Boyfriends terrible allergies..

My boyfriend has allergies to anything outdoors, including humidity. Everytime he cuts the grass he's on the verge of passing out. My worry/question is this:

This morning he cut wet grass and come over fine. Later today he developed a horrible fever (102.2), chills, a severe headache and some body aches. He claims it's his allergies, but I think he might be coming down with something.

could anyone give me insight on outdoor allergies? Has anyone ever experienced what my boyfriend has?

Thanks in advance. ^^

I'm so sorry that your boyfriend is going thru this. Has he ever had allergy testing done? I have never heard of someone with that high of a fever with allergies. Hay fever is a contradictory of terms because it doesn't really produce a fever. It was believed to do so in the past because your face feels flushed (hot) with some allergies and people believed that if the face was hot, you automatically had a fever. To me personally it sounds like he is coming down with something too, maybe the flu?

He went to the doctor today, was told that he either had kidney infection or meningitis. the doctor was leaning more towards the kidney infection, because of his symptoms (sudden onset of chills, fever, nausea, lower back pain, etc) but the only reason the doctor considered meningitis is because of the horrible headache he had. The one he still has.

I knew it wasn't due to allergies. :(
Thanks for your help!
