HELP!!! I don’t know what is happening to me…

My muscles are weakening and twitching all the time. I have been dropping things constantly. My muscles feel like they are in a sleep state. That feeling you get when your leg falls asleep after being in a certain position for a long time. That annoying ache that you can’t wait to subside so you can move on. Well that’s not happening. From my neck down, all the muscles are in that sleep state. I feel like crying all the time. When I walk my legs buckle from up under me causing me to fall all the time. I use a walker as it is because of two recent Lacunar strokes. I fear this Sarcoidosis has finally won after 17 1/2 years. HELP!!! Anyone else suffer with this? I made an appointment with my neurologist in two weeks. It’s just lasting to that appointment. HELP!!!
