I was diagnosed with a TIA 4 days ago. I've had a mild-moderate headache since. Is this common?

I am a 62 year old female who was diagnosed Tues with TIA. Released from Hospital after 24 hour monitoring. Have had a mild to moderate headache since along with a couple of episodes of nausea. The headache seems to move around from base of skull, neck, top & sides of skull. Neither my primary or neurologist was able to see me Friday, so I am trying to figure out what to do over the internet. I've also feel too tired to resume my daily 3 mile walk...or even a shorter walk. I've had some trouble sleeping. Is this common. If so, when can I hope to feel normal again.
