My son got Lyme disease about 7 years ago, it was FREAKY. He was fine, then one day my friend called, my son was over her house playing with her son, and she says "what's wrong with Vinny's face?" and I'm like, "WHY?" she tells me he isn't moving a whole side of his face. So I hop in the car and race over there and talk to him, he can only move ONE side of his face. Half a smile, hard to talk, can't blink his one eye, half his face was PARALYZED. I rush him to our doctor who sends him for bloodwork, and it's Lyme. He put him on antibiotics, within 2 days his face came back to normal 100%, and he's never had a sign of it since then. BUT the doctor had said prior to that, "about half the people who develop bells palsy (what it's called when half your face goes paralyzed) do NOT recover (see Sylvester Stallone, he's got bell's palsy on half his face and it's permanant.) Doc also said many cab drivers get bell's palsy from having a window cracked and constant wind on one side of their face. Vinny got that from the Lyme disease. It effects different people in different ways. Anyway, to answer your question, you caught it early, he didn't have it for a long long time before you noticed, so the antibiotics SHOULD completely cure him. My stepmother on the other hand had it for a long time before detected, and now it's uncurable. She just gets really tired often, that's about it...
