Unexplained Rash Resembles Hickey
I’m a 29-year-old female residing in the UK. I don't take any medications, I don't drink alcohol, but I do vape. Recently, I noticed a peculiar rash in front of the mirror that covers a significant area: my entire right cheek, a small section on the right side of my neck, above my right eye, spanning across my nose, and reaching the top of my left cheek, as well as a small mark on my stomach. This rash bears a striking resemblance to a hickey or possibly broken blood vessels. It is not raised, doesn’t feel warm to the touch, nor does it itch, and has only manifested within the past few hours. I am puzzled about its origin and whether it warrants a visit to a healthcare professional. Thank you for your insights!

It sounds like you're dealing with an unexpected rash that resembles a hickey and is relatively widespread on your face and body. While it's good to be cautious, let's explore what this might mean and what steps you can take.
Main Points
- The rash you describe could be due to various causes, including allergic reactions, broken blood vessels, or even a form of mild viral rash.
- Since it appeared suddenly and does not have warmth, itching, or pain, it might not be urgent, but it's important to monitor it.
Explanation
Rashes that develop suddenly can arise from several sources:
- Allergic Reactions: These can occur from skin contact with certain substances (like cosmetics, skincare products, or even food).
- Vascular Changes: Sometimes, small blood vessels can break in response to minor trauma or even without an obvious reason, leading to a bruising-like appearance.
- Infections or Viral Exposures: Certain viral infections can cause rashes that don't always itch or hurt.
Given that you don't have other concerning symptoms, this is reassuring, but it's still important to keep an eye on the situation.
Next Steps
-
Monitor the Rash: Keep an eye on how the rash changes over the next day or so. Look for signs like spreading, increased warmth, or development of itching or pain.
-
Avoid Irritants: Try to refrain from using any new skincare products or cosmetics that might irritate your skin further.
-
Note Symptoms: If you notice any additional symptoms, such as fever, fatigue, or swelling, take note of them as they may offer helpful context.
-
Hydrate and Moisturize: Ensure you’re staying hydrated and consider applying a gentle moisturizer to the area if it feels dry.
-
Consult Further if Needed: If the rash doesn’t improve after a few days, or if it worsens, consider reaching out to a healthcare professional for a thorough evaluation.
Taking these initial steps can help you manage the situation effectively. Let me know if you have any more questions or if you notice any changes!

Help with My Arm's Swelling – What's Going On?
I’m a 27-year-old male experiencing a persistent swelling on my arm that has become incredibly itchy, worsening with any contact. The area feels noticeably warm, almost as if my arm is burning. This swelling appears intermittently, and while it hasn’t significantly affected my overall well-being, the heat and discomfort can be overwhelming. Although there are no other notable symptoms accompanying it, I'm concerned about its implications. What might be the cause, and should I be worried about any potential dangers?
Concerns About Foot Discomfort
Greetings, I'm a 23-year-old male without any significant medical history, and I've recently returned to focus on improving my cardiovascular fitness through running and soccer. Approximately six weeks ago, I began to experience stiffness and mild pain in my right arch. I also observed that my right foot seemed to be pressing into my shoes more than usual, but I initially brushed it off as a minor issue. After visiting my primary care physician, I was referred to a podiatrist, who diagnosed me with early-stage plantar fasciitis. I received a program of stretching exercises and was advised to ice the area, in addition to purchasing new footwear and inserts that provided some initial relief. A couple of weeks ago, I developed shin splints as a result of pushing myself too hard during a run. The shin pain has since subsided; however, I have started noticing discomfort in my right ankle whenever I exceed walking pace. Moreover, I am experiencing discomfort in both feet—particularly my right. The arches in all my shoes feel irritating, and I also have the sensation of my toes hitting the ends of my footwear. This issue has progressively worsened over the past week. I have never encountered this kind of discomfort before. It feels as though my feet have grown significantly in size overnight, rendering most shoes uncomfortable. I'm particularly anxious about this situation since I work as a medic, and being in discomfort while walking is not an option for me. Ironically, my work boots are the most comfortable shoes I own, though even they seem to cramp my toes. I am scheduled to see both my podiatrist and a sports medicine doctor in the upcoming weeks. I would greatly appreciate any insights into what might be happening or any pertinent questions I should consider asking my healthcare providers. Thanks for your assistance!
Should I Be Concerned About Swallowing a Pill That Dropped on the Floor?
A 21-year-old woman, standing at 5 feet 3 inches, has been prescribed clarithromycin to address a toenail infection and help manage swelling. For the last five days, she's been adhering to a regimen of two tablets a day—one taken in the morning and another in the evening. However, she's feeling anxious after accidentally ingesting a tablet that briefly landed on the floor. Normally, she wouldn’t consider swallowing a pill that fell, but due to her pressing need for the medication and the fact that obtaining more was not an option, she reluctantly made the choice to take it. The tablet only touched the floor for a moment, but given the unsanitary condition of her surroundings, she hesitated. Having quickly picked it up, she decided to wash it off. In an unfortunate turn of events, it then fell into a cupcake tray that had been previously used but not yet cleaned. She rationalized that since the cupcakes came out of it, it might not be any different from consuming something that had simply been in the tray. After some wavering, she ultimately swallowed the tablet. Afterward, curiosity led her to search online, where she discovered advice suggesting that discarding such a tablet would have been advisable due to potential health risks. Now she's feeling quite anxious about whether she has harmed herself and is seeking reassurance from others who may have had a similar experience. Has anyone else found themselves in this situation and come out unscathed, or has she potentially put her health at risk?
Red Marks in the Groin Region
I'm having some trouble articulating this issue, but I have an unusual rash in my groin area. At 29 years old, I've been dealing with this for several months now. There are about ten small, round red marks that refuse to fade. They appear to be arranged in a line on either side of my groin. Initially, I considered the possibility of jock itch, but there’s absolutely no itching, and the appearance is much better than what I've seen in online images. The spots are completely flat and uniform in color, displaying a light red hue. Does anyone have any suggestions?
