Hi, im 25 years old female, for about 6 months i have experienced problems using the bathroom, I started to have blood, bright red bloos in my stool and a lot of pain while using bathroom and flatulance...I have had a scope and doctor said everything is normal in my intestine I onlt have a anal fissure which im treatment with a cream and im also having fybers. But since then I have had some episodes of diaherrea sometimes, and its still painful to go bathroom and i still have the flatulence feeling. Last week i start to have puffy eyes, which is worse in the morning, big bags under yes like when you spend the night crying, i have never had it before and i am also very thirsty....any clue of what could it be???
