Welcome Little Bear!!!
So sorry for all you've endured and continue to endure!! ((Hugs))
Yes, as others have mentioned, we often feel worse....much worse....during treatment.
The reason being the toxins released by the bacteria as they die.
While it's great you are doing sauna and foot soaks, adding many more things to your detox protocol will only help. There are great suggestions in the "New to Lyme" thread at the top of the forum including a link to this site:

Best wishes to you moving forward!! Hope you'll visit often and avail yourself of the support and knowledge that is quite prevalent on this forum.
