I was exposed to Toxic Black Mold for 5 1/2 months.  Approx 1 month or so after moving into the home I developed bilateral kidney pain.  It has persisted off/on since March of this year.  Dr's I have seen have not been able to provide a diag.  I had a CT scan of the kidneys that was neg as well as neg blood work.  Now I am at a loss.  I do have decreased urine output, but to me it seems odd the symptoms developed after moving into this home.  (it was a lease and I no longer live there as I moved out after the mold was discovered).  Some days I have no pain and feel great.  Others, like the day I went to the ER, I was nearly doubled over in pain.  The Er phys dimissed the pain as being kidney stones and when the test was neg all he did was prescribe pain meds!
