Red Mark on the Top of My Foot
- Age: 23 - Gender: Male - Height: 5'10" - Weight: 199 lbs - Currently taking dicyclomine and atenolol as necessary for IBS and POTS. I've noticed a peculiar red line or mark on the upper part of my right foot that has persisted for the past 2-3 days. I can't show a picture since I'm unsure how to upload one here, but I'm seeking some advice. To give a bit of background, I tend to be anxious about my health, which isn't ideal. I’ve been diagnosed with both IBS and POTS, and flare-ups from these conditions are quite distressing. A few days ago, I got out of bed and spotted this red streak on my foot. It's neither too small nor overly large—just a subtle but observable mark. When I play video games while seated, the color seems to fade to a lighter pink shade, which is a bit relieving. However, I have recently begun to feel soreness in that area. For additional context, I had been feeling unwell for over a week leading up to this mark’s appearance, spending most of that time resting in bed and only getting up for essentials. The mark has not visibly increased in size from what I can tell, though it remains present. I have been wearing compression socks throughout the day; upon removing them, I noticed the redness diminished somewhat. Does anyone have any insights or ideas regarding this situation?

A persistent red mark on your foot can stem from several causes, particularly considering your health conditions like IBS and POTS. The redness, coupled with soreness, might suggest a localized irritation, an unusual response to prolonged sitting, or even something like mild inflammation or a superficial venous issue.
Explanation:
-
Possible Causes:
- Pressure Marks: Sitting for extended periods, especially while gaming, can lead to pressure marks or redness due to restricted blood flow.
- Irritation or Inflammation: Conditions like POTS can affect blood circulation, leading to unusual skin changes in the limbs.
- Superficial Vein Issues: Compression socks might alleviate or exacerbate symptoms, depending on how your veins respond to pressure and blood flow.
- Dermatological Conditions: Although less likely, conditions like dermatitis or superficial infections could lead to red marks.
-
Symptoms You Described: The fact that the red mark seems to lighten when you wear compression socks could indicate that it's related to circulation. The soreness may suggest irritation or inflammation in the area.
Next Steps:
-
Monitor Symptoms:
- Keep an eye on the mark’s color, size, and any changes in pain or discomfort over the next few days.
-
Adjust Activity Level:
- Gradually increase your movement and avoid prolonged periods of sitting. Gentle stretching or walking may help improve circulation.
-
Evaluate Compression Socks:
- If you're consistently wearing compression socks, ensure they fit properly and are not too tight, as this could impact circulation negatively. Consider taking short breaks from them to see if it aids in symptom relief.
-
Hydration and Skin Care:
- Ensure you’re drinking enough fluids, as staying hydrated can help with circulation. Additionally, applying a gentle moisturizer to the area can help soothe any irritation.
-
Seek Further Advice if Necessary:
- If the red mark worsens, becomes painful, shows signs of swelling, or you develop any new symptoms (like fever or a significant change in discomfort), consider more prompt actions, such as consulting with a healthcare professional for a thorough evaluation.
Please take care of yourself, and remember to balance rest with gentle movement to help your overall circulation and well-being!

Experiencing Visual Confusion Upon Waking
Hello there. I’m a 37-year-old male residing in the UK. Due to my nighttime job, I often find myself asleep during the day. Recently, over the past ten days, I've been waking up sporadically and experiencing a peculiar sensation of misinterpreting the objects around my bedroom. For instance, upon waking, I have seen my headphones on the cabinet and thought they were a baby sinking into the desk. My gaming chair has frequently given me the impression of a person seated in it, while the books on my shelf often appear to be random, unfamiliar items. Just a moment ago, I awoke believing that someone was attempting to unscrew my bedroom door from the outside. There are also times when I think my sister is sitting in the room with her laptop. It’s such a bizarre experience. This seems to have started about a week ago and has recurred every single day. Occasionally, I check my phone to find out the time, only to realize that I’ve been asleep for an additional thirty minutes. I never feel frightened by these episodes; instead, I find it perplexing. Often, after staring at the strange illusion for a minute, it dawns on me that it isn’t real at all. What might be causing this phenomenon? It’s as if, upon opening my eyes, my brain instantly starts misinterpreting the first thing I see. When I thought someone was tampering with my door handle, I woke up facing directly towards it, whereas during other incidents, I’ve been oriented towards my gaming chair. Should I be concerned about these experiences? Thank you for your insights.
Could Swimmer's Ear Appear Instantly or Is There a Deeper Issue?
Background: Medical history includes conditions such as PCOS, scoliosis, major depressive disorder (MDD), generalized anxiety disorder (GAD), autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and various ongoing pain issues (diagnosis in progress). The individual also uses medications like Duloxetine, Loratadine, and Montelukast, along with a history of cannabis consumption. Situation: Each time I take a shower or engage in swimming, and water enters my ears, I experience pain almost right away. The discomfort can begin as quickly as 30 seconds after exposure and typically lasts for a few minutes. The sensation feels as if it originates deep in the ear canal and occasionally causes headaches, particularly behind my eyes. Could this be indicative of swimmer's ear, or might there be another underlying problem? Additional Context: It’s worth noting that my mother has suffered from recurrent ear infections in the past and was nearly required to have tubes placed in her ears.
Concerns Over Decreased Platelet Counts with SSRIs
I am a 20-year-old female, standing 5 feet tall, and I was diagnosed with Obsessive-Compulsive Disorder (OCD) in 2023. In January 2024, I started treatment with fluoxetine at a dosage of 20 mg, which was quickly raised to 40 mg. Following this increase, I've experienced some unusual skin symptoms, specifically tiny red dots beneath the surface that are subtle yet peculiar. Unlike the petechiae I have encountered previously, these spots seem to originate from the skin pores themselves, appearing more inflamed and noticeable than usual. I have been undergoing regular blood tests, all of which have revealed a consistently low platelet count along with a high mean platelet volume (MPV). My preliminary research suggests that this condition could point toward an increased turnover of platelets. Dealing with both OCD and health-related anxiety, I often find myself fixating on the possibility of having a serious illness such as leukemia. Although my physician has not expressed major concern regarding this issue, my platelet levels have seen a decline since September of the previous year, dropping from 146 µg/L to 131 µg/L just last week. Should I be worried about this situation? Could my medication be contributing to these changes?
Understanding the Effects of Refeeding After Starvation
Demographic Information: I am an 18-year-old individual assigned female at birth who has been undergoing testosterone therapy as part of my gender transition for approximately 15 months. At present, my height is 174 cm (5'8") and I weigh 55 kg (121 lbs). I do not take any additional medications, occasionally smoke socially about once every two weeks, and have never consulted a healthcare provider or a nutritionist regarding my eating patterns, as I only recently realized these habits were concerning. During my childhood, I faced significant neglect which led to a very limited food intake, often reduced to a single meal per day consisting mostly of fast food like burgers and fries. There were rare instances of having home-cooked meals, such as chicken or lamb served with rice or pasta. There were numerous days when I would snack sporadically—often on chips or cakes—or go without any food altogether. My bowel movements occurred only once or twice a week. This dietary pattern persisted for as long as I can remember, until last week, when I secured a stable job and decided to focus on improving my nutrition and fitness routine. Despite the inadequate nutrition, I have grown taller than average for someone assigned female at birth. However, my hands and feet appear somewhat small in comparison to my height. In terms of the effects of my testosterone treatment, I have only experienced a few anticipated changes, and these seem to be progressing much slower than expected. I have not noticed an increase in my appetite, weight gain, or alterations in fat distribution as I had hoped. I am curious to know if focusing on my nutrition alongside a workout regimen will facilitate growth at a typical pace, whether the progress will be gradual or swift, and if the outcome will skew towards gaining fat instead of muscle.
Questions Regarding Colonoscopy Results
A few months prior, I underwent a colonoscopy as part of routine screening. Thankfully, the procedure revealed no polyps, and I experienced no complications. While reviewing my results, I noted that the procedure had successfully reached the cecum and that the bowel preparation was rated as excellent. What struck me as peculiar was the phrasing in the report stating, "the colon (entire examined portion) appeared normal." This specific wording was also referenced in other parts of the document. I can't help but wonder why this distinction was made. Is there a segment of the colon that isn't routinely inspected during a standard colonoscopy? What is the purpose of including such qualifying language in the report?
