hi, welcome to HCM. Blood in stools can be due to various causes like piles, infection, a local tear in the rectum
, increase in blood pressure, or even colonic cancer. Do get a local exam of the rectum and a stool exam done first and if local causes are excluded, then you can undergo a colonoscopy
to rule out cancer of colon. Mostly the case may be one of piles, so do not worry unduly, but get yourself checked. The throat irritation
may be a mild flu
and needs just gargling and steam inhalation unless it becomes severe. Regards.
