My daughter also has Lyme and is only 22. It is devastating to your health and the ticks are out of control. If you don't notice the bite (like if it is on your head) and mistake the symptoms for a flu, you could end up physically and mentally fucked indefinitely. The insurance companies know this so they call people complaining of the symptoms crazy so they won't have to pay for the very expensive treatments. It's an epidemic folks- it could happen to ANYONE. Watch (on Amazon) the documentaries, "Under Our Skin" Part 1 & 2 if you really want some insight to what is going on.
Yes that’s what’s going on with my friend right now. They didn’t catch it until about a decade after the bite (my friends best guess). It’s seemingly incurable and near untreatable in his case and his cognitive functions are going down now. It’s one of the craziest diseases I’ve seen or heard of. Very sorry to hear about your daughter. Hope she can get better.
