We think my sister -in-law has something called PODS....please explain and what should she be doing she is not getting very good medical attention and she has fallen and had 21 concusions we are freaked out but don't know what to do. PLEASE HELP! Her symptoms are... she can't stand up because when she does her blood pressure shoots up and she faints, she has short term memory loss, and now is having burred vision and headaches ( I realize 21 concusions would also cause some of these symptoms but we cannot get through to anyone) Thanks you. Kim
