Reactions to CT Contrast
A 28-year-old woman, weighing 250 pounds and standing at 5 feet 6 inches tall, is sharing her experiences regarding allergic reactions to contrast dye used in CT scans. Recently, she visited the emergency room due to an allergic response characterized by widespread swelling, a rash, and nausea. As a precaution, she was administered Benadryl and prednisone shortly before undergoing a CT scan three hours ago. While she felt a slight itch, her primary concern continues to be the possibility of a serious allergic reaction, reminiscent of her initial encounter. Despite the administration of pre-medications, she remains on edge at home, fearing a delayed onset of anaphylaxis. Additionally, the medical team needed to repeat the contrast dosage during the procedure because the initial imaging results were not clear enough.

It’s understandable to feel anxious after experiencing an allergic reaction to contrast dye, especially when you’ve had a severe response previously. The good news is that you proactively took Benadryl and prednisone before your recent CT scan, which can significantly reduce the likelihood of a severe allergic response.
Explanation
Your previous reaction was concerning, and it’s normal to be apprehensive about the possibility of a delayed reaction, such as anaphylaxis. Anaphylaxis can occur in some people after exposure to contrast dyes, but it is also relatively rare, especially with pre-medication. The itching and fear of additional reactions can heighten anxiety, but knowing how to monitor your symptoms can help you feel more secure.
Next Steps
-
Monitor Symptoms: Keep a close watch on any new or worsening symptoms over the next 24-48 hours, including:
- Difficulty breathing
- Swelling of the face, mouth, or throat
- Rapid or irregular heartbeat
- Severe rash or itching
-
Stay Calm and Document: If you experience minor symptoms like mild itching or a rash, try to remain calm and document when they occur and how severe they are. This information can be helpful for your healthcare provider if you need to seek further advice.
-
Hydration and Rest: Stay hydrated and rest as much as you can. This will help your body recover from the effects of the contrast dye and the pre-medications you received.
-
Emergency Action Plan: Have a plan in place. If symptoms worsen or you feel it could escalate to a serious reaction, do not hesitate to seek emergency medical help. It’s better to be cautious.
-
Follow-Up Care: Once you feel more stable, consider talking with your healthcare provider about your experiences with contrast dye. They may suggest further evaluations or alternative imaging options in the future.
Remember, it’s natural to feel anxious after a scary medical experience, so take care of yourself emotionally as well. If you continue to feel uneasy, reaching out to a medical professional for reassurance and advice is always an option.

17-Year-Old Female Experiencing Chronic Acne Scarring on Back and Arms Despite Prescription Remedies
Age: 17 Gender: Female Country of residence: United Kingdom Skin type: Dark / Black Medical background: No significant health issues Medications: Previously utilized azelaic acid and benzoyl peroxide Timeframe: Many months to years following acne resolution Greetings, I am a 17-year-old girl dealing with long-lasting scars on my back and upper arms from acne, which have not improved even after following prescribed treatments. In the past, I experienced acne primarily on my upper back, shoulders, and arms. While the active breakouts have largely ceased, I am left with noticeable dark spots and irregular skin texture. The scars I have include: • Dark brown hyperpigmentation • Certain areas appear slightly sunken • Uneven or coarse surface • No raised or keloid scars present My GP prescribed azelaic acid and benzoyl peroxide, which I applied regularly. Unfortunately, the azelaic acid did not significantly lighten the scars and seemed inadequate for the pigmentation level. Although benzoyl peroxide was effective against my active acne, it did not enhance the appearance of the scarring. The marks have been present for a considerable time and are quite stark against my skin tone. I do my best to avoid picking at my skin and maintain proper hygiene, yet the scars aren’t diminishing on their own, which is negatively impacting my self-esteem—especially when I wear sleeveless or backless outfits. Currently, I'm exploring the possibility of using retinoids like adapalene or tretinoin. However, I’m uncertain if these would be suitable or effective for treating scarring on my back and arms, particularly with my darker skin type. I would like guidance on the following questions: • Does this seem to be primarily post-inflammatory hyperpigmentation, atrophic acne scars, or possibly a combination of both? • Is azelaic acid effective for this type of scarring, or are more potent treatments generally required? • Are topical retinoids such as adapalene or tretinoin advisable for this sort of scarring? • What treatments are typically recommended for acne scars on the back and arms in individuals with darker skin tones? • Should I insist on a referral to a dermatologist, or is it better to attempt specific topical therapies first? Any insights or recommendations you could offer would be greatly appreciated.
Persistent Itching and Burning Around Neck and Scalp - Should I Keep Using Cephalexin?
Greetings, I’m a 35-year-old female. I recently developed a rash that began on the back of my neck and subsequently spread to my ears. After consulting with my physician, I was prescribed ketoconazole shampoo to address a suspected fungal rash. Despite using it diligently for four days, the condition actually aggravated, affecting my ears, the back of my neck, and my scalp more significantly. Seeking further assistance, I visited an urgent care facility where the medical staff suggested that I might be experiencing bacterial folliculitis. As a result, they prescribed cephalexin, which I am to take at a dosage of 500mg three times daily for a week. I took my first dose yesterday, yet the intense itching and burning sensations persist without improvement. Is it advisable for me to continue the medication? How long does it typically take to see improvement? Is it common to experience these symptoms alongside bacterial folliculitis? I appreciate your time and any guidance you can provide on this matter!
Concerns About Hearing Loss After Extended Earphone Use
For the past two and a half years, I have primarily relied on in-ear earphones, with the right one typically experiencing less usage—mostly for short videos or brief instances. Recently, during a singing session, I noticed something unusual. I covered one ear to monitor my pitch, and I was surprised to find that my hearing felt unclear and somewhat muffled. This was an experience I hadn’t recognized before. After conducting a few tests by alternately covering each ear, I discovered that my left ear can hear clearly and accurately, while my right ear perceives sounds as muffled, as if there’s a barrier in front of the speaker. I’m seeking advice as a 17-year-old student from Pune, India, with financial constraints that prevent me from adding stress to my parents. I’m deeply concerned whether this issue could be permanent, and if there’s any possibility of recovery. Although I can still hear sounds from my right ear when they are very close, I am unsure of the next steps. I have made the decision to discontinue using earphones starting today, but I’m wondering what additional measures I should take. Would it be advisable to pursue an audiometry test or consult an audiologist for a professional evaluation?
Experiencing Headaches and Vision Changes on One Side
Hello, I'm an 18-year-old female, and I've been on a 15mg dose of Isotretinoin for my acne treatment for about a month now. Recently, I've been feeling under the weather, dealing with a viral infection that resembles cold or flu symptoms. I've got the usual problems like nasal congestion and a throat that hurts, but I've also noticed some joint discomfort, a sense of mental cloudiness, and an unsettling change in my vision, making it appear distorted as if seen through a low-resolution lens. Additionally, when I change my position from sitting to standing, there's an intense throbbing sensation on the right side of my head, accompanied by a momentary blackout in my right eye. I must admit, my nutritional intake has not been great lately due to feeling fatigued from the cold, and this has been accompanied by headaches and a notable darkening of my vision when I stand, which is something I've never before experienced just on one side until now. I tend to get quite anxious about my health, so I'm reaching out to see if anyone else has encountered similar symptoms with a cold, or if this could be associated with the Isotretinoin I'm taking? Any insights or advice would be greatly appreciated, thank you!
