Hello! Thank you for reaching out with your questions regarding urticaria (hives), its causes, symptoms, and treatment options. Let's break down your concerns one by one.

1. Understanding Urticaria: Urticaria, commonly known as hives, is characterized by raised, itchy welts on the skin. These can vary in size and can appear anywhere on the body. The condition can be acute (lasting less than six weeks) or chronic (lasting more than six weeks). Chronic urticaria can be particularly frustrating, as it often does not respond well to standard treatments and can significantly impact quality of life.
The persistent itching you are experiencing, despite treatment over the past 2-3 months, may indicate that the underlying cause of your urticaria has not been fully addressed. Common triggers for urticaria include allergens (such as certain foods, medications, or insect stings), physical stimuli (like pressure, temperature changes, or sunlight), and even stress. In some cases, chronic urticaria may be idiopathic, meaning the exact cause is unknown.
It is advisable to consult with a dermatologist or an allergist for further evaluation. They may recommend additional tests, such as allergy skin tests or blood tests, to identify potential triggers. Keeping a symptom diary can also be helpful in tracking when the hives occur and any associated activities or exposures.

2. Bruising from Insect Bites: The fact that you develop large bruises after mosquito bites is noteworthy. This could be indicative of a condition known as "bruising diathesis," which refers to an increased tendency to bruise. This could be due to various factors, including certain medications (like anticoagulants), underlying blood disorders, or even a reaction to the mosquito saliva itself.
While urticaria and bruising from insect bites are not directly related, they both indicate that your immune system is reacting to external stimuli. It would be prudent to discuss this symptom with your healthcare provider, as they may want to conduct tests to rule out any underlying conditions that could be contributing to your bruising.

3. Lifestyle Factors: You also mentioned concerns about whether lifestyle factors such as staying up late and smoking could be related to your urticaria. While there is no direct evidence linking these habits to hives, they can contribute to overall skin health and immune function. Lack of sleep can exacerbate stress and inflammation, potentially worsening skin conditions. Smoking is known to have various adverse effects on the skin, including reduced blood flow and impaired healing.
It is generally advisable to maintain a healthy lifestyle, including adequate sleep, a balanced diet, and avoiding smoking, as these can support your overall health and potentially reduce the severity of skin conditions like urticaria.

In summary, persistent urticaria can be complex and may require a thorough evaluation to identify triggers and appropriate treatment. Additionally, the bruising from insect bites warrants further investigation to ensure there are no underlying issues. Consulting with a specialist and making lifestyle adjustments can be beneficial in managing your symptoms. I hope this information helps you on your journey to better health!
