Exploring Potential Causes of Chronic Urticaria
A 35-year-old female residing in Quebec, Canada, is experiencing a perplexing case of chronic urticaria. Standing 5 feet 3 inches tall and weighing 220 pounds, she has a BMI of 38, categorizing her as overweight. For the past six months, she has been dealing with a rash that began appearing in February, initially resembling mosquito bites. Over the course of a month, one of the bumps evolved into significant swelling, or edema, on her forearm. Although she was prescribed prednisone for three weeks alongside cetirizine, the symptoms vanished during the treatment but promptly returned once she stopped taking prednisone. Since February, she has regularly taken 20mg of cetirizine three times a day. Her condition has progressively deteriorated; what began on her arms has spread alarmingly to her neck, eyelids, fingers, palms, abdomen, chest, legs, and even the soles of her feet. The rash now manifests as large, inflamed bumps that can become severely swollen, so much so that even sitting in a chair leaves marks and leads to further urticaria. She finds herself in a distressing situation where she is almost always experiencing some form of rash on her body. Resting her hands on surfaces or laying her wrists down results in immediate discomfort, and any area where her clothes come into contact with her skin triggers a flare-up of urticaria. Additional complications arise when her body temperature rises slightly, leading to intensifying symptoms. She recently started a job at a retirement home, but since then, her upper thighs have been burning and painful. Sitting down exacerbates her condition to the point where standing becomes difficult due to the compression of her muscles by the urticaria. Although she is willing to share pictures privately to illustrate her condition, she has already taken measures such as switching detergents and soaps, eliminating coffee from her diet, keeping a food diary, and engaging in meditation to manage stress. Despite her efforts, the exact cause of her symptoms remains a mystery, frustrating both her and the medical professionals involved. She expresses deep concern about her quality of life, feeling similar to the residents she assists at work, citing slowness and intense pain as major drawbacks. The visibility of her condition leads her to feel embarrassed, as she believes she appears unattractive to others. Unfortunately, local doctors remain uncertain about the underlying issues, ruling out possibilities like cellulitis, allergies, and inadequate responses to medications. She is reaching out for any insights or theories that could shed light on her situation, hoping to find relief from this debilitating condition.

I'm truly sorry to hear about the distressing condition you're experiencing with chronic urticaria. Your symptoms have a significant impact on both your physical comfort and emotional wellbeing, and it must be frustrating to not have clear answers. Chronic urticaria can be related to various triggers, and while this can make management challenging, there are steps you can take to try to improve your situation.
Main Points:
- Chronic urticaria can have a range of causes, including autoimmune issues, physical triggers (such as pressure or temperature changes), or underlying conditions like thyroid disorders.
- Symptom management is critical, especially considering how they affect your daily life and quality of life.
Explanation:
Chronic urticaria (hives) is characterized by the presence of itchy, raised welts on the skin that can vary in size and often occur in clusters. In your case, your symptoms have progressed and seem to be reacting to physical stimuli, such as pressure from sitting or clothing. It’s essential to keep in mind that this condition may not always have a clear single cause; it can be multifactorial.
Given your history with medications, you'd noticed a temporary improvement with prednisone, but symptoms returned upon cessation, which suggests there might be an underlying inflammatory or immune component at play. By keeping a food diary and eliminating potential allergens, you're already taking great initiative, but sometimes broader underlying issues may need to be considered.
Next Steps:
-
Consult a Specialist: Seek a referral to a dermatologist with expertise in chronic urticaria or an allergist who can conduct more specialized tests, such as a skin biopsy or blood tests for autoimmune conditions.
-
Consider Medication Adjustments:
- Discuss with your healthcare provider about options beyond cetirizine, like higher doses of antihistamines, or second-line treatments such as omalizumab (Xolair), which has shown effectiveness for chronic urticaria.
- It may be beneficial to review the recent use of medications like prednisone for potential longer-term management plans.
-
Identify Physical Triggers:
- Keep an ongoing diary of your symptoms, particularly in relation to physical activities or environmental changes (like temperature shifts or pressure points). This can help identify specific triggers that you may not have recognized yet.
- Since you noted changes tied to temperature increases, consider cooling measures for flare-ups, such as cold compresses or cooling pads.
-
Lifestyle Modifications:
- As you continue to engage in stress-reducing activities like meditation, consider exploring additional relaxation techniques like yoga or gentle stretching, which may also relieve stress and potentially improve overall skin comfort.
- Continue avoiding known irritants and try to wear soft, loose-fitting clothing to minimize friction and discomfort on inflamed areas.
-
Support Networks:
- Seek support groups or online communities where you can connect with others experiencing similar conditions. This can provide not only emotional support but also potential tips for managing symptoms from those who understand your situation.
I encourage you to be patient with the process of finding relief, as chronic conditions often require time to understand and manage effectively. Please remember that you're not alone in this, and there are resources and communities available to help you through it. Let me know if you need further details or have other questions.

Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Healing Progress Post-GBS: Toe Concerns
I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
