Fearing food poisoning

[searcherrr]

30 year old female/sister & 33 year old male/brother living in same home. Ate same meal 4 days ago when this started, but 2 other people at the same meal and are not having problems. The meal was bbq roast beef on fully dressed 12" French bread, though since halloween we have also had many different foods especially on halloween night.

Both of us for 4 days now - Burping spurts, Frequent Gas, Floating Stool, Feeling like FULL or SWOLLEN Abdomen from top to bottom, no vomiting (brother) - yet a feeling of wanting to - so we stop eating as much, loss of appetite, watery broken up stool, stool made in small bits accompanied by much more gas than stool (usually only fills the drain hole at the bottom of the toilet; usually is a lot more), cramping.

SISTER: Vomiting - My sister vomited once and it was today (4th day). I have not vomited though.

BROTHER: Slightly raised red hives (round) with white center and red surrounding area. Have had 1 under left armpit, some on face and sometimes feels like it trying to break out on neck. I feel pressure in my head constantly until I go to the toilet and let some stuff out. I cannot move at all without feeling like I will have to immediately go take a dump. Any activity "stirs" it up and what I cannot understand is I'm not eating my usual amount anymore and yet I still feel like I have to go to the bathroom.

Treatment: We have been taking stool softeners, anti-acids, laxatives, hot chicken broth, lots of water and fluids. My sister hasn't been taking any laxatives or softeners. She claims to want to pass it naturally cause she says she's had food poisoning before.

Questions: What tha hell? I keep feeling like this is going to be over after sleep and the 1st time I go to the toilet it is like it starts a chain reaction to put me through it again for the rest of the day. I only get peace/relief when I sleep. It has become extremely fatiguing to both of us. Should we go to a doctor? Anyone have any idea what this could be?
