vicinity. However, I've encountered a perplexing issue with my foot. Just last night, I noticed a growth on the side of my toe, something entirely new to me. I maintain a nutritious diet and have a demanding job that requires me to be on my feet quite often. My footwear includes brands such as Brooks Ghost Runners, Hoka Bondi 9’s, and Nike Motiva’s, and I don’t opt for restrictive socks. I also apply Vick’s Vaporub to my feet, a practice handed down from my family, and stick with simple, non-fragrant lotions like Vanicream and CeraVe SA Cream for my skin. In addition, I am curious about the my big toenail's change in color. What might be the underlying reasons for this? Also, I have these persistent dark spots on my toes that I've struggled with since my days on the runway. Despite my efforts, nothing has succeeded in lightening or diminishing their appearance. I'm just looking to determine if there might have been a factor from the past that could have contributed to these issues. I’m not sure what else to include, but I’m open to answering any questions you might have. Thank you for your attention! Best wishes from a worried soul!
