Neurological conditions can be difficult to diagnose. Our lovely daughter had a similar episode one night, when she was 7, nothing more since then. The Drs said she had a benign form of epilepsy, never even had to take meds for it. Prayers sent 🙏🙏🙏🙏
I had something sort of like that. Picked it up while getting a transfusion. I named it leg plague, usually on my legs sometimes in arms and legs. Doctors told me it was all in my head and I was a nervous Nellie. Suffered for over 50 years every night. Then my brother 4 years younger came down with something like it. His Dr. in Calif. said he had hemochromatosis and put him on Mirapex.
That is a Parkinson med. I have to take it on schedule, but I am free of it. If you take too much, you will get the hiccups.
