PS: About your Mum... Lisa seems to agree (and she should know!) and it did sound like it could possibly be a TIA to me..My FIL had a few of these 1-2 weeks before his last major stroke. I wouldnt leave it.
I understand your Mum is stubborn (FIL was and wouldnt go to the docs).. so how about you call her doctor/your doctor on her behalf and tell them what happened and get them to do a house visit, or call her, if she wont go herself? Sorry to worry you, it might be nothing, but it sounds like what happeend to FIL.
