Tony Stark request

[Glowie]

I'd love it if someone feels up to penning a Tony Stark fic, in particular where he suffers from unexpected allergies (illness is fine though, if it's easier). Extra special bonus points for Tony and Steve friendship, or at least Steve being in the sympathetic/supportive role. No slash though please. And preferably MCU, as that's the universe I'm more familiar with. But once again, I'm not too fussed! I just desperately crave some sneezy Tony and nice Steve. :)
