I am veteran with severe ptsd. i've read that "stellate ganglion block" has had high success rates treating other vets. who should i see to try this?

See your doctor : Thank you for your service! Also, thank you for this question. You may want to start with your primary physician for a referral to an anesthesiologist skilled at this procedure. From what I have read, some people get immediate results and others get no response. If you are treated in the VA system, a large tertiary care center will be your best bet.

Still experimental: This is still undergoing study. The early promising results were from uncontrolled trials (case reports). More recent studies have been unable to replicate the results. It isn't clear YET if positive effects reported in case studies were simply placebo effects, or if there are some people, yet unidentified, who respond well to the treatment. As mentioned, discuss your interest with your physician
