Allergic Reaction To Insect Bites Circular Rash At Site Of Tick Bite
Tick bite allergy: Hello, our immune system reacts typically after it has been exposed to a particular allergen or trigger in the past. After the first exposure, we activate one part of the immune system so that the next time we are exposed, we have developed antibodies to protect us from the exposure. So, yes you could be allergic or you are showing a possible reaction to lymes disease. See your doctor. ...Read more
Insect bites are from mosquitos, spiders, flies, ticks, and other species that use their mandibles (jaws) to attach to a person or other animal. They can then suck blood out of their "prey" and leave saliva proteins that cause itching and swelling. Other insect species, like bees, yellow jackets, wasps, hornets and fire ants actually inject venom into their prey and can not only cause localized pain and swelling, but severe, acute allergic reactions in ...Read more
Yes: Yes, but not an anaphylactic reaction to the tick bite. Usually it is only an itchy local reaction. This is a sign that you are developing an allergy to a component of the tick saliva.

Should I go to the doctor for a tick bite? Very small Tick removed 2 days ago. Red itchy rash at site of tick bite. Applied cortisone cream.
See DR: Tiny tick= risk for Lyme disease. You have a local reaction to the tick. There is good evidence for using a single dose of antibiotic, typically 200mg Doxycycline (I prefer minocycline) within 48 hrs after discovery of a deer tick to prevent Lyme. You need to be alert and ready for possible Lyme during the next 3 weeks. Unfortunately the blood tests are not reliable and sometimes the primary erytm ...Read moreSee 2 more doctor answers

My child has a weird circular rash after getting a tick bite. Is this something I should be concerned about?
Up to you: If you are allergic to the bites, then they will itch for weeks. If you scratch them, they will itch until you quit scratching them. They can cause hard bumps called nodules if you continue to rub or scratch. Also, are the fleas still around? Other bites can look like flea bites and last a long time, such as scabies and other mites. Hydrocortisone cream and oral Benadryl (diphenhydramine) will help the itch. ...Read more

What it says.: If you get stung or bitten by an insect, and you are allergic to the insect's venom or saliva, you develop an allergic reaction to the sting or bite. Usually it's just itching, redness, and swelling around the bite, but in rare cases it can evolve into anaphylactic shock which is life-threatening. Antihistamines may help mild cases, but if you have trouble breathing or other symptoms see a doctor. ...Read moreSee 1 more doctor answer

Bullseye rash?: It is common for the area immediately around the bite to be red, but if there is a clear area around that surrounded by a red ring that is a sure sign of Lyme. A single dose of doxycycline after 10 days would be worthless. ILADS (the association of Lyme specialists) recommends 200 mg of doxycycline 2x/day for 30 days. A tick bite can also cause Babesia, Bartonella, Ehrlichia & other infections. ...Read moreSee 2 more doctor answers

I have a rash on my leg. How can I tell if it is from a bite? I'm particularly concerned about a tick bite.
Discovered a rash 24-48 hours after a tick bite (size 10-15 cm). Doctor prescribed Penicillin for 10 days. No other symptoms. Is the prognosis good?
Likely: It all depends on how long the Tick was attached and if the rash was typical for erythema marginatum. Typically if there is strong suspicion for tick disease the antibiotic used is Doxycycline, unless there is an allergy. There is an excellent web site at the CDC that reviews management. Blood work is always available to look for Lyme disease. ...Read more
