My husband has an infected intestine from eating a peanut?

He just went to the clinic and came back with some insane antibiotic for something he doesnt have symptoms of.

He said it was dybarticulitis? Apparently he had a slight cold and ate a peanut which carried the virus to his gut where in the matter of 24 hours created a severe infection.

They took blood but didnt wait for the results to see if that indeed is the issue. I looked it up online and all that i can find it divarticulits (sp?) which you actually have to be TEST for extensively to know if you have it.

He has just regular flu symptoms, a fever, the runs, nausia but not throwing up, achey and tired. He did have a cold before, and then this set in yesterday.

He's not aching on one side of his body, he's not sore to the touch in his belly, he eats well and has an excellent exercise routine, and he's not over 50... nothing matches up with the symptoms of what theyre treating him for...

He always acts soooo sick and exaggerates his symptoms, but when asked, he has NONE for this...
