I had a hida scan on tuesday then ran a 100.0 fever on wednesday only for about a few hours that went away and i'm better now! should i do something or since i'm better just not worry about it?

Observation: If you feel fine and do not have any other signs or symptoms, i would recommend observation. If signs or symptoms recur, then you need to see your doctor.

Probably unrelated: If hida scan was noraml the fever may be unrelated. An elevated temperature suggestive of infection is seen in 1/3 of patients with cholecystitis (inflammation of gallbladder and > 90% with cholangitis, inflammation in bile ducts. These patients usually have abnormal results to the gall bladder study.
