i have acute numbness, tingling and severe pain from shoulders to fingers with now very limited use. shortly after onset my knees and feet and toes were also affected. my left knee frequently gives out from pain and weakness. it s becoming increasingly difficult to care for my 3yr old autistic twins. i have seen ortho, neuro. rheumatoligist and spine specialist. awaiting results for lyme disease and if negative will have brain mri but neuro didn t think of ms. i desperately need a diagnosis. any thoughts. thank you
