Exploring Testing Options for MCAS: My Journey
I'm a 21-year-old woman who has struggled with persistent allergies for as long as I can remember. Each day, I experience a range of allergy symptoms, which tend to lessen slightly in the winter and sometimes in the fall. While medications provide some relief, they don't completely alleviate my condition. I've been diagnosed with "allergy shiners," which manifest as dark circles under my eyes, and I also suffer from dermatographism. My food allergies and intolerances seem to change quite frequently, and I often discover new ones. It appears that many of my intolerances are linked to foods high in histamine. For instance, I'm unable to consume beer, red wine, or any sourdough-based baked goods. Additionally, I’ve been diagnosed with hypermobility and am currently undergoing testing for conditions like POTS, though I already know I have a mitral valve prolapse. I'm aware that many of these issues frequently occur together. After researching, I suspect that Mast Cell Activation Syndrome (MCAS) fits my symptoms well. I'm interested in getting tested for it but feel unsure about how to proceed. Should I reach out to my doctor for a referral to an allergist and specify that I'm looking to get tested for MCAS? Do you think my symptoms point towards MCAS, or might pursuing this testing be fruitless?

It sounds like you're experiencing a complex set of symptoms that significantly affect your quality of life. Your concern about Mast Cell Activation Syndrome (MCAS) is valid, especially given your symptoms of allergies, food intolerances, and other related conditions. Testing for MCAS could potentially help confirm a diagnosis and guide your treatment options.
Main Points:
- Your symptoms, including persistent allergies, food intolerances, and dermatographism, may suggest MCAS.
- Testing for MCAS is a reasonable next step since it can clarify your condition and lead to effective management strategies.
- Reaching out to a healthcare provider for a referral to an allergist is essential.
Explanation:
MCAS can cause mast cells in the body to release histamine and other chemicals without the usual triggers, leading to a range of symptoms including allergies, gastrointestinal issues, and skin reactions. Your description of fluctuating food intolerances, as well as hypermobility and other potential connective tissue disorders, aligns with the complexities often seen in individuals with MCAS.
Given that your current medications are not fully resolving your symptoms, understanding whether you have MCAS could provide insights into better-targeted treatments, such as dietary changes, medications, or lifestyle adjustments.
Next Steps:
-
Contact Your Doctor: Schedule an appointment with your primary care provider or allergist. Clearly express your symptoms and your interest in being evaluated for MCAS. A detailed history and possibly some initial tests will likely be part of this evaluation.
-
Prepare for the Appointment: Write down your symptoms, any food intolerances, how they change with seasons, and any other conditions you have. This preparation will help your doctor understand your situation better and guide them in their evaluation.
-
Consider Allergy Testing: At the appointment, discuss the possibility of allergy skin tests or blood tests. These can help distinguish between typical allergies and those stemming from mast cell activation.
-
Monitor Your Symptoms: Keep a symptom diary leading up to your appointment. Note when symptoms occur, their severity, and any potential triggers. This information can be beneficial for your healthcare provider.
-
Educate Yourself: While waiting for your appointment, learn more about MCAS from trustworthy sources. Understanding the condition may empower you to ask informed questions and engage in your treatment plan actively.
If additional clarification or support is needed, don't hesitate to ask! Your experiences and efforts to understand your health are important.

Rash on the Dorsal Side of My Hands
A 24-year-old male, standing 5'3" and weighing 125 pounds, is not currently taking any medications. While I do not smoke, I am often exposed to secondhand smoke from those around me, and I have recently spent time in an environment where a significant amount of unpleasant smoke is produced due to casting activities. For approximately three weeks, I have been experiencing a rash on the backs of both my hands. I initially became aware of it after working on my car's engine. The rash has led to dryness and itching, and I took a photo after my shower today, highlighting the redness that has become particularly noticeable. What are some effective treatments for this condition?
Understanding Foam in Urine: When is it a Concern?
Age 24, I've observed a notable increase in the amount of foam in my urine over the past couple of years, compared to what I remember from before. About a year ago, I mentioned this to my primary care physician, who seemed somewhat dismissive of my concerns. Nonetheless, they proceeded to conduct a urinalysis, which returned normal results, indicating no elevated protein levels. I frequently undergo blood tests, and both my eGFR and creatinine levels typically fall within the normal range, although I did experience some fluctuations linked to a bout of mononucleosis a couple of years back, where my eGFR dipped near 70; it currently remains above 100. I suspect that changes in my urological function, likely from aging, are contributing to a stronger urine stream now than in my youth. The foam generally settles down after a few minutes, although occasionally it lingers longer than expected. I make a concerted effort to stay hydrated, even though I don’t always succeed, so I wonder if mild dehydration could partially account for the foaming. This concern is particularly relevant as I'm resuming strength training and planning to increase my protein consumption. I want to ensure that my kidneys are not overtaxed due to any potential underlying issues. Additionally, I have a history of taking 5 grams of creatine daily, paired with plenty of water, which makes me cautious about this, too. Is there a point at which foaming in urine is considered excessive, or does a specific threshold exist that I should be aware of?
Understanding Symptoms of Salmonella: What to Do Next
My boyfriend, who is 26, experienced a fever that peaked at approximately 99.5°F yesterday morning. Thankfully, after resting and taking NyQuil, his fever subsided by this morning. However, he has been dealing with severe abdominal pain and persistent diarrhea since last evening, which has not shown much improvement. He has been making frequent trips to the restroom, nearly every hour throughout the night and again today. While I initially thought he might be improving since the fever has decreased, I became alarmed upon noticing bright red blood in his stool and on the toilet paper after he wipes. It has been around 40 hours since the fever began, and my concern has heightened now that blood has appeared. I’ve come across some online information suggesting these symptoms might be typical for salmonella infections, and I’m uncertain whether we should seek medical attention immediately or if it’s advisable to wait another day or two to see if his condition improves. I realize that consulting a doctor as soon as possible would be the best course of action. However, he currently lacks insurance, which makes him hesitant to get checked right away. Any guidance on this matter would be greatly appreciated, thank you.
Navigating Alcohol Challenges
My partner has recently developed issues with alcohol. Over the past year, he has been consuming significant amounts—roughly two bottles of distilled spirits each week, in addition to beer. A decade ago, he struggled with inhalants and even faced near-fatal consequences, but he had maintained sobriety until he turned to drinking. He believes he has plenty of time before the effects of alcohol will manifest. How long can he continue this way before it becomes a serious problem? He is a 53-year-old male, weighing 325 pounds, standing at 5 feet 11 inches, and he is currently on medication for hypertension. Although we plan to separate later this year, it’s clear that this situation will have an impact on our three children.
Exploring MRI vs. CT Scans for Headache Evaluation
Greetings! My husband, aged 33, has been suffering from persistent headaches for the past couple of months. These headaches predominantly affect the right side of his head, specifically behind his eye, and tend to surface several times each week, particularly in the evenings. Relief is often found with extra-strength Tylenol, although there have been instances where the pain has persisted throughout the night and into the following day. The discomfort intensifies when he bends over or makes any sudden movements. In an effort to manage his symptoms, his doctor recommended magnesium supplements, which initially seemed to reduce the frequency of the headaches for a few weeks; unfortunately, the relief was only temporary as the headaches returned. He underwent blood tests, revealing that all results were normal apart from a minor elevation in his white blood cell count, which the physician indicated could potentially relate to a bacterial infection. My husband experienced a mild cold during this time, yet the doctor reassured us that these two issues were unrelated. Although he takes a multivitamin designed for men, he has maintained that routine long before these headaches began. For additional context, he sustained a moderate traumatic brain injury in his early twenties, which resulted in a blackout and a loss of about two weeks of memory. Fortunately, he has been doing well since that incident. With the resurgence of his headaches, his doctor has recommended a CT scan. However, I’m curious if opting for an MRI might be a more suitable choice. He has undergone approximately five CT scans in total due to his previous TBI and a back injury. I recall my doctor expressing concern over frequent CT scans at a young age, which has led me to seek guidance. My main inquiry is: would an MRI provide sufficient imaging quality to help determine the underlying cause of his headaches?
