Experiencing Heart Pounding After Stopping Sudafed: Is It Cause for Concern?
At 24 years old, I've been experiencing a sensation that my heart is racing as if it's about to burst. This all started after I was dealing with a severe sinus infection and decided to take Sudafed extended-release tablets for six consecutive days. Ever since I discontinued the medication, my heart feels as though it's beating excessively hard, reminiscent of a fight-or-flight response. Should I be alarmed by this change, or could it possibly be a side effect from the Sudafed I had been using?

Heart palpitations after stopping Sudafed can occur and may be linked to several factors, including withdrawal effects, lingering effects from the medication, or other underlying issues. Here’s a structured response to address your concerns.
Main Points:
- Heart pounding can result from stopping Sudafed, which may include withdrawal symptoms or heightened sensitivity to your body's normal rhythms.
- It’s crucial to monitor your symptoms and consider other potential causes.
Explanation:
Sudafed (pseudoephedrine) is a decongestant that can raise your heart rate and blood pressure during use. After stopping the medication, your body may take some time to readjust, which can lead to sensations like your heart racing or pounding. Additionally, anxiety or stress associated with illness can heighten awareness of your heart rate. Although this isn’t uncommon, it’s important to rule out other potential issues, especially since you are experiencing this sensation after prolonged use.
Next Steps:
-
Monitor Symptoms: Keep track of when these racing heart sensations occur. Note any other symptoms like shortness of breath, chest pain, or swelling in your legs, as these may indicate a more serious issue.
-
Stay Calm and Hydrated: Ensure you’re staying well-hydrated and practice calming techniques such as deep breathing or relaxation exercises, which can help manage sensations of panic or anxiety.
-
Limit Stimulants: Reduce or eliminate caffeine and other stimulants from your diet, as they may exacerbate racing heart sensations.
-
Consult Your Healthcare Provider if Necessary: If your symptoms continue, worsen, or if you develop additional concerning symptoms (such as significant shortness of breath, chest pain, or any swelling), consider reaching out for professional advice. It's always better to be cautious when it comes to heart-related symptoms.
Feel assured that many people experience similar sensations after discontinuing medications like Sudafed. Keeping an eye on your symptoms and taking the steps mentioned can help you manage your comfort and well-being.

Concerns About Ear Irrigation at the Pediatrician's Office for My Son
Summary: Can using a spray-type irrigation for ear wax removal harm a five-year-old? My child had a extreme reaction and experienced significant pain during and shortly after the procedure. I have a five-year-old son who suffers from severe allergies to both foods and environmental factors, alongside eczema which is mostly controlled. He takes Famotidine to manage reflux and a daily children's multivitamin, but does not regularly take any other medications. He has no history of surgeries. Although he has consulted with an ENT in the past, I don’t believe this is particularly relevant to the current situation, yet I will provide details later. During a recent well-visit at the pediatrician's office for five-year-olds, my son struggled with the hearing test, which marked the first time he did not perform well. In this examination, he wore headphones that emitted various beeps and was supposed to indicate which ear he heard the sounds from. The staff expressed concerns regarding his performance on the left side. As our assigned provider, the Physician's Assistant (PA) examined his ear and noted the presence of wax, suspecting it might be impeding his hearing. When she attempted to use a plastic curette, my son resisted and stated that it hurt. The PA remarked that the wax was harder than she anticipated, leading her to opt for an irrigation method to remove it. The nurses proceeded to administer some red-tinted drops, which he tolerated other than their cold temperature. A few minutes later, he laid down, and they used a spray bottle to irrigate his ear. At this point, he screamed as though we had never experienced before—he fought against the staff and cried intensely, even holding his breath to the extent that they needed to remind him to breathe. His reaction was reminiscent of when he has sustained a severe injury, such as from a significant fall. His cries of pain made it clear that he was genuinely suffering. After only a few moments, they decided to halt the procedure, presumably realizing that his discomfort was not an act of dramatization, and I was on the verge of stopping them myself due to my rising concern. When he eventually settled down, I inquired about the nature of his pain: whether it was a hot or burning sensation, a sting from the cold water, or a feeling of pressure in his ear. He communicated that it felt like it was going to burst inside, which suggests pressure-related pain. The irrigation attempt did not fully clear the wax they noticed. Now they are recommending that we use Debrox drops daily combined with a warm washcloth pressed against his ear after a steamy bath each night. We are to return in two weeks to check if the wax has been successfully removed and to retest his hearing. Though he appears to be okay now, he is visibly upset due to the discomfort from the procedure, especially since he had begged them to stop. He has also mentioned a sensation of water still being trapped in his ear and has been tilting his head intermittently as if it bothers him. This all transpired today right after the irrigation session. Could the forceful spraying of water have caused any damage to his eardrum, especially considering the intensity of his screams? I have previously experienced a perforated eardrum and am anxious about the potential harm this procedure may have inflicted on him. We avoid using Q-tips and inserting anything into his ears. What preventive measures should we adopt routinely to avoid wax buildup? This marks the second instance of noticeable wax at his pediatric visits, despite him bathing daily. I am puzzled as to why only one side is accumulating wax. Last year, the first attempt at wax removal was successful using a curette. ENT Background: At age three, my son was having trouble sleeping. An ENT suggested a tonsillectomy and adenoidectomy, although there were no other alarming symptoms to justify the surgery besides his restlessness at night. We sought a second opinion, where the new ENT indicated that while his tonsils appeared fine, his adenoids were mildly enlarged and might be beneficial to remove. However, due to COVID-19 and RSV, the surgery was postponed twice, leading us to reconsider the necessity of the operation. Given that he is now sleeping better, we have yet to pursue surgery thus far. I appreciate you taking the time to read through this lengthy account!
Experiencing Heart Palpitations When Turning Eyes to the Side?
As a 19-year-old male dealing with gastroesophageal reflux disease (GERD) and strabismus, I have recently noticed that I experience heart palpitations when I look sharply to either side. I’m uncertain if there’s a connection between these two issues, but that’s the only link I can draw. Generally, my health is good, although I was born prematurely. The palpitations feel like a combination of fluttering and pounding, and they occur specifically when I shift my gaze dramatically. I discovered this phenomenon somewhat accidentally during my annual eye appointment. Should I be concerned about this, or is it something that can be overlooked?
Deciphering My Laboratory Findings
Although I won’t have a consultation with my doctor for another month, I received most of my lab findings today and am eager to comprehend their implications and trends. I am 24 years old, weigh 115 pounds, and my height is 4 feet 11 inches. I do not smoke and consume alcohol infrequently, approximately two drinks monthly. My blood pressure and glucose levels are within normal ranges, and my heart rate is also typical. Additionally, there is a familial history of diabetes and kidney and liver disorders, alongside irritable bowel syndrome (IBS). I have been experiencing chronic diarrhea for over six months, characterized by a yellowish hue. During my recent examination, my doctor pressed on my abdomen and found no abnormalities or pain. **Celiac Disease Screening:** There are no indicators of celiac disease based on the serological tests. **C-Reactive Protein Test:** My result was 3.8, which is elevated. **Comprehensive Metabolic Panel:** All results fell within normal limits, except for an ALT (SGPT) level of 9, which is considered low. **Thyroid Stimulating Hormone with Free T4 Reflex:** This test is in the acceptable range, with a result of 1.42. **Lipid Profile:** - Cholesterol: 249 (elevated) - Triglycerides: 189 (elevated) - HDL (High-Density Lipoprotein): 45 (low) - Cholesterol/HDL Ratio: 5.5 (elevated) - LDL (Low-Density Lipoprotein) Calculated: 166.2 (elevated) **Hemoglobin A1C:** - Hemoglobin A1C: 4.8 - Estimated Average Glucose (eAG): 91 From what I have gathered, my cholesterol levels are quite concerning (I recognize that managing them is crucial), and it appears that I may be consuming a diet high in fats that my body is struggling to process effectively. However, I remain uncertain about whether this issue extends to my organs.

Unexpected Heart Murmur at 24: Concerns About HOCM
At the age of 24, standing at 4'11" and weighing 98 lbs, I've recently been notified by my doctor that I have a slight heart murmur. This diagnosis is noteworthy due to my family history; both my father and grandmother suffered from Hypertrophic Obstructive Cardiomyopathy (HOCM). I typically have check-ups with my cardiologist every couple of years, though it’s been two years since my last appointment. During that visit, an echocardiogram was performed, which yielded normal results, and there were no murmurs detected—my cardiologist was quite thorough in his examination. Given that my grandmother had a serious surgical procedure and faced significant health challenges, I'm understandably anxious about this new finding. My general practitioner was somewhat vague regarding the specifics of the murmur's location but did mention it during my visit today. Fortunately, I've secured an appointment with my cardiologist next week to explore this matter further and ease my worries.
