Question: I have been sick for over three weeks I ve had Dear Ask The Doctor: I have been sick for over three weeks. I ve had drenching night sweats (having to change my sheets and nightgown in the morning, it s terrible), sore throat, recently leg weakness (having to sit down quickly in fear of collapsing with my daughter in my arms), arthritis like pain in both my hands now, natural light sensitivity, a productive cough (dark sputum), and temperate issues (body is either on fire or I m freezing). I am a 21 year old female. And am sick of feeling ill and exhausted all the time. And my doctor says I just have a cold. Please help.
