I also know someone that was treated for Lyme for years despite having negative test results. She was diagnosed with MG after a doctor noticed her drooping eyelids and sent her to a neurologist where she tested positive for MG. I know another person who insists she has Lyme despite negative test results and has all the symptoms of MG but refuses to be tested for it. The medications she takes for Lyme are not effective and she is suffering terribly.
