For the most part, your blood tests look reassuring.  Going to the emergency room will get you seen by the emergency room doctor.  They may find something in your mouth or ear that may account for the lump you are feeling.  The emergency room doctor would still need to refer you to an ENT, but you might be able to get in before a month.  The other option is to contact your primary care doctor and see if they can talk to the ENT office about getting you in earlier. This may require a visit to your primary care doctor.

Standard practice for investigating the cause of blood in the urine includes blood, urine, and radiology tests.  A urologist will also need to look into your bladder.  That last test is probably the most difficult test to have done.  A CT scan would help to finish your investigation as to why you had blood in your urine.  This is a good way to may sure you do not have tumors in your urinary system.  You may need to have an additional blood test done prior to the CT scan to make sure your kidneys can handle the injected dye, if that will be needed during the CT scan.  I think having the CT scan would be a wise decision.

It sounds like you may have juvenile idiopathic arthritis.  However, the best course of action is to continue to work with your rheumatologist about your condition.  Autoimmune illnesses can be difficult to diagnose and manage.  Your rheumatologist has probably run all the appropriate tests for you and it can be very frustrating when a definite diagnosis cannot be made.  But, that does not mean that treatments are not available to try.  If your rheumatologist is not able to provide any additional assistance, you may need to be referred to a university medical center and see a rheumatologist there.
