Insect bites


Hello, doctor.
I would like to ask about an outdoor activity I participated in on Saturday where I was bitten by mosquitoes.
On Monday, in addition to itching, I noticed swelling on my face, particularly around my eyes.
Starting Monday night, I began to experience itching on my back and slight discomfort in my throat (a sensation of something being stuck when swallowing).
Should I see a dermatologist? Thank you for taking the time to reply!

More Info


When it comes to mosquito bites, most people experience mild symptoms such as itching, redness, and swelling at the site of the bite. However, in some cases, individuals may develop more severe reactions, especially if they are allergic to mosquito saliva or if they have been bitten multiple times. Your symptoms, including facial swelling, particularly around the eyes, and the sensation of a foreign body in your throat, suggest that you may be experiencing an allergic reaction to the mosquito bites.

In general, it is advisable to monitor your symptoms closely. If the swelling continues to worsen, or if you experience difficulty breathing, wheezing, or significant swelling in other areas of your body, you should seek immediate medical attention, as these could be signs of a more serious allergic reaction known as anaphylaxis.
For your current situation, seeing a dermatologist or an allergist would be a good idea, especially since you are experiencing facial swelling and discomfort in your throat. A dermatologist can assess the extent of your reaction and recommend appropriate treatments, which may include antihistamines to alleviate itching and swelling, or corticosteroids to reduce inflammation.
In addition to seeking medical advice, there are some self-care measures you can take to alleviate your symptoms. Applying a cold compress to the affected areas can help reduce swelling and provide relief from itching. Over-the-counter antihistamines, such as diphenhydramine (Benadryl) or cetirizine (Zyrtec), can also help manage allergic reactions and reduce itching.
It is also important to avoid scratching the bites, as this can lead to secondary infections. Keeping the area clean and applying topical treatments, such as hydrocortisone cream, may help soothe the skin. If you notice any signs of infection, such as increased redness, warmth, or pus, you should seek medical attention promptly.

In summary, while many mosquito bites can be managed at home, your symptoms indicate that it would be prudent to consult a dermatologist. They can provide a thorough evaluation and tailored treatment plan based on your specific symptoms and medical history. Remember to keep an eye on your symptoms and seek immediate care if you experience any severe reactions.
