See doctor: These symptoms and lab findings can be manifestations of various illnesses. Your health issue needs a systematic approach and often further testing to point out the underlying disease... You need to see a physician if haven't yet.

Many symptoms: These various and multiple symptoms involve several parts of the body and present a complicated diagnostic problem. I think that the best course is to have a thorough history and physical examination by an internist and collaboration with specialists in rheumatology, neurology and hematology. Appropriate tests will be done in order to make a diagnosis.
