I have a bad headache with nausea and a tingling right hand - is that a migraine?

Could be: Have you had migraines before with similar symptoms? If so, then this can be a migraine variant. If you have never had a migraine before then at age 35 you need to be evaluated by ER or urgent care. It would be unusual (but not impossible) for you to start having migraine headaches at the age of 35.

Migraine or other: It's very common for Migraine headaches to be accompanied by nausea, and not unusual for other nerve-type symptoms (like a tingling hand) to occur as well. However, symptoms like this can be caused by other things as well. If this happened suddenly today, I recommend you seek care right away (ER, for example). If these symptoms come and go, discuss with your doc and consider a Neurologist visit
