Over the last week or so I've felt awful. It started with severe stomach bloating which died off but I still get occasional cramps in my stomach/rectal area, with some itching down there aswell. But I've also felt very tired all the time, arms/legs feel fatigued and I just want to get in to bed all the time. Does this sound like IBS or something more serious? I've scheduled an appointment but the soonest I could get was next Friday.
