Appearance of Red Spots on Skin: A 19-Year-Old Male's Experience
I’ve noticed the emergence of red spots on various areas of my body, particularly on my arms and neck. Recently, I've been using ON Whey Isolate, and as far as I know, I don’t have any allergies. My parents believe that the whey protein might be causing these issues. What should I do? I've consulted a doctor, who suggested that these could be insect bites and provided me with a cream. However, I find it hard to believe this diagnosis since the spots keep appearing sporadically, rather than all at once. To mitigate the possibility of insect bites, I’ve even moved to a different room for sleeping.

The appearance of red spots on your skin can be concerning, especially when they change or spread. Given your recent use of whey protein, it is possible that you're experiencing a reaction related to that. However, there are also other potential causes, such as skin irritation, allergies, or other dermatological conditions.
Explanation
Red spots can result from several factors, including:
- Allergic Reactions: It's possible to develop an allergy to whey protein or other ingredients in your supplements, even if you haven't had allergies before.
- Skin Irritation: Ingredients in products such as lotions, soaps, or even detergents can cause skin irritation.
- Insect Bites: Although your doctor suggested this, it’s understandable why you may doubt the diagnosis if the spots appear sporadically.
Next Steps
To address your concerns, here are prioritized actions you can take:
-
Stop Using Whey Protein: Discontinue the use of the ON Whey Isolate for now and monitor if the spots improve over several days. If your condition improves after stopping, it’s likely linked to the supplement.
-
Track Symptoms: Keep a diary of when these spots appear, their characteristics (size, itching, etc.), and any new products or foods you try. This can help identify patterns that may indicate an allergy or irritation.
-
Observe Other Symptoms: Pay attention to any other signs such as itching, swelling, or hives, and how these spots react to things like heat or sweat.
-
Avoid Known Irritants: Be mindful of exposure to potential irritants like harsh soaps, hot water, or tight clothing that could exacerbate skin issues.
-
Consider Over-the-Counter Treatment: If the spots are itchy or uncomfortable, you may consider using an over-the-counter antihistamine or hydrocortisone cream based on your comfort level, as these can provide relief from irritation.
-
Consult a Dermatologist: If the spots persist or worsen after stopping the whey protein, it’s a good idea to see a dermatologist for a more thorough evaluation. They can provide a more definitive diagnosis and appropriate treatment.
Remember, it's essential to listen to your body and make changes accordingly. If you feel any new symptoms or have concerns about your health, don’t hesitate to take further action.

Should I Be Worried About This Insect Bite?
I'm a 21-year-old female, standing at 5 feet 10 inches and weighing 152 pounds, currently taking 100mg of sertraline. I have a bite situated just above the back of my left knee on my right leg. I took a picture of it on June 19, which I believe was five days post the initial bite that occurred on June 14; I’ve also been dealing with a lot of itching. This bite appeared among several mosquito bites, so I only realized it was distinct a few days later. Presently, it has mostly healed, but there are still remnants indicating it was there. Although I haven't experienced any unusual symptoms, the appearance of the bite is causing me some anxiety.
Persistent Chest Discomfort for Three Weeks: Potential Causes?
As a 24-year-old male, I began experiencing unusual chest tightness after returning from a hike with friends at a nearby park—the first significant hike I've tackled in several years, spanning about 2-3 miles. Initially, I didn’t pay much attention to it, but gradually, I became aware of a continuous sensation of pressure in my chest, akin to an unseen weight bearing down on me. In addition to this, I find myself occasionally coughing both at work and home, coupled with an incessant need to take deep breaths. Despite trying pain relief and antacids, that nagging pressure hasn’t subsided. I’m becoming increasingly anxious about what this may indicate and am contemplating a visit to Urgent Care or consulting with our family physician for further evaluation.

An Unexpected Transformation in My Lower Back
Something rather peculiar just occurred, and I’ll try to detail it as clearly as I can. While in front of a full-length mirror, I caught a glimpse of myself from an unusual angle—something quite new for me during this process of moving back in after water damage, where nothing is in its usual place. I noticed my shoulders appeared off, so I struck a few poses and realized my left side had a reduced range of motion. Dressed only in my underwear, I conducted some flexibility assessments and almost achieved symmetry, but my hips also seemed misaligned. My hamstrings have always been quite tight; I struggle to touch my toes without bending my knees. When I straightened my shoulders, I felt a cracking sound and something shifted in my lower back. Oddly enough, it felt pleasant, which prompted me to continue. As I bent forward to reach my toes, I was surprised by how much easier it was to lower myself; it felt as if my tailbone had liberated itself, and my hamstrings no longer ached. Straightening up, I cautiously leaned forward at the hips and discovered I was bending in a different area. I found I could hold a position between a forward lean and an upright stance, albeit not very steadily—it seemed like my muscles lacked the strength. Despite it all, there was no pain, and I retained full sensation in my legs and feet. This sparked a faint memory from my childhood, as I approach my 29th birthday. When I was about ten years old in elementary school, I experienced what began as a stomach ache. The discomfort escalated to a level where I doubled over; curling my legs provided some relief. In extreme pain, I asked to go home and awkwardly shuffled to the office to request my dad. He had a rather strict demeanor, so I wasn’t the type to make a fuss. While I awaited his arrival, I sat bent forward with my feet drawn up. The distress originated deep within my abdomen, overwhelming in intensity. When my dad arrived, he insisted I stand up; attempting to do so brought excruciating pain. He lifted me, and the agony caused tears to flow as I hobbled to the car. I don't recall anything else; we just went home. Did something significant occur back then? I certainly feel changed now. I sense that I can take deeper breaths, and I’m able to lower my shoulders and tilt my hips forward in ways I previously couldn’t. It feels as if my hips are articulated in the middle. There’s also an unusual pressure in my neck, and it's as if my mind is clearer. After some additional stretches, I noticed that when I stand on one foot, I’m not wobbling; it feels as if I'm stable, akin to standing on both feet. While seated, my posture has improved as my buttocks sit more directly under me. Again, I experience no pain… Is it possible I feel better? What just happened? For context, I have been diagnosed with ADHD, specifically the inattentive type, and have traits of autism but have not been formally diagnosed. I’ve been prescribed fluoxetine for major depressive disorder (I’ve had several hospital stays, and things have felt rather bleak) and Concerta (72 mg) for my ADHD, and I've recently noticed significant improvements in my well-being. However, I did experience serotonin syndrome after an increase from 20 mg to 40 mg of fluoxetine about 12 days ago, prompting a visit to the emergency room after inquiring with the pharmacy about my symptoms (something I was unfamiliar with). After two days, I returned to 20 mg and fortunately had no adverse reaction today. That summarizes my recent experience.
