Can there be anything I can do to relieve chest and joint pain from lyme's disease?

Yes! Take an NSAID like Naproxen and follow a course of Doxycycline 100mg bid or clarythromycin 500mg bid for one month!
NSAID. An NSAID (non-steroidal anti-inflammatory drug) like Naproxen or Ibuprofen is available over the counter (take with meals please) and will held with the pains. If lyme's disease is confirmed an antibiotic is needed which you should see a doctor to prescribe.
