Can I still have surgery if I was given a 125mg dose of solu medrol?

I am scheduled for a breast augmentation tomorrow. This morning I woke up to areas of itchy rashes on my stomach. Went to an urgent care facility who gave me a Benadryl injection and the solumedrol. I was told that I was most likely reacting to a new medication (celexa which I have quit taking) and since the visit the rash and itchiness is completely gone. My surgeon has not returned my call and I am scheduled tomorrow morning for my procedure. Any help would greatly be appreciated. Thanks!
