Get a thermometer, they have great ones now that you can stick in your ear. See if you are running hot. I can always tell when my kids have a fever, their face is peachy and their lips get red. I have not taken mepron, ever. And just a hot face is not herxing. But do you have any sort of rash on your neck or itchy skin? Crawling skin? You could be alergic. And that could be dangerous for you.
2004 in Martha's Vineyard me and my two daughters then 11 mos and 6 all got Lyme Disease. This was only known to us because we found the tiny ticks on us and we got very ill. My dog also got lyme and he went lame.
We have fought it for 4 years to no avail.
We all got it again this summer is Texas.
I am now in treatment in Scottsdale Arizona at Envita.
