Hi BeccaJane,
I am so sorry that you're going through all of this, and want to thank you for reaching out here!
You mentioned your gp and having had a ct scan back in June, so you don't need an mri. Is she following up with these symptoms in any way? Maybe recommending you to a neurologist??
While we can't give you any medical advice for your own safety, I would sure pursue this until you have all of your questions answered to YOUR satisfaction! Don't be shy about pushing this forward...you need answers.
Please keep us posted on this and let us know how your doing! We'll be thinking of you...Janus
