As CD said, it is absolutely possible that the old infection has resurfaced, as that is what happens in Lyme. If it's not treated adequately the first time, I will continue to come back over and over again - or just take over your life once your body is dealing with enough other things.
I know that some of this information has already been posted, but I slept in (bad night with a dog who's in pain) and my brain is just barely awake enough to recognize when I spell something wrong!! LOL! So I'm sorry for any repeats:
As for your test results, here is the site that I use to help interpret them:
www.reocities.com/HotSprings/Oasis/6455/western-blot.txt You can go there to find supporting Pubmed articles showing what these bands represent.
An IgM result means that you have an active infection. It once was thought to mean an 'early' infection, but has since been revised. IgG means that the infection is at a later stage. The more +'s you have beside a number, the stronger the reaction.
IND means indeterminate - not negative, but not quite strong enough to be "fully positive". But it means that you reacted on those bands and should be considered, especially when they are Lyme specific bands.
A "Lyme specific band" means specific for Borrelia Burgdorferi, sensu stricto - Lyme disease in the strictest sense. There is only
one on the over 300 known strains of Lyme that is considered Bb, ss. Nothing else will turn a Lyme specific band positive other than Lyme disease.
Bands 18 & 41 (whether in IgM or IgG) are indicative of the tail of the bacteria, which can cross react with other Spirochetal bacteria such as Relapsing Fever, Pintas and Yaws, and Syphilis.
Band 31 indicates OspA (Outer Surface Protein "A") and is specific to Lyme. I know that there is some controversy to this, but there are supportive articles to this claim that it is Lyme specific and won't cross react:
www.ncbi.nlm.nih.gov/pubmed/1520966www.ncbi.nlm.nih.gov/pubmed/9440203www.ncbi.nlm.nih.gov/pubmed/8406878www.ncbi.nlm.nih.gov/pubmed/8005219www.ncbi.nlm.nih.gov/pubmed/10030131And more references can be found here:
www.reocities.com/HotSprings/Oasis/6455/western-blot.txtBand 39 indicates BmpA (Bacterial Membrane Protein "A") and is specific to Lyme. References for this can also be found in the above link.
Please be sure that you let us know how your appt goes!!
