I'm 19 and male. Back in June I was experiencing headaches and dizziness, that has long passed but now I have been numbness in my left cheek that has lasted for the last three weeks.
I have had a CT Brain Scan and nothing came of that (two months ago). Numerous blood and urine tests and generally been checked out about four or five times. I'm going to see my GP tomorrow and I can just see her thinking I'm insane.

If this was a sign of a stroke surely it would have happened by now and the CT scan would have shown something would have?

My chiropractor told me it's likely to be cluster headaches and I've also been told it's likely to be my nerves.
Do I have anything to worry about? Because I'm positive my GP won't do anymore and would feel there's nothing wrong with me.
What more test can be done to ensure I'm not going to have a stroke?
