Physical findings in patients with early disseminated disease are as follows:
Erythema migrans, single or multiple lesions
Tender adenopathy (regional or generalized)
Conjunctivitis (uncommon, never prominent)
Carditis (usually manifests as heart block)
Meningismus as a sign of aseptic meningitis
Cranioneuropathy, especially cranial nerve VII and Bell palsy (peripheral seventh nerve palsy with decreased unilateral function, including the forehead)
In patients with late disease, the typical physical finding is arthritis. Arthritis is located mostly in large joints, especially the knee. Warmth, swelling from effusion, and limited range of motion help distinguish arthritis from simple arthralgia.
