Hi, I had a stroke in March. The only symptom was my fingers started to move involuntarily and then my hand went limp. I didn't go to the GP until the following day. When they did the CT scan, nothing, but the next day, they did an MRI and there it was. A definite stroke. They are all different with different ranges of symptoms, the scan will give you a definitive diagnosis and then you know what you are dealing with.
