Sudden Eye Irritation in the Night: Could It Be Allergies?

7/28/2025, 10:30:28 PMMale25-34

At 22 years old, I experienced an unusual disturbance during the night because of severe itchiness in my left eye. Could anyone relate to this situation aside from it being allergy-related? I quickly got out of bed and headed to the bathroom, hoping to ease the discomfort by rinsing my eye with cool water. To further alleviate the irritation, I applied some eye drops. After returning to bed, I awoke to find my left eye noticeably red, a condition that persisted throughout the day. I wonder what could have triggered this reaction. Does this seem like a case of allergies to anyone? I can't shake the feeling that I might have a sensitivity to cats, especially since my feline friend had been curled up on my bed earlier that day.

It sounds like you are experiencing significant irritation in your left eye, which has persisted and is notably red. Your concern about allergies, possibly related to your cat, is valid and can indeed be a common trigger for eye irritation.

Explanation:

Sudden eye irritation, especially at night, can result from several factors, including allergies. Allergic reactions can cause symptoms such as itching, redness, and swelling. Common allergens that could lead to such reactions include pet dander (like from cats), pollen, dust mites, or even changes in environmental conditions (like dry air).

The fact that your cat was near you prior to the irritation suggests that it might be a contributing factor, especially if you have a history of allergy symptoms when around pets.

Next Steps:

  1. Avoid Direct Contact: If you suspect allergies from your cat, consider keeping him out of your bedroom, especially during the night.

  2. Cool Compresses: Apply a clean, cool, damp cloth over your closed eyelid for about 10-15 minutes to help reduce irritation and redness.

  3. Over-the-Counter Antihistamines: Consider using over-the-counter antihistamine eye drops designed for allergy relief. These can help alleviate symptoms significantly.

  4. Monitor Symptoms: Keep an eye on your symptoms for the next few days. If the redness and irritation do not improve, or if they worsen, consider documenting the details of your symptoms for future reference.

  5. Environment Considerations: Try using air purifiers or hypoallergenic bedding to reduce allergens in your living space. Regular cleaning can also help minimize pet dander and dust.

If your symptoms persist, worsen, or you develop additional symptoms like discharge or vision changes, be sure to seek further evaluation. Your comfort is important, and taking these steps can help you find relief.

Is It Possible to Develop Allergies in Adulthood?

The concept of developing allergies later in life has been on my mind. A young woman I know, who is 22 years old, had no issues being near cats in her childhood. However, as she matured, she started exhibiting allergic reactions. Additionally, she used to enjoy strawberries without any problems, but recently she experienced swelling in her mouth after consuming a handful of them. To give you a bit of context, she stands at about 156 centimeters tall and weighs around 50 kilograms. It's noteworthy that she doesn't partake in alcohol, smoking, or any recreational drugs.

Unexplained Urticaria Episodes

A 28-year-old woman, measuring 158 cm and weighing 72 kg, has been experiencing episodes of urticaria for the past month without any obvious cause. The issue began following a localized reaction to her migraine treatment, particularly the medication erenumab. Generally, she has minor reactions to this injection; however, the last two doses have led to significant flare-ups. Subsequently, she began to notice hives appearing sporadically, primarily without identifiable triggers. These episodes tend to intensify during the night but usually subside after taking cetirizine, an antihistamine. Additionally, she has known drug allergies to ciprofloxacin and penicillin. Recently, after taking cefpodoxime, she developed a rash within a few hours, although cefixime did not provoke any adverse reactions.

Concern Over Possible Botulism Exposure: Seeking Guidance

Greetings, everyone! I'm a 37-year-old male, weighing approximately 80 kilograms and standing at about 1.75 meters tall. To provide some context, I'm currently visiting a friend in another country, but I don’t have any travel health insurance. My friend had to work through the weekend and encouraged me to help myself to whatever food I found in her refrigerator. Upon arriving, I discovered some gravy that appeared and smelled fine. I decided to prepare some frozen fries in the oven while simultaneously heating the gravy in a dish, which I placed in the oven at a temperature of around 225 degrees Celsius. Following the instructions, I set a timer for 20 minutes when cooking the fries. However, when the timer went off, the fries didn’t seem fully cooked. I opted to give them an additional 10 to 15 minutes to bake (the gravy was still on the bottom, and I had completely forgotten about it). Eventually, the fries emerged from the oven, slightly overdone, but I didn't mind. Upon pulling everything out, I noticed that the gravy had begun to burn and char during the process. Afterward, I proceeded to eat the fries along with some of the gravy, which had turned into a paste-like consistency. I later called my friend to catch up and mention what I had for dinner. To my dismay, she panicked when I mentioned the gravy, informing me that it was actually 12 days old and stored in a plastic container. Now I’m left worried about my situation. How serious is this? To provide additional context: - It’s been 12 hours since I consumed the food, and I have not yet experienced any symptoms. What signs should I be vigilant for? - I heated the gravy thoroughly; it was in the oven for over 30 minutes, and the edges of the plate were charred. - Prior to this meal, I hadn't eaten anything for nearly 24 hours, so I'm hoping my stomach's acidity might be a protective factor. I didn't consume a large amount, discarding approximately half of what I had. I would greatly appreciate any advice or insights regarding this situation.

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?
