Unexplained Bruising After Walking

7/26/2025, 8:40:26 AMMale25-34

Age 29, female, weighing 150 pounds, standing 5 feet 10 inches tall, non-smoker, drinks socially perhaps twice a year, currently taking only d-mannose and cranberry supplements, along with occasional digestive enzymes with meals. Recently, I have been noticing unexpected bruises on my legs. The largest one measured about 3.5 inches, while the others have been smaller, appearing in shades ranging from blue to purple or green, often in solid colors. I typically have no more than four visible bruises at one time. During the two weeks I was stuck at home and unable to walk due to having company, these bruises healed up completely. However, just last week, after going for three walks, bruising has returned. There is absolutely no chance these marks are from any sort of injury. I don’t keep my phone on me while walking, nor can I track my steps precisely, but my usual route covers at least a mile. It seems odd that while I was sedentary all day long, I had no bruises, but now that I've started walking again, I’m experiencing them once more. I’m curious if this is a known issue and whether it’s something I should investigate further. I've reached out on this platform previously, and I don’t have a primary care physician, which makes me reluctant to pay for an appointment just to discuss this bruising. Therefore, I’m seeking insights from here to determine if this might point to a specific condition or if I’m just uniquely prone to this issue. My mother also has a significant bruise on her foot from merely bursting a blood vessel during a foot massage, so maybe it’s a genetic predisposition where our blood vessels are unusually delicate. Who can say? Thank you for your input!

It’s understandable to feel concerned about unexplained bruising, especially when it occurs after seemingly normal activities like walking. I’ll help you unpack this situation and provide some actionable steps.

Main Points:

  • Unexplained bruising can occur for several reasons, including fragile blood vessels, increased physical activity, or potential blood clotting issues.
  • Monitoring additional symptoms will be important to determine if this is simply a unique trait or if further investigation is needed.

Explanation: Bruises happen when small blood vessels under the skin break due to impact, even minor ones that you may not notice. Some people have more delicate blood vessels, which can lead to easier bruising. This could be genetic, especially considering your mother's experience.

Since the bruises appeared after physical activity and healed while you were sedentary, it might suggest that increased movement could be contributing to the bruising. Factors like hydration, physical exertion, and perhaps even your current supplements could influence your skin's fragility.

Next Steps:

  1. Track Symptoms: Keep a record of when and where bruises appear, including their size, color, and how long they take to heal. This information can be invaluable if you decide to seek care later.

  2. Monitor for Other Symptoms: Look for any additional signs such as increased bleeding (gums, nosebleeds), changes in energy levels, or unusual fatigue. This can help you identify if there’s a larger issue at play.

  3. Hydration and Nutrition: Ensure you are well-hydrated and consuming a balanced diet rich in vitamins, especially vitamin C and K, which support skin and blood vessel health. Foods such as citrus fruits, leafy greens, and broccoli can be great additions.

  4. Gentle Movement Techniques: Since you're experiencing bruising after walks, consider starting with gentler activities (like stretching or yoga) to see if they significantly reduce bruising.

Taking these steps can help you identify patterns and determine whether further evaluation might be necessary. If bruising worsens or if you start experiencing other worrying symptoms, it is advisable to consult a healthcare professional when possible. Your health and peace of mind are important!

Concerns About Potential Blood Cancer

I’m a 21-year-old female and have been battling what seems to be a viral infection since Monday, characterized by a scratchy and sore throat. Throughout this week, I experienced episodes of night sweats on two occasions. While these episodes weren’t so severe that I had to change my clothing, I did wake up with a clammy neck and collarbone area, along with slight dampness on my chest. It’s unusual for me to sweat during a viral illness, but I considered this a reaction to the infection. To make matters worse, I’ve noticed a significant bruise on my leg. Typically, I occasionally have minor bruises with no past concerns, as my blood tests have always shown normal results. However, this particular bruise is considerably larger than any I’ve encountered before. Naturally, anxiety began to set in, making me question whether the sweating episodes were indeed linked to the virus or if they signified the onset of leukemia. Approximately three weeks back, I underwent blood tests for various other concerns, and everything came back normal—my lymphocyte count was borderline, resting right at the upper threshold, not elevated in any alarming way. Nonetheless, I’ve read about how rapidly conditions like leukemia can advance. While I don’t feel particularly fatigued or unwell, the internet can be a source of anxiety; I stumbled upon discussions of individuals who noticed just a couple of small bruises alongside a lack of additional symptoms, only to find out later they had leukemia after getting checked. My hope is that this is merely a viral infection and the bruise is incidental. However, I can’t shake the fear that something more serious might be happening. Unfortunately, I’m unable to see my doctor next week as they’re on holiday, and I’m reluctant to seek advice fearing I might come off as overly anxious or worrying too much.

A Mistake I Made Regarding Serotonin Syndrome (19F)

I recently discontinued my 10mg dose of fluoxetine about two weeks ago. Not realizing the prolonged duration of the medication's effects in the system, I took 500mg of bromelain last night. Shortly after, I began experiencing some concerning symptoms, including an elevated temperature and an increased heart rate—peaking at 70 bpm, which is much higher than my normal rate of 40 bpm. These symptoms have somewhat intensified. Should I consider going to the emergency room for what seems to be a mild case of serotonin syndrome? Is there a possibility that my condition might deteriorate further?

Unexpected Rash Appears Overnight on My Son

I have an eight-year-old son who is 4 feet tall and weighs 65 pounds. Generally, he is in good health with no ongoing medical conditions and doesn't take any medications. This morning, he woke up asking for his anti-itch cream, which we have from the Benadryl brand. Since both of us tend to attract mosquito bites during the summer, this is quite a common request. Recently, he had been treating a bee sting on his foot for a few days and just last night applied some cream to a suspected mosquito bite on the inside of his left knee. However, when I approached to help him apply it again, he exclaimed, "No, Mommy, it’s everywhere!" To my surprise, I found that his legs were covered in a rash. His legs were red with some areas raised while others were flat, and every spot seemed to be itchy. Initially, I feared it could be bed bugs, but I have my doubts for several reasons. For one, both of us have been sleeping on separate couches (which are right next to each other) throughout the week. I often sleep on the couch due to arthritis, and my son prefers to be nearby during the summer. I checked both couches and all bedding but found no evidence of bed bugs. I also laundered the couch covers just this Tuesday and I personally have no bites or any similar skin issues. He spends time at his father’s place every other week, so it’s possible that something could have happened there. However, when I picked him up, he did not have any signs of these rashes. I have scheduled an urgent care appointment for him in about an hour to get a professional opinion, but I wanted to seek advice here in the meantime. Another detail that might be relevant is that he recently treated swimmers ear with ofloxacin otic solution, but finished the drops prior to this. Thank you for any insights you can provide!

Concerns About Potential Rabies Exposure After Shared Water

Demographics: 19 year old female, measures 5 feet tall, weight around 88 pounds, from the Philippines. Main Concern: Anxiety over possible rabies exposure Duration of Worry: Today Location: Philippines Hello, I’m feeling very anxious and distressed at the moment. Earlier on, I consumed water from a glass that could have been previously used by my dog. I was under the influence of alcohol at the time, and now I’m not entirely certain about the situation. Importantly, there was no biting or scratching involved, but I am worried about the possibility of indirect contact with dog saliva. The thought frightens me, as I’ve encountered cases where rabies has resulted in death, and I’m suddenly filled with fear about my own health. My dog is healthy and behaving normally; it has received vaccinations, but I’m unsure if they are up-to-date. There have been no injuries or blood exposure. It is primarily an indoor pet. I don’t have any underlying health issues, take no medications, and I do not smoke or engage in drug use. I drink occasionally, as mentioned earlier, and I happened to be intoxicated during the incident. I’m aware that rabies is invariably fatal once symptoms present themselves, and this knowledge is causing me considerable stress. Unfortunately, I won’t be able to visit a healthcare facility until Monday since today is Saturday. I’m seeking guidance on a few points: Is it necessary to obtain the rabies vaccine in the absence of any bites or scratches? Can rabies be transmitted through shared drinking water or saliva? Furthermore, how long can I safely delay seeking treatment? Any assistance would be greatly welcomed as my anxiety levels are extremely high.

Tightness in the Scalp

Recently, I've observed that hairstyles involving tight pulls, as well as the use of headbands or hats, tend to escalate my migraines significantly. However, over the past year, I've experienced a persistent sensation of tightness and discomfort on my scalp, reminiscent of the pain felt after releasing a ponytail worn for several hours. I decided to cut my hair short and avoid styling it up to mitigate my migraine episodes, yet my scalp remains consistently tender. While the discomfort isn’t severe enough to warrant a doctor's visit, I do notice it particularly when lying down or when I scratch my scalp. I am simply intrigued by the cause behind this ongoing issue. At 20 years old, I am currently on Vyvanse and Lexapro to manage my ADHD and anxiety, as well as Qulipta for migraines. My height is approximately 5 feet 5 inches, and I weigh around 175 pounds. I refrain from putting my hair up altogether. Although I have dealt with dry scalp and dandruff issues in the past, I have successfully used products that eliminated these problems a few years back. Attempting to massage the area in hopes of relief has proven ineffective. Could the discomfort be linked to work-related stress?
