Based on your description, it is highly likely that you are experiencing urticaria, commonly known as hives.
The sudden onset over the past week suggests that this may be "acute urticaria." Most cases are triggered by food allergies, with potential allergens including seafood (especially tuna, salmon, mackerel, and sardines), shrimp, oysters, clams, fermented products (such as alcohol and stinky tofu), and nitrate-containing meats (like sausages and ham).
Additionally, peanuts and bamboo shoots (including dried bamboo shoots) are also common triggers.
It is particularly important to avoid pain relievers, as urticaria often recurs after initially subsiding.
If you experience a sensation of throat tightness or symptoms resembling a cold, it may indicate a more severe or prolonged reaction, and you should seek medical attention.

More Info

It sounds like you are experiencing a frustrating and uncomfortable skin condition characterized by unexplained itchy bumps that resemble mosquito bites. This type of skin reaction can be caused by a variety of factors, and it’s important to consider several possibilities to determine the best course of action.

Firstly, the appearance of itchy bumps can be indicative of several dermatological conditions. One common cause is urticaria, also known as hives. Urticaria can occur due to allergic reactions to food, medications, insect bites, or environmental factors such as pollen or pet dander. The bumps typically appear suddenly and can vary in size, often accompanied by intense itching. Another possibility is contact dermatitis, which occurs when the skin reacts to a substance it has come into contact with, such as soaps, lotions, or fabrics. This condition can also lead to itchy, raised bumps.

In some cases, the bumps may be related to insect bites, especially if they appear in clusters or in areas exposed to the outdoors. Additionally, conditions like eczema or psoriasis can cause similar symptoms, particularly if you have a history of these skin issues.

Given that your symptoms have persisted for a week and are causing significant discomfort, it is advisable to seek professional dermatological advice. A dermatologist can perform a thorough examination and may recommend tests, such as allergy testing or skin biopsies, to determine the underlying cause of your symptoms.
In the meantime, here are some general recommendations to help alleviate your discomfort:
1. Avoid Scratching: While it may be tempting, scratching can worsen the irritation and lead to secondary infections. Try to keep your nails short and consider wearing gloves at night if necessary.

2. Cool Compresses: Applying a cool, damp cloth to the affected areas can help soothe itching and reduce inflammation.

3. Over-the-Counter Antihistamines: Medications such as diphenhydramine (Benadryl) or cetirizine (Zyrtec) can help relieve itching and reduce the allergic response. However, consult with a healthcare provider before starting any new medication.

4. Moisturizers: Keeping your skin well-hydrated can help prevent further irritation. Look for fragrance-free and hypoallergenic moisturizers.

5. Avoid Known Irritants: If you suspect that certain products or environmental factors may be triggering your symptoms, try to avoid them until you can consult with a dermatologist.

6. Document Symptoms: Keep a record of when the bumps appear, any potential triggers (such as new foods, products, or activities), and any other symptoms you may experience. This information can be valuable for your healthcare provider.

In conclusion, while it can be distressing to deal with unexplained itchy bumps, there are various potential causes, and a dermatologist will be best equipped to diagnose and treat your condition effectively. Don’t hesitate to seek help, as timely intervention can lead to relief and a better understanding of your skin health.
