My 10 yr old son was diagnosed with PANS by an integrative medicine doctor by the name of Mae Kinaly in Irivine, CA. We live in Manhattan Beach in LA county. She did a ton of blood work, in depth history and immediately started him on azithromycin and supplements. She is a little kooky but I feel is a very in depth doctor with my son's best interests at heart. She does offer IVIG. We also went to Dr. Miroslav Kovacevic in Chiago for a second opinion and ultimately IVIG. Hope that helps.
