Trying to Find Out What Is Wrong With Me

I am a 47 year old male and have been type 1 diabetic for the past 12 years. I have had some rheumatic type problems lately with swelling of joints and pain especially in the mornings. Was diagnosed with plantia fasciitis or something like that and had cortizone injections in my feet (oww) and it seemed to ease the pain in the soles of my feet. I get pain in my wrists and ankles and knees. If I knock any of my bones it takes ages to heal up. My big toe is painful but not on the joint but on the end of the toe. I get tired and have difficulty sleeping sometimes with the pain, I take brufin 600mg once or twice daily and this helps. I went to the hospital today for my blood test results and the doc mentioned all results were ok except something to do with lupus reading which should be 8 or below, mine was in excess of 200. Dont know if this is the onset of lupus and sure hope it isnt having read some of the things some of you poor people are suffering with, but I would like to know if my symptoms are indicative of lupus. I have stopped working in the mornings and dont go in til around lunchtime when the pain seems to have reduced significantly. I have an appointment with the rheumatologist next week. Any questions I should ask him?
Forgot to mention getting an aching pain in my back where I imagine my kidneys are.

Kindest regards
