Infectious Diseases: Strongly suggest you find an infectious diseases expert in your area and make an appointment to see them. This is the classic fever of undetermined origin and a good id person will be able to evaluate and hopeful solve this problem.

See your PMD: My suggestion is for you to see your pmd to help find the cause of your problems- instead of going to er frequently. Your symptoms can be caused by different things like infection, connective tissue disorder/autoimmune disorder, as well as malignancy/cancer. Go to see your pmd. She/he would be able to take a careful history, examine you well and refer you to the right doctor and work-up/procedure.
