My now 8 year old son was diagnosed with Post Streptoccal Glomerulonephritis over a year ago. His hematuria went away after about 3 months (when his tonsils were finally taken out). It's now 1 year later and he starting experiencing urinary frequency and then gross hematuria. The gross hematuria has been going on now consistently for a week. No pritenuria & BP is normal. Peditarician says not to worry and doesn't want to refer him to a Nephrologist. Should I push the issue?
