Hi @IanM
First is I actually think your symptoms are typical not atypical. See
Did ANYONE have classic FAST symptoms
Public and even the medical profession are misinformed by FAST to think it is typical and it’s not (given the empirical evidence above) - would be really good if the stroke association carried that message but they promote the old one 
My MRIs showed that I had had multiple undiagnosed strokes (silent) before the one that landed me in hospital and i shared experiences with you such as partial vision losses. I also sometimes had migraine aura but unlike you I don’t think the muscle weakness affected me - there is a lot of migraine aura threads about maybe these are “a” typical early warning symptoms. Is there a day after feeling other people might call severe fatigue rather than after effects of a TIA?
Have you been checked for AF arterial fibrillation and PFO and diabetes and sticky blood? Is your BP under control are your iron and other blood chemistry parameters such as cholesterol under control?
In the first year post hospital I went to A&e when I felt like that. Now I feel 13 hours in a corridor to be told “don’t know what it was, don’t know why it was, could have been the TIA, take aspirin for 28 days come back if it happens again” has more steps in it than I need so I don’t bother going to A&e
If you can rule out that you’re suffering fatigue and you’ve had all of the tests that repeatedly asking what tests are relevant and reading here what tests other people get, and you’re taking your meds and they are keeping your parameters as close to recommended as can be then in my unmedical opinion the best thing is to make the most of life and maybe employ some anxiety management techniques for what is always a worrying combination of feelings
Maybe others will come along with more insights
