Thanks for your concerns. In terms of cardiovascular involvement with Lyme's, the cardinal manifestation is heart block
at varying degrees, and this can easily be excluded with a resting EKG. Now, one of the complications of late Lyme's is neuropathy, and some of your symptoms are suspicious; my best advise would be to see a neurologist
to see if he believes that there is evidence of a neuropathy. If he does not, then an alternative explanation for your symptoms should be sought.
