What Could Be Causing This Rash That Appeared Recently?

7/25/2025, 3:40:28 PMMale25-34

I’m a 26-year-old female. Two days ago, I experienced a stinging sensation on my chest when the water from the shower hit it, which led me to discover a V-shaped rash. As of today, the rash has spread up to my neck. I have a peculiar patch of soft skin that I've had since childhood, and the rash is visible around this area. It appears red, feels dry, itches slightly, and causes a stinging sensation, but there are no bumps present. I’ve been applying hydrocortisone cream twice daily after my showers. Occasionally, I deal with yeast infections under my breasts, but this doesn’t seem to have a fungal origin to me.

It sounds like you're dealing with a concerning rash that has developed rapidly and seems to be causing discomfort. Based on your description, the rash could be due to several factors, such as an allergic reaction, contact dermatitis, or perhaps a skin irritation exacerbated by heat or moisture. The area’s sensitivity, especially after showering, suggests it may be related to water exposure or a potential irritant.

Explanation

  • Contact Dermatitis: This can occur when your skin reacts to something it has come into contact with—like soaps, lotions, or even certain fabrics.
  • Allergic Reaction: It could also be an allergic response to a new product you’ve used, like soap or shampoo.
  • Eczema: Since you mentioned a history of soft skin in that area, this could be a case of localized eczema flaring up due to irritants or allergens.

Next Steps

  1. Discontinue New Products: If you've recently introduced any new soaps, lotions, or detergents, consider stopping their use to see if your symptoms improve.
  2. Gentle Cleansing: Use a gentle, hypoallergenic soap to cleanse the area, avoiding hot water and scrubbing, which could further irritate your skin.
  3. Moisturize: Continue applying a good quality moisturizer to keep the affected area hydrated. Look for products without fragrances or irritants.
  4. Monitor Symptoms: Keep an eye on the rash over the next few days. If it continues to spread or worsens (e.g., if you develop any blisters, increased pain, or fever), this would warrant more immediate attention.
  5. Avoid Scratching: Try not to scratch the rash, as this may lead to further irritation or infection.

If the rash does not show improvement within a week or if you have any worsening symptoms, consider seeking advice from a dermatologist. Keeping track of any changes in your symptoms will be helpful for any healthcare provider you may consult in the future. Supportive care at home can often help, but close monitoring is key. Let me know if you need further details or have any other concerns!

Managing Allergic Reactions to Bactrim: Should I Wait It Out?

I'm a 31-year-old female residing in the USA. I’ve been experiencing symptoms such as discomfort during urination and pain on one side of my back. After seeking attention at an urgent care center, the medical professionals suspected I might have a urinary tract infection or a kidney infection, with lab results still pending. They prescribed me Bactrim, instructing me to take it twice daily over the course of 14 days. Having taken my first dose roughly an hour ago, I’m now experiencing itching (without any hives) along with some redness and warmth in my face. My breathing feels normal, and I don’t have any additional concerns at this moment. Is it advisable for me to simply pause the medication until I can consult with my doctor tomorrow?

Could I Have Encountered an Allergen? 30-Year-Old Female

I'm a 30-year-old woman with known allergies to skimmed milk, shellfish, mushrooms, and penicillin. I have never required an epinephrine auto-injector because my shellfish reactions have never been serious enough to necessitate one during hospital visits. I was diagnosed with Ehlers-Danlos syndrome in my childhood and am currently undergoing examinations for ankylosing spondylitis. My medications include daily doses of omeprazole and amitriptyline, along with codeine and fexofenadine that I use as needed. Earlier today, I consumed some frozen yogurt, a treat I've enjoyed many times without any adverse reactions. However, these particular yogurts were stored next to a bag of imitation prawns I had bought last week. Unbeknownst to me, the prawns contained crab and lobster, which I only discovered after the fact. I offered the prawn bag to a friend who hasn't picked it up yet, and it remains sealed in the original packaging. Now, I find myself experiencing significant itching, primarily on the left side of my face, which has persisted for about eight hours. I've taken my prescribed fexofenadine along with some over-the-counter cetirizine, yet there's no swelling in my mouth or throat, nor do I have hoarseness—my symptoms are confined to just the left side of my face. I reached out to an out-of-hours healthcare service for advice; they suggested I wait until 9 AM to consult with a pharmacist since it’s currently 11 PM.

Should I Visit the Emergency Room After Hitting My Head?

As a 27-year-old woman, I experienced a rather unusual incident yesterday when I was struck on the forehead by two laptops. Although the impact was painful, I did not lose consciousness. I didn’t experience any significant headache afterwards either. This incident occurred around 6:30 PM, and I went to sleep a few hours later, after midnight. Despite the unfortunate event, I haven't noticed any concerning symptoms, aside from a noticeable indentation on my forehead, which I am convinced wasn't there prior to the impact. This dent has become quite apparent to me, although it doesn’t really hurt when I touch it. My husband has suggested that I seek medical attention at the emergency room, but apart from this slight deformity, I feel perfectly okay. There has been no dizziness, no nausea, and no headache—just this peculiar dent. It has now been roughly 20 hours since the incident, and I continue to feel well, though the dent persists. To give a clearer picture: the dent stretches from the upper section of my forehead down to just above my left eyebrow, forming a fairly straight line. Visually, it’s hard to detect; I can only feel it upon touching. Its depth is likely less than a quarter of an inch, probably resulting from the shape of the Chromebook that struck me. Given that I feel fine overall, is a visit to the emergency room necessary?

Should I Be Worried About Rabies Exposure?

Subject: F31, residing in the United States, height 5 feet, weight 150 pounds, currently in the 37th week of pregnancy, with no significant health issues present. The incident occurred within the last few hours. Yesterday, while preparing food, I accidentally cut my thumb with a knife, and subsequently, the bandage I applied came off. Upon returning home today, I discovered an old bag that had apparently fallen from my car—potentially earlier this week or perhaps even yesterday; I’m not exactly sure. The bag once contained about half a piece of pastry, but it must have been left outside for some time. I decided to pick it up to discard it properly, as I have concerns about littering. In our apartment area, there are numerous stray cats; most appear fairly healthy, though they are predominantly outdoor animals, which makes me apprehensive. My main worry is whether a stray cat might have licked or otherwise contaminated the pastry bag while it was outside. It was sitting in a parking spot on top of the snow. Now, with my cut thumb, I am anxious about possible rabies exposure. If any of these cats were rabid and left saliva on the bag, then it’s possible that I touched it. Unfortunately, I can’t recall if I touched the bag with my injured thumb or not. I’m uncertain about the duration the bag was outside; it may have fallen out of my car a couple of days ago or just this morning when I was getting inside. I live in an area with temperatures hovering around 30 to 40 degrees Fahrenheit, and with significant snowfall, it feels quite cold—though I’m not sure if that makes a difference. Regardless, I find myself quite worried about potential exposure. Summary: A food bag fell from my car and I picked it up to avoid littering. I have a noticeable cut on my thumb from a knife. I’m concerned that stray cats, possibly rabid, could have interacted with the bag, and I may have touched it with my injured hand, although I can't recall if I did.
