<s>[INST] five year old daughter going on third day of high fever. she complains of neck pain and right lower back pain. she is not eating but taking little fluids also she is not out putting any fluids. been to doc twice this weed but say just viral infection but to me something just does not seem right. [/INST] However and malaise (body ache) are initial presentation of viral fever. You have to see if she is fine in between fever spikes. If she is sick even when fever subsides it is a reason to worry. See if on bending neck forward is possible, or it causes pain. If these signs are positive immediately seek medical attention. If she is happy and playful when fever subsides you can wait as doctor said it is most likely viral fever. </s>
