So this all started in 2015. I was laying on the couch watching a tv program when out of the blue i had strange heavy sensation in my legs then it ran up my left arm, chest then face. After WE and hospital stay they couldn't find anything. 3 years later still having problems with new symptoms. Now burning, numbness and pain in feet were I can't walk, trouble sleeping even with cpap, shock like sensation all over my body along with a numb feeling and itchy in random areas. I done all testing except a 2nd nerve conductive test and all show nothing. This has all brought on anxiety and depression Which Is making It worse. I feel like I have been swept under the rug, helpless and hopeless now. I'm using a walker on a daily basis and need answer.... Please help me.
