I think you need to call your doctor and ask him what the white spots could be...
Diagnosed w/colonic inertia, obstructive defecation syndrome, anismus, rectocele, and intussusecption
2005-hysterectomy w/pelvic prolapse repairs
2010-subtotal colectomy, rectopexy, and temporary diverting loop ileostomy. Parastomal hernia discovered in November, so more surgery, probably end ileostomy with relocation of stoma.
