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. It is common for the bite site to itch for several months. It is not a sign of infection. This can set you up to develop other allergies. For more information check out the "healthguide" " delayed meat allergy...". ...Read more

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 more
My husband has a weird rash around a bug bite. It could be a tick bite I am unsure. Should I be worried?
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.

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 more
I have the bullseye rash around a tick bite but no other symptoms of Lyme disease. Should i still get a test done?
Get Rx & blood test!: A bullseye rash around a tick bite is considered proof of lyme disease.If you do not have symptoms yet, you almost certainly will over time. It takes time for a blood test to turn positive & you should not wait for this; the earlier you start treatment the better the outcome.Many lyme specialists advise Doxycycline 200 mg 2x/day for a month to be safe.Also get tested for co-infections like babesia. ...Read more
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?
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
3-28 days: A tick bite can transmit the organism that causes lyme, which can lead to a characteristic circular rash around the tick bite, beginning a few days to a few weeks after the exposure. Early treatment of Lyme disease with antibiotics is important to prevent complications of late Lyme disease. ...Read more
I have a bullseye rash around a tick bite but do not have any other symptoms of Lyme disease. Do I need to get a blood test?
Not just Lyme: Avoid being "lyme-centric"! depending on geography, there are several other tick borne diseases ( e.g. Anaplasmosis, babesia, human monocytic or granulocytic erlichiosis) that co-infects with lyme (caused by b. Burgdorferi), or else , the diagnosis is something other than lyme (eg. Relapsing fever caused by b. Hermsii & southern tick -associated rash illness [stari] caused by a diffferent tick. ...Read more
Yes: Many disesases are spread by tick bites. The lyme disease rash of erythema migrans typically causes a large "bulls eye" or annular rash at the bite site. Southern tick associated rash illness has a similar rash but its smaller and commonly on the trunk. You can also get a bacterial superinfection of a tick bite. See your doctor for proper diagnosis and treatment. ...Read more

Lyme: A rash around a tick bite, especially if its a target like red rash and you live in part of the country where lyme is common, is essentially diagnostic of infection with lyme disease. A relatively short course of oral antibiotics (doxycycline is usually best) will easily get rid of this. ...Read more
What specific test to request to diagnosis late stage Lyme and/or co-infections, untreated tick bite rash 6 years ago? Can these tests be ordered by my PCP?
About two months ago I got a tick bite between my toes. It still has flareups of itchiness at random intervals (days to weeks between). It turns red when scratched, but there is no rash or other known symptoms. Could it be scarred tissue?
Just a thought:
but the area between the toes COLLECTS DIRT like a MAGNET...clean the area daily with a soft Q TIP (Cotton swab) You may want to also swab withan OTC (Over the Counter) cortisone cream! Try this for a week-10 days ..if this does not resolve your problem you need a "hand on" examination ....start with your PCP or Family Physician!
Hope this helps
