However, there are other skin disorders that can cause rashes. These are usually not serious unless ...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?

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 was bitten by a tick in may 2008 in tennessee with a resulting bullseye rash; at this point in time, how can I tell whether I have Lyme or stari?

Persistent symptoms?: A tick bite causing a bullseye rash could be either lyme or stari. Stari tends to be self-limited without chronic symptoms. Lyme often causes ongoing fatigue, muscle/joint pains &/or neurological symptoms. If you have lyme-related symptoms get an igg & igm western blot from igenex labs, as other labs do less thorough tests. If you do not have ongoing symptoms it was probably stari.

Lyme disease: Once you have had Lyme disease you may remain seropositive (meaning your antibody test is positive) for a lifetime. You need not have had a new infection. The interpretation of the serologies can be complex and cannot be discussed here in detail. ...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

Could you get Lyme disease from a mosquito? I've been bite numerous times while sleeping and have a bullseye rash on my arm.

Could you get Lyme disease from a mosquito? I've been bite numerous times while sleeping and have a bullseye rash on my arm.

Lyme is from ticks: Mosquitoes don't transmit Lyme only ticks can do that. If you have a bulls eye rash though that could very well be Lyme. Sometimes the ticks are so unbelievably small u can't see them. It looks like u live in New England and it's summer so I consider it peak Lyme season. If the rash is bigger than 5 cm in diameter and is expanding it's probably Lyme. Show it to an MD and get some antibiotics pls! ...Read more

Which bug bites (~30 on legs) other than ticks' can cause bullseye rash 2 weeks later? I went camping and these bites never itched nor hurt.

Tick Bite: Definitely see your doctor for follow-up. CDC recommends two-step testing. First step: EIA (enzyme immunoassay). If the EIA is negative, no further testing of the specimen. If the EIA is positive or possible, then a “Western blot” test is ordered. If ill 30 days, only the IgG blot is done. A positive diagnosis requires positive for both EIA and blot ...Read more
