What Treatment Is Suggested For Protein In Urine ?

I urinate visible blood , sometimes for a short time and sometimes for a couple of days. I also feel and can see a blob come when I urinate, on occasion, when the blood is present. This has been going on for about 5 years. I have been to doctors and have been diagnosed with protein in my urine and was diagnosed as diabetic. However, I was re-diagnosed and found not to be diabetic. I was also diagnosed with the kidney filters being damaged but after the re-diagnosis of diabetes nothing was said about it again. I have gone to the doctor many times because of the visible blood and occasional pain and was told everything from my back is out to hormonal changes. Naturally, I gave up. The last few days I have had trouble urinating then this morning a big blob with much blood came out and I can urinate normally again. What is your diagnosis?
