Can High Sodium and Low Potassium/Magnesium Diets Lead to Pitting Edema?
Hello! I'm contemplating whether a visit to a cardiologist is necessary. The question posed in the title is what I’m curious about, but I’d like to share additional information that might be important for understanding my situation: - I've recently put on some weight due to a happy relationship, which has involved an increased intake of processed foods. - I also consumed alcohol quite frequently over the summer, but I have completely cut it out after recognizing it was becoming problematic. - The pitting edema I've experienced is localized to just above my shins. After a long day, I frequently notice prominent sock markings, which seem worse than before. - The last time I was at my current weight, I also dealt with pitting edema. I’m uncertain if it disappeared when I lost weight in between, but I certainly felt better overall during that phase. Other symptoms I've been experiencing include: - A combination of headaches and chest discomfort that arises with adrenaline rushes linked to anxiety, which is difficult to articulate. - Occasional aches in my left arm and shoulder, not directly associated with the headaches or chest pain. This might be anxiety-related? - I do not experience breathing difficulties when lying down, and I can usually fall asleep without issues. - Shortness of breath only surfaces during exertion. There's no accompanying lightheadedness or dizziness. - My resting heart rate is around 100 beats per minute, which has noticeably increased with my weight change. Regarding my medical history: - In 2022, I visited the ER due to chest pain and vomiting. An EKG revealed right axis deviation and right atrial hypertrophy. A subsequent discussion brought up the possibility that low potassium levels in my blood might have contributed to those findings. - In 2021, a cardiologist recommended a Holter monitor to investigate potential arrhythmias, which returned normal results. - In 2018, an EKG indicated arrhythmia, though I cannot recall the specifics. Given this background, I’m eager to hear your thoughts on my dietary concerns and symptoms, and whether they warrant a cardiology consultation.

The relationship between diet, specifically high sodium and low potassium/magnesium intake, and conditions like pitting edema is an important concern. Your symptoms, particularly the localized swelling, could indeed be influenced by dietary factors, but other health considerations also need to be factored in.
Explanation:
-
High Sodium and Low Potassium/Magnesium: Diets high in sodium can cause the body to retain more water, leading to edema (swelling). Potassium helps counteract sodium’s effects, supporting fluid balance. Low magnesium levels can also contribute to blood pressure issues and may affect heart health.
-
Weight Gain and Edema: Increased weight, especially from processed foods high in sodium, can exacerbate fluid retention. Changes in diet and lifestyle, including alcohol consumption, may have contributed to your symptoms.
-
Other Symptoms: Your resting heart rate of 100 beats per minute, along with the anxiety-related symptoms, may indicate increased stress on your body. While some symptoms may relate to anxiety, it’s essential to distinguish these from potential cardiac issues, especially given your past medical history.
Next Steps:
-
Dietary Adjustments:
- Reduce Sodium: Start by cutting back on processed foods and high-sodium items. Aim to limit your sodium intake to less than 2,300 mg per day (lower for certain health conditions).
- Increase Potassium and Magnesium: Incorporate foods rich in potassium (like bananas, spinach, and avocados) and magnesium (such as nuts, seeds, and leafy greens) into your diet.
-
Symptom Monitoring:
- Keep a journal to track your symptoms, including the timing and triggers for your headaches, chest discomfort, and edema. Note how changes in diet may impact these issues.
-
Hydration: Ensure you're drinking enough water. Proper hydration can help balance sodium levels and may reduce edema.
-
Physical Activity: Gradually incorporate regular physical activity into your routine if you haven't already. Walking or light exercise can help improve circulation and decrease swelling.
-
Consider Professional Guidance: Given your past cardiac concerns and current symptoms, it would be wise to consult a cardiologist, especially if your symptoms worsen, if the edema persists despite dietary adjustments, or if you experience new symptoms like increased shortness of breath or severe chest pain.
Taking these actions could provide you relief and clarify if your symptoms are primarily related to dietary choices or need further medical evaluation. Don’t hesitate to reach out for professional help to address your concerns effectively.

Experiencing Uncertainty: Possible Ischemic Attack?
Greetings, everyone, including healthcare professionals. For the past year, I've been managing high blood pressure, and I'm currently prescribed a regimen that includes Amlodipine at 10 mg and Bisoprolol at 5 mg. At 44 years old, I’m a woman who is classified as overweight and also deals with hypothyroidism, low ferritin levels, liver issues, and slightly elevated cholesterol levels. Typically, my medications maintain my blood pressure within a range of 110/70 to 140/80. However, two days ago, I experienced a stressful episode, causing my systolic pressure to spike to 155/95. Upon standing, I sensed weakness in my left arm, which felt as if it were slightly twisting. A wave of panic hit me, and I feared I might be incapacitated or having a stroke. Despite my anxiety, I was still able to grasp a glass and tightly close my fist. Briefly, my right arm felt a mild sensation that lasted only a second. This peculiar feeling persisted for roughly a minute. I then consumed some mint tincture mixed with alcohol and engaged in deep breathing exercises, which remarkably alleviated my symptoms and brought my blood pressure back to a stable level. I contacted my physician, who inquired about my symptoms and their duration. Aside from the discomfort in my arm, I wasn't experiencing any additional issues. A second doctor relieved me of any immediate concerns regarding the necessity for an MRI, and since I underwent one a month prior that showed no abnormalities in my cranial blood vessels, I felt some reassurance. Now, back home and with lingering fears of having experienced an ischemic attack, I wonder if an ultrasound of the neck arteries is warranted. Do my symptoms indicate a potential attack? What steps should I take next? Has anyone faced a similar situation? Thank you all for your insights.
Seeking Guidance on Ice Treatment Post-Surgery
I’m a 34-year-old male, weighing 158 pounds and standing 5 feet 6 inches tall. I lead a non-smoking lifestyle, consume three alcoholic drinks weekly, and do not have any known allergies. I'm currently recovering from right hand and wrist surgery, which took place five weeks ago. I need some advice regarding the use of ice for my treatment, as my wrist remains quite swollen. While I understand the advantages of icing, I find the experience quite intolerable. I attempt to immerse my hand and wrist in ice water completely, but the pain is so intense that I can barely last more than 15 seconds. Is this a challenge of mental resilience where I need to push through the discomfort for the sake of a proper 10-minute soak? In the past, I worked with racehorses, and we would apply ice to their legs for 30-minute sessions, significantly accelerating their recovery. I recognize the effectiveness of this method, yet the pain from the cold is unbearable. Should I endure this discomfort for longer periods?
Rash on My Arm: Should I Be Concerned?
Hi there! I’m a 65-year-old female, and for the past four days, I’ve been dealing with a strange rash on my arm. Unfortunately, I can’t visit a healthcare professional until Monday, so I’m hoping to get some clarity in the meantime. I’ll share some images. If they don’t upload here, I’ll post them in the comments instead. The first image, taken last night, is a bit out of focus, but this morning, the rash has appeared even redder. Although it doesn’t itch now, I did experience some itching during the initial two days. As for my health history, I generally don’t have major health concerns apart from elevated cholesterol levels and a recent A1C reading of 5.9, but I do not have diabetes. I keep fairly active for my age group. During the first couple of days, there was some pus, and I managed to clean it with an alcohol wipe, which helped remove it. Could this be related to a spider bite? I noticed some small spiders (specifically daddy long legs) in my bedroom, especially near the balcony door, and I eliminated a few of them today, so that could be a possibility. Should I be wary of any serious complications from this rash? Any advice would be immensely appreciated! My ER co-payment is quite steep, and there’s no urgent care facility nearby. My only option is to request an appointment with my primary care physician next week, but I’m uncertain if it’s something that warrants immediate attention.
Navigating Recurrent Prostate Cancer: A Patient's Journey
As a 60-year-old man living in New York, I faced a challenging battle with prostate cancer approximately 4.5 years ago. My initial biopsy results indicated a Gleason score of 6. However, in September 2025, my PSA levels alarmingly soared to 27.7. To investigate the possibility of an infection, my doctor prescribed a month-long course of antibiotics. Afterward, my PSA levels showed a slight reduction, dropping to 25.5. Following another biopsy procedure, the Gleason score unexpectedly escalated to 10. This prompted serious discussions with my healthcare provider. He explained that, given the radiation treatment I had previously undergone, the surgical removal of my prostate would be quite complex, with very few surgeons willing to perform such a procedure. Consequently, I sought a second opinion from a specialist in urological cancer. The specialist echoed similar concerns, indicating that the potential complications could severely affect the urethra and rectal lining. Instead of surgery, he proposed cryoablation as a viable alternative. Simultaneously, I commenced treatment with testosterone hormone blockers. To say that this experience has been frustrating is an understatement. Most importantly, I also struggle with urination issues that complicate my daily life. I am reaching out for any insights or advice that might assist me in navigating this difficult situation.
Experiencing Widespread Muscle Weakness
I’m a 36-year-old male and have recently been facing a troubling situation where the muscles throughout my body seem to be losing function—including my eyelids. The trouble began in May 2021 when I lifted a heavy garbage can with my right arm in a shrugging action. Following that, I felt a combination of pain and weakness concentrated in my right shoulder blade, as well as my shoulder and collarbone. Soon after, I noticed my shoulder began to pop and click. Afterward, I consulted with an orthopedic specialist who conducted x-rays on both of my shoulders. He informed me that everything appeared normal and dismissed the popping sounds as inconsequential. I also mentioned experiencing neck pain, but he indicated that addressing neck issues wasn’t his area of expertise. He diagnosed me with bilateral shoulder and neck discomfort and recommended physical therapy. The day after my appointment, I attempted to adjust my position in my desk chair by leaning on the left armrest, putting my forearm under the weight of my body. Suddenly, my shoulder jolted, and I felt a sharp weakness in my arm, accompanied by popping and clicking noises, similar to what happened with my right arm. I reached out to the orthopedic office to inform them about this incident, but the physician assistant who responded said the doctor would not see me again simply due to how I was sitting, and suggested I attend physical therapy first. She mentioned that if I continued to experience weakness, a neurologist might be necessary. Feeling concerned, I returned to my primary care physician for a follow-up appointment and recounted my experience. He didn’t appear worried, and my blood tests returned normal results. During the summer of 2021, I began physical therapy where the therapist diagnosed me with strains in my trapezius and rhomboid muscles. The subsequent therapy sessions consisted of painful exercises and stretches, yet I observed little to no improvement in terms of strength or stability. Activities like using the arm bike and weight machine were excruciating, and I frequently inquired whether my symptoms could be attributed to a tear or nerve damage, but the therapist insisted that was not the case and dismissed my concerns. After my tenth session, I decided it was best not to return. In April 2022, I visited a neurologist. I struggled to lift myself onto the examination table and needed assistance from a step stool. He didn't suspect any neurological issues when I asked him about an EMG or other assessments, he declined to proceed with those tests. Disheartened by these experiences, I chose not to pursue further medical consultations. Fast forward to April 9, 2025, I misstepped while descending some stairs, causing my right heel to catch, and I landed hard with my toes pointed. I had no visible signs of injury such as swelling or bruising, but soon after, I began to experience persistent pain and weakness, especially in my toes and the arch of my foot. By April 13, I instinctively elevated the toes on my left foot, and to my dismay, the same pain and weakness emerged, again without any visible signs like bruising. Since then, both feet have lacked strength, and my big toes feel unusually floppy. In July 2025, I had a troubling experience after having my hair washed at a salon. I held my neck in an awkward position for the duration, which resulted in a burning sensation. Regrettably, I didn’t express my discomfort, fearing a scene. Following this, I noticed significant weakness in the muscles at the front of my neck, under my chin, which gave the appearance of a receding chin. Additionally, my facial muscles, particularly in my cheeks, felt weak and could easily be pressed in with minimal resistance. In January 2026, I bought a new game controller for my laptop, having not played video games for a long time. Initially, it was manageable, but soon after, my hands and forearms began to feel uncomfortable and painful. This discomfort escalated significantly to where I had to discontinue use completely; my hands felt drained of energy and experienced achiness, tingling, and numbness. Then, on February 3, 2026, while seated and using my laptop, I noticed a peculiar sensation when moving my eyes. My eyelid muscles felt weak, and one of my eyelids began twitching. I found it increasingly difficult to open my eyes as widely as I used to. I plan to see a primary care physician once more, but I’m uncertain how to communicate all of this effectively to receive proper care. My circumstances have reached a point where my parents must assist me with everyday tasks, including driving, opening doors, and even lifting light objects. My ability to raise my arms above my head has become severely limited as well.
