Here is a lyme and coinfection symptom chart.
www.lyme-symptoms.com/LymeCoinfectionChart.html If you do a "find" search for sweat, you will see that there are 4 infections that come up with sweat as their symptom. So many of the symptoms overlap each other. It is very difficult to say.
I think my sweating was just lyme, but who knows? I was just happy when it was treated and gone.
Be patient and stick with the treatment.
However, your conclusion that this all started with the addition of a new drug is a tattletale sign for herxing. That is a sure sign that more detoxing needs to be done or, if the symptom is too intense, you need to back down on the meds so you don't hurt your body.
