Itchy Bumps After Running
Greetings everyone! A few months back, I began noticing some bothersome itchy welts appearing on my thighs, chest, stomach, back, and upper arms. Typically, I only experience about four or five at any given time. These welts are extremely itchy and tend to arise exclusively after a run or some form of physical exercise. They usually disappear within an hour, only for others to emerge, lasting a day or two post-workout. Occasionally, they even show up during the night, disturbing my sleep due to their itchiness. I've looked into this issue and found that many of the images I've seen resemble rashes, but mine seem to be more like isolated hives—just one or two on my chest, stomach, and maybe one on my thighs and arms. At 30 years old, I have maintained an active lifestyle, primarily through running. Has anyone else dealt with something similar? It’s quite frustrating!

It sounds like you are experiencing itchy welts, resembling hives, that appear after running or exercising. This condition is likely related to exercise-induced urticaria, which is a type of allergic reaction triggered by physical activity. While it’s understandable that this situation is frustrating, there are effective ways to manage your symptoms.
Understanding Your Symptoms:
- Hives: These itchy welts can develop due to increased body temperature, sweat, or even clothing friction during physical activity. It's your body's way of reacting to the changes during exercise.
- Duration & Timing: The fact that these welts appear during and shortly after your runs and can sometimes disrupt your sleep points to a consistent pattern, which is helpful to note.
Next Steps:
-
Cool Down and Shock: After your workout, take a cool shower or use a cold compress on the affected areas to help reduce itching and inflammation.
-
Hydration: Ensure you’re well-hydrated, as dehydration can sometimes exacerbate skin issues. Drink plenty of water before, during, and after your workouts.
-
Clothing Choices: Wear moisture-wicking and loose-fitting clothing while exercising to limit friction and irritation on your skin.
-
Antihistamines: Consider taking an over-the-counter antihistamine like cetirizine or loratadine before your workouts to help prevent the hives. Discuss this option with your pharmacist for appropriate dosing and potential interactions with any other medications you may be taking.
-
Monitor Triggers: Keep a diary of your workouts, including intensity, duration, and conditions (like heat and humidity) to help identify specific patterns that may be triggering your reactions. This information can be valuable for personalizing your management strategies.
-
Avoid Hot Showers: After exercise, try to avoid hot showers, as heat can aggravate hives. Instead, opt for lukewarm water.
If your symptoms persist or worsen despite these measures, or if you develop new symptoms like difficulty breathing or swelling beyond the welts, it’s important to seek medical advice for potential underlying conditions. But for now, implementing these strategies should help alleviate your discomfort during and after your runs. Let me know if you have any further questions!

Week-long Battle with Chest Pain
Greetings! I'm a 35-year-old female, 5 feet 4 inches in height and weighing 150 pounds. On Presidents' Day 2026, I suffered a fall while skiing, which left me with considerable discomfort in my right knee. The pain was quite sharp and pulsating but started to diminish after about a week. However, shortly after that, I began to endure severe chest discomfort. The sensation in my chest is tight and unrelenting, radiating from the center towards the right side. Additionally, I've been experiencing sporadic abdominal pain, yet the chest distress remains a constant issue. My appetite has diminished and sleep has become difficult due to the pain. I also feel a swirling pain that travels around my right shoulder blade and comes and goes. Nevertheless, the pressure in my chest is persistent and overwhelming. On Sunday, March 1, 2026, I began to feel discomfort in my neck, as if I had slept awkwardly, which has impeded my movement. The following day, I went to the emergency room where I was subjected to multiple tests related to my chest, all of which returned normal results. By Tuesday, March 3, 2026, my neck was feeling somewhat improved, but the chest pain escalated, moving from the left side to the right. Later that day, the neck discomfort resurfaced to the point where I struggle to move, leaving me uncertain about how to handle the situation. Does anyone have suggestions for dealing with this ongoing pain? Any advice would be greatly appreciated!
Sore Bump Inside Ear
I am a 35-year-old woman with a generally good state of health, currently taking Zoloft and Trazodone. Recently, I began experiencing discomfort within my ear starting two days ago. The area is quite tender, making it difficult for me to rest on that side. Additionally, I observed a small white bump, resembling a pimple, both yesterday and this morning. I have not touched it and even applied pimple patches in hopes of managing it. I'm uncertain whether this issue necessitates a visit to a healthcare provider. My insurance plan is quite poor, which means seeking medical advice could result in hefty out-of-pocket expenses. I'm wondering if this might simply be an oddly located pimple or if it could indicate a need for antibiotics.
Struggling with Shortness of Breath and Chest Discomfort for Over Three Years
I'm a 28-year-old female, weighing 130 pounds, and I have been enduring shortness of breath accompanied by tightness on the right side of my chest for the past three and a half years without any clear diagnosis. This condition has a profound impact on my everyday life, and I am in search of some guidance. To provide context, I enjoyed great health in 2022; I was running daily and hiking several times a week until suddenly, I began experiencing shortness of breath that hasn't ceased since. Although I have a history of asthma that dates back to age three, recent pulmonary function tests have indicated that my asthma is mild, and steroid inhalers have proven ineffective. The tightness and breathlessness are localized strictly on my right side. It feels as though my right lung is constricted, with a sensation of pressure in my chest. At times, I also experience a deep, itchy feeling in my right lung area and along the right side of my neck. Additionally, I have a faint wheeze whenever I exhale. This shortness of breath manifests both during physical activity and at rest. Along with these symptoms, I frequently notice my cheeks turning bright red, experience occasional pain in my right shoulder and collarbone, suffer from profound fatigue that necessitates daily naps despite sleeping over eight hours at night, and face episodes of dizziness and confusion that worsen when I stand for prolonged periods. Heat intolerance is another troubling symptom, coupled with occasional swallowing difficulties and throat pain during flare-ups, swollen glands exclusively on the right side of my throat, eye oil gland dysfunction leading to dry eyes, and persistent hives on my neck and back that do not improve with antihistamines. Several of my healthcare providers have suggested the possibility of an autoimmune disorder like lupus, but unfortunately, rheumatologists in my area can deny referrals, which is quite disheartening. I have also noted a consistently low positive ANA titer (1:80, with fine speckled and homogenous patterns). Recently, I have been experiencing a significant flare that seems unending. Although I had begun to see slight improvement over the previous year and was able to resume exercising—including running a half marathon—my situation worsened after contracting a mild viral infection last September. Since then, I've been struggling; I now find myself coughing after light runs and my heart rate skyrockets to 180-190 bpm with minimal effort—numbers I hadn't seen before when I could maintain a heart rate of around 160 bpm. Notably, a recent EKG at my cardiologist’s appointment indicated possible enlargement of the left atrium. From my research, this can often be a false finding, but I felt it necessary to mention. To provide further background, I have suffered from migraines since I was twelve, have had mild asthma since childhood, and have dealt with Raynaud's phenomenon since I was young. I also suspect I may have endometriosis, given my history of pelvic pain, exceptionally heavy menstrual cycles, and imaging studies since my teen years showing potential endometriomas and chocolate cysts. Regarding my family health history, my father has multiple serious conditions, including atrial fibrillation, pulmonary hypertension, congestive heart failure, severe spinal stenosis and neuropathy, and he has suffered a pulmonary embolism leading to cardiac arrest during surgery. Thank you for taking the time to read my lengthy account. After enduring these issues for 3.5 years, I'm feeling quite overwhelmed and would appreciate any direction or insights you may have to offer.
Chronic Neck Discomfort When Rotating Head
At 34 years of age, standing 5'9" and weighing 230 lbs, I encountered a troubling situation a fortnight ago. During a particularly demanding work shift, I was engaged in lifting heavy pallets into a dumpster. Although the task was physically taxing, I didn't feel any immediate pain at the time. That evening, I joined friends in a hot tub for roughly three hours; however, I struggled to find a comfortable position which ultimately led me to awkwardly float with my head above the water for an extended duration. Upon waking the next day, I was met with significant discomfort in my neck, particularly when attempting to turn my head from left to right. I suspected that the strain stemmed from maintaining that awkward posture for so long. Now, two weeks later, the neck discomfort remains persistent, and I fear it might be worsening. I've attempted to relieve the pain through self-massage and testing my neck's range of motion by gently rotating it, although these movements are painful. To avoid exacerbating the issue, I spent several days minimizing neck activity, which yielded minor improvements. Still, after about three days, my impatience got the better of me, and I resumed normal movements, as turning my whole body felt cumbersome. Currently, the pain is quite pronounced, intermittently disrupting my sleep and presenting itself as a throbbing, aching sensation. I can't help but feel that if this were a more severe condition, such as meningitis, I would be exhibiting additional symptoms by now. Nevertheless, the intensity seems more severe than merely a typical muscle strain, particularly because the discomfort impacts both lateral sides of my neck—specifically the upper neck muscles where they connect to the base of my skull. I welcome any insights regarding what this condition might be or recommendations for initial treatment steps. Thank you!
Is It Possible for Musculoskeletal Pain to Persist for Two Years?
At 38 years old, I consulted my doctor in 2024 about persistent discomfort in my right rib area. Initially, my physician suspected gallstones, prompting an ultrasound. However, that examination revealed an adrenal mass, necessitating a subsequent CT scan that diagnosed a 2.6 cm adrenal adenoma, which is benign. Fortunately, all other findings from the CT scan were normal, leading my doctor to conclude that the pain is likely musculoskeletal in nature. I experience discomfort daily, with the intensity peaking during the evening hours and being relatively manageable in the morning. This pain seems independent of my eating habits. The area around my lower right ribs is extremely sensitive to touch, creating a sensation akin to being bruised and inflamed. When I bend, it feels as though there’s a heavy weight pressing underneath my right ribs. To alleviate the pain, I have been taking co-codamol consistently, yet it offers little relief. I find myself questioning whether this discomfort will ever subside. It’s challenging; I feel miserable and harbor concerns that the issue might extend beyond mere muscular pain, worrying that there could be something more serious going on with my health.
