So sorry you and you DH are having to go through this. I will keep you both in my prayers. It is good that he is responding to the medications and able to be up and about. I am sure having you with him while he was in isolation was a great comfort to him.
Thank you for spreading the word. Lyme disease is also a tick borne infection that is quite common in the area where I live. 5 people in a 5 mile radius of our home have had it including our youngest daughter when she was 10.
It seems that tick borne illnesses are among the most challenging to diagnose. It does help when folks like you spread the word, raising the awareness.
