Lyme Disease

Pathophysiology

Early localized (Stage 1, 7-30 days): Spirochete replicates at the bite site, producing the pathognomonic circular erythema migrans (bull's-eye) rash in 70-80% of cases. Systemic symptoms include fever, fatigue, night sweats, and stiff neck
Early disseminated (Stage 2, weeks to months): Bacteria spread hematogenously, causing cardiac involvement (irregular heartbeat, AV block), neurological involvement (Bell palsy, meningitis, radiculopathy), and migratory joint pain
Late disease (Stage 3, months to years): Extreme intermittent inflammation of large joints (especially knees). Permanent joint damage from chronic synovitis if untreated. Chronic neurological deficits (neuroborreliosis)
Tick biology: Risk of infection is very low if the tick is removed within 24 hours. Nymph-stage ticks are the primary vectors and are extremely small (no larger than a period), making detection difficult
Coinfection risk: The same tick may carry Ehrlichia, Babesia, or Anaplasma, producing concurrent infections with overlapping symptoms
Geographic distribution: Most prevalent in northeastern, mid-Atlantic, and upper midwestern United States. Also present in southern Canada

Bull's-eye rash (erythema migrans): Expanding circular rash at the bite site, often with central clearing. Pathognomonic. Present in 70-80% of cases
High fever, fatigue, night sweats, headache, stiff neck
Swelling of large joints (especially knees). Facial drooping (Bell palsy)
Swollen lymph nodes. Heat and tenderness in affected joints
Irregular heartbeat (arrhythmia) or dizziness (cardiac involvement)
Numbness, tingling, poor coordination (neurological involvement)

Bull's-eye rash with systemic symptoms — immediate medical referral for antibiotic treatment. Delay increases risk of dissemination
Bell palsy (facial drooping) in a client from an endemic area — screen for Lyme as the cause
Heart block symptoms: Lightheadedness, syncope, or chest pain in a Lyme patient indicates cardiac involvement requiring urgent cardiology referral
"Worst headache ever" with stiff neck — may indicate Lyme meningitis. Requires emergency evaluation

Subacute and chronic phases: Massage helps maintain joint function, relieve pain, and reduce stress. Particularly valuable for managing the chronic fatigue that often persists after treatment
Severe joint inflammation during the arthritic phase is a local contraindication — do not apply direct pressure or mobilization to acutely inflamed joints
Cardiovascular involvement: Avoid rigorous circulatory massage if the cardiovascular system is compromised (arrhythmia, dizziness, AV block)
Neurological involvement: Work only when sensation is intact. Assess for Bell palsy (facial work modifications), peripheral neuropathy (sensation testing before deep work), and meningitis signs
Tick awareness: Therapists in high-risk geographic areas should recognize ticks on clients during treatment and counsel clients about prevention (tick checks, prompt removal within 24 hours, proper removal technique)
Post-treatment Lyme disease syndrome: Some patients experience persistent fatigue, pain, and cognitive difficulties after completing antibiotic treatment. Massage provides palliative support for these symptoms

Bull's-eye rash (erythema migrans) is pathognomonic for Lyme disease — any client presenting with it needs immediate medical referral
Know the three stages of progression and their distinguishing features
Coinfection risk with other tick-borne diseases (Ehrlichia, Babesia)
Early cases were originally misdiagnosed as juvenile rheumatoid arthritis (historical context)
Lyme-induced Bell palsy is a recognized neurological complication

The bull's-eye rash (erythema migrans) is pathognomonic for Lyme disease. Any client presenting with it needs immediate medical referral for antibiotic treatment.
Severe painful joint inflammation during the arthritic phase is a local contraindication. Avoid rigorous circulatory massage if the cardiovascular system is compromised.
Work only when sensation is intact and inflammation is not acute. Massage helps maintain joint function and relieve pain in subacute and chronic phases.
Risk of tick-borne infection is very low if the tick is removed within 24 hours. Therapists in endemic areas should counsel clients on prevention.
Coinfection with Ehrlichia, Babesia, or Anaplasma from the same tick produces overlapping symptoms that complicate diagnosis.
