Off to the Allergist

I took Lucy back to the park this morning with our friends and she had another pain attack right there in the park. It was terrible. She was all curled up in my arms just moaning. We beelined back to the house because I couldn't get her to stop and she really was just miserable. I ended up having to carry her and push the stroller with one hand.
I called our allergist and he wants to see her so we can discuss things and what(if anything) we are going to do about this. Typically this thing would pass, but I cant figure out exactly what is setting her off- so she potentially is just being exposed to something over and over and I don't know it. Hope and pray that it is NOT her formula again. We exhausted all our options for formulas last year when this happened and the one she is on now is the ONLY one she was able to tolerate.
We should be getting an appointment with Dr. S. tomorrow!
