Hi I ve suffered for years with diarrhea, blood and mucus in stools, severe left abdominal pain, vomiting, fatigue, dizziness, and pick up every infection/virus going! I m currently under investigation for Crohn s disease, Ulcerative Colitis and bowel cancer (still undiagnosed after 15years) lately my anus has been very painful, itchy, burning, and now has lots of tiny yellow dots accompanied by red dots like pin pricks. What could it be? I m very worried and in alot of discomfort
