About a year ago my 28 year old son was driving to work and noticed a whole face numbness. Since then he has had repeated dizziness, headaches, numbness heart racing etc. He has been to so many doctors who have done heart and neurological test. His insurance changed and he is seeing a new internist on Monday. He is not depressed or having anxiety from what he is telling me. His doctors have said that they can t find out why. He was in the ER a month ago because he thought he was having a heart attack. The symptoms are usually worse at night. They did put him on a low dose synthroid last year but his uptake levels are fine when they check him. At this point I am very concerned. He lives in Charlotte, NC. I was wondering if he should be checked for Lyme Disease?
