Tick bite. Ticks can carry bacteria that cause diseases like lyme disease, ehrlichiosis, rocky mountain spotted fever. Some forms of ehrlichiosis & rmsf may be associated with liver enlargement. If you suspect this condition, see your fp for exam and blood tests to rule out these diseases, which, left untreated early, can lead to serious complications.
Ticks and Disease. Some cases of hepatitis (liver inflammation) have developed in conjunction with lyme disease. However it has been difficult to determine if the hepatitis was actually caused by the lyme disease or by some other factor. Other possible causes could be a virus, gallstones or another tick-borne illness such as ehrlichiosis.
