The first test I had showed 2 bands of 5 positive and was told I was negative for Lyme. I had another after 5 years of not knowing why I was so sick which was positive. It was the standard test. Can't remember the name.
Not just depressed as most of the doctors told me. Followed with spinal fluid test which showed positive for Central Nervous System Lyme. I believe that was the cause of all the manifestations of diseases that followed.
From all the research I have read, Long Covid produces the same results which is why I follow this tread. You may or may not have Lyme but Covid could be causing your symptoms and the same treatments may be helpful. I know how frustrating, scary and difficult all this is. I have suffered for 15 years now. Just keep trying to find answers as you are now doing.
