Rib cage pain with face hands feet and leg tingling

I've had rib cage pain (from front to back) for three years. My hands and feet have been tingling for a long time too. Last week I went to walk up the stairs and my legs wouldn't move for a few seconds. I feel electrical shocks all down them and they go numb and tingle. I have also been "throwing" items for the last two months. I just pick something up and my arms jerk and I drop the item. Now cheeks, mouth and nose are tingling. Had MRI of brain and EEG and both came back OK. Neurologist looked at me and said "you look good" but did send me for more test. From all of my research of symptoms I am having MS pops up for all of them but I am guess since the MRI of brain didn't show anything that I can rule that out but not sure??? Symptoms are getting progressively worse quickly. Any suggestions would be greatly appreciated, I have a 3 1/2 year old and 9 month old boys that I need to be healthy for. Thank you!
