Cold spots inside head and under skin help!

[Amyk34]

Ok so I have had migraine issues for years first it was only monthly with my cycle now I get them in between that too but they are different like I get a "cold brain" feeling like cold spots in different spots on myface and neck too does anyone else get this? I get this feeling even when i don't have a headache or migraine....I don't know if it's cause I have migraines or if it's a symptom I got after idk it's just really weird and scary keep thinking I have MS. I got a normal cat scan result a month ago. And normal blood work anyone have these cold spots or sometimes hot spots on the face and head?
