It sounds like you're dealing with a bothersome rash on your back that has been persistent for a week. Itching and discomfort can be very frustrating, and it's important to understand potential causes and next steps.
Main Points:
- The rash may be due to several potential causes such as irritant contact dermatitis, allergic reactions, or other skin conditions.
- Self-care measures can help relieve symptoms while you monitor the rash.
Explanation: Rashes can occur for many reasons, including exposure to irritants (like soaps or laundry detergents), skin infections, or even conditions like eczema. It’s also possible that recent weather changes or humidity levels in the Pacific Northwest could have contributed to skin reactions. Typically, these types of rashes can resolve with proper care but should be monitored for any worsening.
Next Steps:
-
Keep the Area Clean and Dry: Gently wash the affected area with mild soap and water, and pat it dry. Avoid scrubbing, which can aggravate the rash.
-
Apply Moisturizer: Use a fragrance-free moisturizer to help keep your skin hydrated. This can soothe the itching.
-
Avoid itches triggers: Refrain from using products on your skin that may irritate it further, such as heavily scented lotions or soaps.
-
Consider Over-the-Counter Remedies: You may find relief with antihistamine creams (like hydrocortisone) or oral antihistamines (like diphenhydramine) to reduce itching. Follow the instructions on the packaging.
-
Monitor the Rash: Keep an eye on the rash over the next few days. Note any changes or if it begins to spread, become painful, or if you notice any additional symptoms like fever or swelling.
-
Adjust Lifestyle Factors: Consider whether the use of vaping products might be contributing to skin sensitivity. Reducing exposure to potential irritants or allergens can be beneficial.
If the rash does not improve within a week or worsens, or if you develop systemic symptoms (like fever or swelling), it would be best to revisit the situation and seek help from a healthcare professional. Please feel free to share any updates or additional questions you might have!

Severe Limitations Due to Dysautonomia Following Cancer Treatments
Hello. I'm a 38-year-old woman who completed her second round of cancer treatment in March. Over the years, I've encountered various unexplained medical issues (which you can find summarized at the end). My treatment journey was briefly interrupted because my mother was receiving hospice care. However, after resuming immunotherapy last September, I now find myself nearly confined to my bed. Whenever I attempt to stand up, I experience significant nausea (which often leads to vomiting or dry heaving, along with a runny nose and hot flashes). This reaction occurs reliably if I remain upright for more than 1 to 3 minutes. On some days, I manage to cope a little better, but many other days are quite challenging. My overall quality of life has greatly decreased, largely due to these severe episodes which often leave me feeling unwell for the remainder of the day. Additionally, I've noticed a significant increase in my heart rate, particularly in the mornings and during hormonal changes. I have been prescribed odanestron and olanzapine; however, their effect is minimal and only allows me to maintain an upright position for a slightly longer period. Before my cancer diagnosis, I experienced widespread pain and petit mal seizures. In my childhood, I dealt with several conditions, including: - Suspected long QT syndrome (originally SVT, but it evolved over time) - A lazy eye - Scoliosis - Inward-turned hips The vomiting episodes have compelled me to keep vomit bags strategically placed throughout my home, in my purse, and even in our vehicles. Currently, I've reached a point where I can only manage the essential tasks, such as visiting the restroom, and I’m largely unable to leave the house or navigate effectively within it. If relevant, I should mention that I've developed a patchy rash on my lower legs (from the knees downward) since starting immunotherapy. Dysautonomia has come up in conversations regarding my condition; prior to this, there was a suspicion of paraneoplastic syndrome. I'm reaching out in hopes of receiving some advice or recommendations. My limitations have led to my approval for disabled placards, and I've even applied for disability assistance, as standing has become an extreme challenge for me.
Issues with Gag Reflex and Nausea
A 20-year-old assigned female at birth has been experiencing recurrent gagging and vomiting episodes for the past two years, a situation that seemed to coincide with the onset of a new job, suggesting potential stress-related influences. This individual frequently encounters gagging or dry heaving when transitioning from a sitting to a standing position, and on occasion, they may even spit up. The symptoms appear to intensify during allergy season or when there is excess phlegm present in the throat. Following meals, the individual struggles with nausea, particularly when trying to change positions, such as sitting up slightly, standing, or taking short walks. Even after several hours post-meal, standing too quickly can trigger gagging or vomiting. While the person does have pre-existing heart concerns, they report no accompanying dizziness, and notably, they usually have a high tolerance for unpleasant stimuli, making these episodes particularly perplexing. An upcoming appointment with a doctor is anticipated, as this individual hopes to gain clarity about their symptoms—an endeavor that previous online searches have not illuminated.
Concerns About Potential GI Bleeding?
Profile: Age 22, Weight 180 lbs. For the past couple of days, I've experienced bowel movements that were black and liquid, though they were not tar-like in appearance, rather just a thin consistency. I have not consumed anything unusual or taken any supplements that I'm aware of that would explain this change. My most recent stool was normal in texture, and I have not experienced any accompanying symptoms like lightheadedness or nausea. Recently, my diet included Mexican cuisine and spaghetti, along with consuming a bottle of wine. Although I haven't had the unusual black stools for two days, my friends continue to recommend that I seek medical attention. It's worth mentioning that my grandmother had colon cancer, though I'm uncertain if there's a hereditary aspect to this. I have a history of bulimia and alcohol misuse in the past, but I've been stable lately and haven't encountered any ongoing health issues related to these experiences. Given that my last stool was typical and I do not feel fatigued, should I still consider visiting a hospital? I would like to point out that I am a financially-strapped college student with limited health insurance, so I intend to avoid the hospital unless it's truly essential.
Seeking Guidance on Unexplained Nerve Pain and Blood Donation Aftereffects
I am a 29-year-old woman, standing 5 feet 4 inches tall and weighing 160 pounds, with no known chronic health issues. My daily regimen includes a slow-release iron supplement and 5 grams of creatine. Recently, my diet has been fairly consistent, consisting of stew and rice last week, followed by three days of pasta with a red meat sauce, and currently, I am having a mix of rice, meat, and vegetables. Although I’ve been attempting to stay hydrated, I suspect I could be doing better in that regard. I have a familial history of diabetes and cancer, which adds some concern. For the past few weeks, I’ve experienced persistent nerve pain in my right foot. Initially starting in the lowest joint of my big toe, the discomfort has begun to radiate to the ball of my foot and occasionally up to my ankle and shin. This painful sensation has become quite frequent, ranging between a 2 to 5 on the pain scale. Additionally, I completed a power red blood donation last Saturday, and unfortunately, I had an adverse reaction to the citrate used during the procedure. For three days following the donation, I felt unwell, experiencing symptoms such as chest flutters reminiscent of panic attacks, headaches upon standing, fatigue, and intermittent chest discomfort. Given these issues, I am uncertain whether I should consult a general care physician or if it would be more appropriate to seek out a podiatrist, considering that my additional symptoms may be linked to the donation process. What would be the best course of action?
Dealing with Tendinitis in the Left Thumb and Wrist: Should I Rest or Keep Moving?
As an active 66-year-old man involved in various sports, I've recently embraced racquet sports, even though I'm right-handed. Over the summer, my activity level decreased, and I've begun to experience discomfort in my left thumb and wrist, which has lasted for two months now. The intensity of the pain is manageable, and I've been cautiously moving my thumb and wrist; however, the discomfort has not improved. In an effort to alleviate the pain, I've started wearing a wrist splint, particularly during the night, yet my symptoms have worsened. This leaves me uncertain about the best course of action—should I opt for complete rest or incorporate gentle movements? It's been a while since I last visited the gym, but I'm contemplating a session with light weights tomorrow to see if it helps.
