Itchy Bumps on the Back of My Arm
Hello everyone, I'm a 34-year-old man, standing at 5 feet 5 inches and weighing 150 pounds, with no prior medical conditions or medications. I don’t consume alcohol or smoke. Recently, over the past week, I have noticed the emergence of small, itchy bumps on the back of my right arm. I applied a steroid cream yesterday, but unfortunately, it exacerbated the situation and the rash has now spread, nearly engulfing my entire tricep area and extending to my shoulder. I haven’t changed any of my lotions or laundry detergents and haven’t come into contact with anything unusual lately. Does anyone have any insights on what this might be? Thank you.

It sounds like you're dealing with a concerning skin issue, and I understand how frustrating it can be to experience such discomfort. Based on your description, the small itchy bumps that have recently spread might indicate a skin condition like eczema, contact dermatitis, or folliculitis. These conditions can sometimes worsen with the use of steroid creams, especially if not used properly or for the right type of rash.
Explanation
- Eczema: This is a common inflammatory skin condition that can cause itchy, red bumps, and might worsen in response to irritants.
- Contact Dermatitis: This condition happens when your skin reacts to something it has come into contact with, even if it’s something you haven’t noticed.
- Folliculitis: An inflammation of hair follicles that can cause red bumps and itchiness.
The fact that the rash has spread after using a steroid cream suggests that it might not be the right treatment for your condition. Steroids can worsen certain types of rashes, particularly if there is an underlying irritation or infection.
Next Steps
-
Stop Using the Steroid Cream: Since it has exacerbated your condition, immediately discontinue its use.
-
Soothing Care:
- Apply a cool compress to the affected area for 10-15 minutes several times a day to help relieve itching and reduce inflammation.
- Use a fragrance-free moisturizer to keep the skin hydrated, which can provide relief.
-
Over-the-Counter Remedies: Consider using an over-the-counter antihistamine (like cetirizine or loratadine) to help reduce itching, especially if it’s interfering with your sleep.
-
Avoid Irritants: Stay away from harsh soaps, scented lotions, and any potential irritants on your skin. Keep your clothing soft and breathable.
-
Monitor: Keep an eye on the rash for signs of secondary infection (such as increased redness, warmth, or pus) or if it worsens after a few days of trying the soothing care.
If the situation does not improve within a week, or if it worsens, consider seeking professional medical advice for a more tailored treatment plan.
Please let me know if you need more information or specific guidance on any of the points mentioned.

Uncertain Symptoms and the Right Specialist to Consult
At 19 years of age and weighing 160 pounds, I find myself grappling with concerning health issues that could potentially be indicative of lymphoma. My history includes severe obsessive-compulsive disorder, which often spirals into health-related anxiety, making me question whether I am overreacting. Regardless, here are the symptoms I am currently experiencing. Over the past couple of years, I have dealt with two benign cysts in my armpit that typically resolved on their own within a few weeks. However, around four months ago, I detected a new bump in the same area, initially dismissing it as yet another cyst. To my surprise, after two months had passed, it remained unchanged in size—about the diameter of a penny—and I could slightly maneuver it without notable discomfort. I consulted a dermatologist, who prescribed a cream that I applied daily for the past two months. While the bump has since become invisible, I can still discern it upon pressing down in my armpit. Additionally, I have been noticing red blemishes on multiple areas of my skin for about three months. These spots are neither raised nor itchy, and they cause no pain. After an examination, my primary care physician identified them as petechiae and recommended I switch from ibuprofen to Tylenol, suspecting that the former, a blood thinner, might be exacerbating the issue. A subsequent blood test returned normal results. Despite this, the red spots seem to be worsening, appearing with increasing frequency. I have also observed unexplained bruising over the last couple of months. These bruises tend to be small, often manifesting in clusters ranging from two to five, yet there are instances of solitary spots as well. They appear primarily on my arms and legs and are generally hardly noticeable, causing minimal discomfort when pressed. Frequent headaches have become part of my daily experience. Their intensity varies; some are mild, while others can be so severe that they require me to rest. Typically, I feel these headaches throughout the entirety of my head, with milder variations concentrated on the right side, often accompanied by a pulsing sensation. The following two symptoms have been particularly alarming. For the past five days, whenever I touch the right side of my neck near the throat, it feels as if it has been bruised. I am unsure if I can detect a bump in that area, though there is slight sensitivity there. The left side of my neck exhibits minor tenderness, especially towards the back, but it is the right side that seems more swollen. Occasionally, it feels achy when I look down, akin to the discomfort one experiences from a misaligned sleeping position, but this sensation feels distinctly different, resembling more of a bruise. Lastly, I have experienced a quick, shooting sensation near the back of my right shoulder, just by the armpit. It manifests more as an ache that lasts less than a second, intermittently returning every few seconds for a couple of minutes, then disappearing for hours. While it is not intensely painful, it is certainly uncomfortable. Additionally, I was diagnosed with Postural Orthostatic Tachycardia Syndrome (POTS) approximately a year ago, which leaves me feeling profoundly fatigued during physical activities. I’ve always dealt with shortness of breath and a high heart rate, but I have noticed a marked increase in the severity of these symptoms recently, especially the shortness of breath. As a result, I have found myself relying more heavily on my inhaler than I previously did.
Concerns Regarding Brain MRI and Eye Flashes
Hello everyone, I'm new to this community! I’m a 28-year-old female and lately, I’ve been dealing with peculiar flashes in my vision that consistently appear in the same location—they never seem to fade away. Additionally, I experience about two severe headaches annually, which are intense but eventually subside; however, those visual disturbances persist, shifting in appearance from black to a black-and-white hue. My neurologist believes these symptoms are tied to migraines, but considering I only suffer from two headaches each year, I find it hard to comprehend. I have an MRI appointment coming up, and I’m feeling quite anxious about it. I’ve also decided against using contrast dye—not because I fear the injection itself, but due to alarming tales I’ve come across and the fact that it contains heavy metals. Is it truly essential to have the contrast? Can it reveal information that a non-contrast scan wouldn’t? I’d appreciate any insights or advice about the need for contrast in this situation. It’s worth noting that I specifically chose a facility that utilizes a T3 machine to avoid the contrast. Thank you for your help!
Concerns About Ongoing Symptoms
It all began last November when I first experienced symptoms including a mild fever, a sore throat, and a raspy voice. This illness returned the following month with the same low fever. Occasionally, I found the fever would reappear at random intervals, occurring consistently around the same time each month. After some medical evaluations, I was diagnosed with mononucleosis, alongside developing petechiae. In April, my initial symptoms began to fade, yet I noticed swollen lymph nodes in my neck. This leaves me wondering if these could merely be a lingering effect of the mono, or if they could indicate a more serious issue. I should mention that I am only 14 years old.
Popping Sound on the Outer Side of My Left Knee
I am a 45-year-old man. Back in 2016, I injured my knee, and ever since, I've experienced a distinct popping sound on the outer side of my left kneecap when I extend it outward. Alongside this, I'm grappling with a sensation of instability; at certain angles, it feels as if my knee shifts, causing excruciating pain until it eventually settles back to a normal state. Lately, I've become increasingly aware of how I move my knee, and I fear that the situation is deteriorating.
Persistent Oral Lump Inquiry
A 30-year-old woman shares her experience with a lump in her mouth that she first noticed in 2020. Although the lump hasn't disappeared completely, it has slightly decreased in size over the years. She has consulted with three ENT specialists who have either dismissed it as inconsequential or indicated they couldn't identify anything of concern. The lump does not cause any pain when touched, but she has observed an increase in its size during her current battle with strep throat, reminiscent of its initial growth back in 2020. Despite frequent visits to the dentist, she reports that none have addressed the lump during her appointments. She is contemplating whether it would be wise to seek a second opinion. Is it advisable to consult another healthcare professional regarding this issue? Thank you for your assistance.
