Test required: It is important to try to se a doctor (any doctor) a soon as possible and make some lab test to be sure that everything is fine (blood tests). With te information that you provide it is not enough to make a diagnosis, but it is enough to suspect that a check up must be done and some important health issues must be ruled out. Do you have fever and chills at nights?
