For 3 weeks, have felt really odd, very out of sorts. Friends and colleagues have noticed. Feel like I.might keel over every so.often, always to the, same side. Head is fuzzy, keep forgetting names, words. Feel "thick" and have to have things repeated/explained. This isn't like me at all, normally bright, articulate, sharp.have seen gp, she referred me for MRI as my ds had ruptured aneurysm 3 years ago. (survived). A, week later, I'm chasing up the referral, which hadn't arrived at radiology, and was told it's at least 4 week wait. This, seems awful!! I'm sure this is just some viral thing but am.worried and, want someone to hold my hand.
