My mom started out on March 1st with a headache and low fever. She has progressed to a sever headache and low to high fever, occasional sweating, and vomiting. She has swelling when her fever goes up. She had pain in her right abdominal area which spread to the rest of her body. She has swelling and pain in her joints.

It appears your mother has a serious medical condition which warrants immediate evaluation by a physician. Her symptoms are concerning for meningitis but are also consistent with the flu.

Sustained fever with abdominal pain, severe headaches, vomiting, and a history of gallstones (suggested by incomplete gall bladder emptying) is especially concerning for cholangitis. Cholangitis is a bacterial infection of common bile duct that drains the bile from the liver into the gall bladder and small intestines. It occurs most commonly from a gallstone obstructing the outflow of bile. Cholangitis is a life threatening condition and warrants immediate medical attention, antibiotics, and removal of the stone.
