i've noticed my hands are puffy and ive had very painful diarrhoea last week, which through the course of one evening, I had two bouts, which start with sharp pains in my rectum, I then get abdominal cramps and the cramps get more and more aggressive until I get the uncontrollable urge to go to the loo.. While passing I get extremely painful cramps so much so it makes me feel light headed and dizziness. I have been feeling tired and keep getting headaches.. this im feeling extretremly tired and lights are hurting my eyes and i vomited when i got home from work but in the day i didnt feel sick.. the sickness feeling has been coming and going, a also have cold symptoms. Can you help?
