During A Nissan Fundoplication Surgery Whoever Severed My Vagus Nerve.

During a Nissan Fundoplication surgery whoever severed my vagus nerve. I have a lot of pain from my neck down to waist. I also have trouble eating as my stomach gets bloated easily. I'm very careful what I eat as I had IBS problems. I don't know if coughing, a deep cough, and sometimes I cannot keep my food down. Do you know if there is a qualified specialist that could help me. I also have Myofacial muscles and ended my last workplace disabled? I see you recommend Mayo Clinic do you have to a a referral to see one of their doctors. One of my doctors told me to make arrangements with Mayo, but I do not have a referral.
