It is very typical in the course of Lyme Disease, to become extremely ill with the symptoms being caused by the activity of the immune system, then after a period, to seemingly become much better and even to think that one is cured. This is false as the disease process contines, though it might get knocked back through a course of antibiotics for some other infection. The improvement is due to the lessening activity of the immune system which is now being fooled by the bacteria. The bacteria mimics the DNA of the host so that it is relatively left alone to invade the whole system. This is the process which went on with me, until 10 years later when I discovered the awful truth. Western Blot blood tests for Lyme are not reliable.
