High stress level

My husband has a very high stress and anxiety level right know. My husband was told he has BFS and this did not accure until he hurt his back about 5 months ago. The doctors said that were he is not able to work that the stress anxiety has kicked in. He went for a emg and it states he has BFS but, he does not believe this and is having alot of issues. I am not sure how to help him through this at times. The muscle twitching are wacking him up through the night and never stop during the day he can barley sleep. They are all over his body. The doctor states and has told my husband he does not have this but, he still feels he has ALS. My husband is on buspar,baclophan for this and he still feels like there is a motor running in his body but, the doctors states that is nevers. Please help with some advise.

Thanks,
