I had a look at the Wikipedia page for parvovirus B19, but I don't see many similarities to what chronic Lyme sufferers say; they generally complain of chronic pain that lasts for several months or years, not just weeks. Lyme sufferers also generally claim to have been bitten by a tick, and had them characteristic target rash, rather than a "slapped face" rash. Honestly not sure what would make you think "Lyme" with the symptoms you describe.
