Recurring Rash on Upper Arm: Seeking Insight
Hello, I'm a 31-year-old MTF individual who stands at 176 cm and weighs around 60 kg. I don’t smoke and I take valerate estradiol in a weekly dose of 2.5 mg. I've been experiencing random rashes that seem to emerge without any warning for as long as I can recall. The rashes resemble a combination of an allergic response and a mosquito bite, even though I reside in a colder climate. It doesn't appear to be a widespread allergic reaction, as it typically manifests as a single spot, predominantly on my upper arm. These occurrences tend to happen once every month or so, with no specific triggers that I've identified—often, I’m just wearing regular clothing. The rashes can appear in any season or at any time during the day. What could this be?

It sounds like you're dealing with recurring rashes on your upper arm that resemble an allergic reaction or insect bite, and I understand this can be concerning. Let’s explore some potential causes and outline steps you can take.
Main Points
- The rashes might be due to contact dermatitis, an allergic reaction, or a form of localized urticaria (hives).
- Keeping track of symptoms and triggers is essential for identifying potential causes.
- Certain self-care strategies can help manage the symptoms effectively.
Explanation
Recurring rashes can stem from various causes. Since you notice them periodically, here are a few possibilities:
- Contact Dermatitis: This may result from contact with an irritant or allergen, even if you have not identified a specific trigger.
- Localized Urticaria: Hives can appear spontaneously and might not always have an obvious cause.
- Other Skin Conditions: Sometimes conditions like eczema or psoriasis might present in a way that resembles your description.
Since you are on valerate estradiol, it’s worth noting that hormonal changes can sometimes influence skin sensitivity or reaction patterns.
Next Steps
-
Observe Patterns: Start keeping a symptom diary to note when the rashes appear. Include details like activities, new products (soaps, detergents, lotions), and dietary changes.
-
Self-Care Practices:
- Avoid Irritants: Use gentle, unscented skin care products and wear breathable fabrics.
- Apply Cold Compresses: If a rash appears, a cold compress can help soothe irritation and reduce itching.
- Over-the-Counter Treatments: Consider antihistamines for relief if itching is significant. Creams containing hydrocortisone may also alleviate inflammation.
-
Monitor Symptoms: If the rashes worsen, become increasingly frequent, or new symptoms develop (like swelling or fever), keep track of these changes closely.
Understanding your symptoms in the context of lifestyle and any potential triggers is important. If management at home does not improve your situation over time, you may want to further evaluate with a healthcare professional. Let me know if you have questions or need specific advice on particular treatments.

Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Persistent Pain in Right Shoulder and Arm After Lifting
Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
Concerns About My Toes
Age: 30, Female Currently, I am on the lookout for a reputable podiatrist in my vicinity. However, I've encountered a perplexing issue with my foot. Just last night, I noticed a growth on the side of my toe, something entirely new to me. I maintain a nutritious diet and have a demanding job that requires me to be on my feet quite often. My footwear includes brands such as Brooks Ghost Runners, Hoka Bondi 9’s, and Nike Motiva’s, and I don’t opt for restrictive socks. I also apply Vick’s Vaporub to my feet, a practice handed down from my family, and stick with simple, non-fragrant lotions like Vanicream and CeraVe SA Cream for my skin. In addition, I am curious about the my big toenail's change in color. What might be the underlying reasons for this? Also, I have these persistent dark spots on my toes that I've struggled with since my days on the runway. Despite my efforts, nothing has succeeded in lightening or diminishing their appearance. I'm just looking to determine if there might have been a factor from the past that could have contributed to these issues. I’m not sure what else to include, but I’m open to answering any questions you might have. Thank you for your attention! Best wishes from a worried soul!
