Always, Always get a second opinion and request referrals. Research some of the well known Medical Centers, Mayo., John Hopkins, Cleveland Clinic, Temple and Duke. I live inn a Medical-Care Challenged State and had to leave the State..... Duke is a great place to start. You will find a wealth of knowledge and people more than willing to help you, plus you can even self-refer. The VA physician should be willing to assist you with this......the least he can do is give you a referral. If he won't go the the Quality Assurance/ Risk management department and lodge a complaint.
