Concerns Over Unusual Health Reactions During Walks [31M]
Greetings, I am a 31-year-old man currently engaged in a goal of achieving 10,000 steps each day to assist with weight loss. However, over the past three weeks, I've begun to face some troubling health symptoms. I've increasingly noticed that I feel excessively warm even when the temperature is only around 21 degrees Celsius, accompanied by irregular heartbeats and excessive sweating. During my walks, there are moments where I experience a strange mental fog, which leaves me feeling somewhat disoriented and lightheaded, as if I might faint. Additionally, my calves have been aching significantly during these walks. This situation is concerning because just four weeks ago, I experienced none of these symptoms, even during hotter weather conditions. Now, my body seems unable to tolerate temperatures above 22 degrees Celsius. While I do have some occurrences of these symptoms while at rest, the vast majority happen during physical activity. It's important to note that I’m not engaging in running; it’s merely a leisurely walk. I'm quite anxious about what might be happening to me.

It’s good to hear you are proactively engaging in physical activity, but I understand your concern regarding the new symptoms you’re experiencing during your walks. Let’s break down the main points and prioritize what you can do to address these issues.
Main Points:
- Increased warmth and sweating: This could be related to how your body is regulating temperature during exercise.
- Irregular heartbeats and lightheadedness: These could indicate an adjustment period or an underlying issue that requires attention.
- Calf pain: This could result from overuse or muscle strain from increased activity.
Explanation:
Feeling hot, experiencing irregular heartbeats, and having a mental fog during physical activity can occur for various reasons. Factors can include dehydration, improper warm-up, anxiety, or even underlying cardiovascular issues that have become more pronounced with increased activity. Calf pain can be attributed to muscle fatigue, strain, or even issues with circulation. It’s important to consider your overall health, hydration status, and the intensity of your walks.
Next Steps:
-
Hydrate: Ensure you are drinking enough water before, during, and after your walks. Dehydration can lead to overheating and increased heart rates.
-
Monitor Intensity: Consider reducing the duration or pace of your walks to see if that alleviates symptoms. Gradually increase your activity level instead of pushing for 10,000 steps immediately.
-
Warm-Up and Cool Down: Incorporate proper warm-up and cool-down stretches to prepare your muscles and help with circulation.
-
Rest and Recovery: Listen to your body. If symptoms persist, take breaks between walks and reassess your activity levels.
-
Symptom Diary: Start keeping track of when these symptoms occur, their intensity, and any other factors (like food intake or rest) that might correlate.
-
Consult a Health Professional: If symptoms continue or worsen, especially the irregular heartbeats and lightheadedness, seeking evaluation from a healthcare provider is important to rule out any underlying conditions such as cardiovascular issues or other health concerns.
Focusing on hydration and pacing yourself is important, but don’t hesitate to seek professional help if you feel uncomfortable or if symptoms don’t improve. You’re taking a positive step for your health, and it’s crucial to do it safely.

Should I Be Anxious About This?
Hello everyone. I'm a 21-year-old female, weighing 150 pounds and standing 5 feet 7 inches tall—thought that might be relevant. A few weeks back, I was ill, which was quite unpleasant. However, there's one lingering issue that's worrying me: I’ve developed a sudden and excessive runny nose since getting better. It’s not the usual mucus; it’s a clear fluid, and it comes on so abruptly that sometimes I have to catch it in my hand because I can't reach for a tissue quickly enough. There was a discussion I came across previously about someone experiencing cerebrospinal fluid leaking from their nose, and it really sent me into a panic. At one point during my illness, I blew my nose too forcefully, felt a pop, and since then, my ears have felt a bit off. I didn’t think much of it at the time. Is there cause for concern here, or am I just overthinking this? This issue has arisen at least twice daily, especially when I lean down or lift something that involves effort.
Understanding Microscopic Hematuria and Uric Acid Crystals
Since 2017, I've been dealing with the presence of trace blood and uric acid crystals in my urine. During a particularly uncomfortable episode characterized by flank pain, I consulted multiple physicians who conducted extensive testing. Ultimately, their advice was straightforward: increase my fluid intake and reduce my consumption of meat. I adhered to these recommendations diligently. Fortunately, I have not experienced flank pain since then. However, during a recent urine analysis, my doctor expressed concern regarding the presence of blood and uric acid crystals in my sample. Notably, my red blood cell count was measured at **64 per high power field (HPF)**, which seems extraordinarily elevated. Yet, as this condition falls under the category of microscopic hematuria, I'm curious about the level of concern I should have regarding this finding. Additionally, how significant should the presence of these crystals be for me? I am a 32-year-old male, not currently taking any medications, aside from vitamin D supplements, and I do not use drugs, tobacco, or alcohol. Thank you for your insights!
Understanding My Father’s Illness: A Quest for Answers
Greetings, I am reaching out in hopes of gaining clarity regarding my father’s medical situation, which has been difficult for me to process. In 2021, my father, aged 61, succumbed to health issues that began with a continuous high fever. He spent several weeks in the hospital without a definitive diagnosis before experiencing liver failure. Eventually, he was moved to a tertiary care facility, where he was first diagnosed with secondary hemophagocytic lymphohistiocytosis (HLH). Just days later, doctors found that he had a high-grade diffuse large B-cell lymphoma (DLBCL) that had spread to both his bone marrow and liver. Despite receiving treatments including steroids, etoposide, chemotherapy, dialysis, and being placed on a ventilator, he passed away a few weeks later from multi-organ failure and sepsis. Tragically, he endured a hypoxic brain injury prior to his death, and I was present at the moment his heart stopped. Unfortunately, he was no longer conscious, and I couldn't have a proper farewell. A few weeks prior to his hospitalization, I noticed he had become increasingly irritable and struggled to comprehend humor. This was out of character for him, and soon after, he exhibited signs of depression, voicing fears about no longer being needed by his family. Around the same time, he developed a severe rash covering his body, which caused burning and itching but miraculously resolved overnight after about two days. I am trying to find answers to several questions: 1. How uncommon is the occurrence of DLBCL alongside secondary HLH, particularly with liver involvement? 2. What causes HLH to progress so rapidly in this context, making it often fatal despite treatment efforts? 3. What physiological changes occur in the body during HLH that lead to such severe multi-organ failure? 4. Were the neuropsychiatric changes and skin rash possible early indicators of HLH or lymphoma? 5. Would recognizing the lymphoma earlier, instead of initially diagnosing HLH, have changed his prognosis, or was this outcome unavoidable due to the disease's aggressiveness? 6. Has anyone in this community encountered similar cases, and what were the outcomes? 7. As his child, should I have concerns regarding any genetic risks for HLH, lymphoma for myself or my sibling, or is the secondary HLH typically non-hereditary? Additionally, is there an elevated risk for developing DLBCL or other forms of lymphoma? I'm not looking for personal medical advice, but I would be grateful for any medical insights or shared experiences that could help me comprehend what transpired with my father. Thank you for your understanding. **Note:** Although English is not my first language (I am a native German speaker), I have sought assistance to clearly articulate my questions. As an EMT, I deal with emergencies but find this area outside my usual expertise.
When Should I Consult a Doctor About My Rash?
Hello everyone, I recently returned from a trip to Antigua about two weeks ago, where I experienced two bug bites on my right leg. As a 26-year-old woman weighing 140 pounds, I noticed that these bites have substantially enlarged and become quite bumpy, each measuring approximately one inch across. Unfortunately, the rash appears to be extending to other areas of my leg, and I have also developed a rash on my left leg. This new rash emerged about five days after my return home, approximately ten days post the initial bites. While I haven’t experienced any drainage, the affected areas are notably scaly and extremely itchy. Any advice would be greatly appreciated!
Question Regarding Recent Chest CT Results
At 18 years old, I underwent a chest CT scan on May 22 because my doctor suspected a pulmonary embolism, which thankfully was not the case. The results came back completely normal; both my lungs and heart appeared exactly as they should. Recently, I've been experiencing some intermittent chest pain and I'm curious about the likelihood of developing a heart or lung issue in such a brief span since the scan. Am I simply overthinking this? I have an appointment with my doctor on Monday, where I intend to discuss these pain episodes. I feel it's probably unlikely for an issue to have emerged so quickly, but I do have a family history of cardiac problems that concerns me.
