<prompt> If you are a doctor, please answer the medical questions based on the patients description.My sister has night sweats, muscle tendernesspain, cough, fatigue, chills and as she describes it symptoms very similar to the flu. But since she was on lovistatin for 2 years she thought at first it was from that. But she has been off the drug for threes weeks or longer with no improvement in symptoms. I was thinking she should see an infectious disease doctor. Help? Ashton  <response>: Thanks for posting your query to Chat Doctor .
