Anyone else unable to use powder formula?

For the past 4 months, I have been dairy, soy, egg, nut, wheat, and oat free.  All of those things give my DD diahrrea/hives when I consume them and then nurse.  Her stools are STILL abnormal (ie mucous and green) even though I'm on a very limited diet.  For this reason, I want to switch to formula before she starts solids so I can monitor her reactions better. 

We tried both the alimentum powder and the alimentum RTF formula.  The powder gave her hives while I was feeding her (I'm assuming it's from the corn starch).  We did a trial for the RTF formula for 24 hours and she seemed to tolderate it fine.  I'm hoping she will be ok if we completely switch.

Anyway, is anyone else's baby this sensitive?  I feel so alone.  Not only is she MSPI, but she has all these other sensitivities/allergies.  Has anyone else not had luck with any powder formula?
