Enlarged heart and heart-rhythm disturbances. Many patients report a tick bite at the site of the lesion 3 days to 4 weeks prior to the rash. Have dogs and cats wear tick-repellent collars. The skin rash is curable in some patients in 10 days with treatment, and this may prevent development of other symptoms. If not, symptoms in the joints, central nervous system and cardiovascular system usually subside slowly over 2 to 3 years.
Symptoms often recur after several years without another tick bite.
Permanent joint deformity. Early treatment is important to prevent progression and irreversible neurological damage. Use crutches to keep weight off affected joints, if necessary. Heat relieves joint pain. Take hot baths or use heating pads.
