Hi, I Have Just Been Released From The Hospital For

Hi, I have just been released from the hospital for the second time this month with weird neurological symptoms. 1st, stroke like symptoms that ending up showing only chronic migraines. I received home physical therapy. 2nd, last week, I suddenly collapsed and now can not walk without a walker and assistance. The hospital did MRIs' of the brain and spine and numerous blood work and could find nothing. I have a history of sarcoidosis, but I am just fustrated. They checked my blood sugar, cortisol, etc. I now depend on a bedside commode, walker, etc. I also have tremors. I can move my legs all I want when I am lying down but when I stand up, they are like
wet noodles. Please any ideas?
