Why did this happen?

Patient: When i was younger i drank a breakfast carnation, and that night when i woke up my arm was numb and i couldnt move it untill i rubed it and got the feeling back, this became worse and started happening with all my limbs for a whole week. For the whole week I had to keep moving to keep from going numb. i never drank it agian. Why did this happen?
