Very good advice.
I was speaking with a woman at a hospital appointment ,whose 4 yr old daughter showed all the signs of lyme. (& she knew her daughter had been bit two months before the symptoms showed. )
Little girl tested negative for iLyme. The Mom didn't give up. After a year of her daughter getting worse with no help to discover what was wrong ( with her constant pushing the professionals) ,she heard of a Dr who specialized in Lyme D in Ottawa Canada. He treated her daughter aggressively & she is doing well. She Will always have some problems that can not be reversed but this Dr has stopped the progression of the disease.
Don’t give up. Go online & look for a specialist with good results.
