Am I suppossed to feel the same/worse/better after 1 week of abx?

I am just two weeks and 2 days in for my antibiotic treatment. The first week my neck starting being really stiff and hurting and the muscle twitching all over went into overdrive happening alot more frequent(almost non stop). The start of the second week my knee has been very painfu and weakl, sleep disturbances started back and just feeling tired. I'm not sure when things are suppose to start getting really bad. I read anywhere from a couple days to a couple of weeks.

I started herxing badly within three days of abx. I stayed sick for several months and then started to improve. It was a hellish ride.

Thanks for your replies. I haven't had a complete 100% great day in a very long time (2 years or so), so I guess I forgot how it feels... The way I look at it is... If I don't get worse, I will be able to cope with it. Some days are worse than others... My hands have been hurting more than they did before and that is probably the scariest thing for me right now. I have a 9 mo old baby and all this is a bit too much. I just pray that I won't get worse and I will be able to deal with picking her up and caring for her. My 2 older children (5 and 6) are able to do a lot of things for themselves.

On top of all this, I was in a car accident last year and still recovering from that. Just when I thought that last year was the worse of my life, Lyme came back +. Maybe next year will be better. Baby seems to thrive, but still worried she may have got it. I was on abx for 3 weeks w. her while pregnant, which obviously did not work, since I am still + for Lyme.
