Hi there, I have experienced a very sensitive stomach for a long time, feeling nausea and often having pain, however that has now subsided but I've just had two full days of diarrhea symptoms and for a while now, an itchy behind. I have tried worm treatments, I've tried probiotics, recently tried a new vitamin however needed to stop due to constipation. I'm at my wits end because I'm never feeling right in my stomach and lower!
