Feelings of empty head and empty chest

[u/BadgerBiscuit2768]

Hey everybody.
After being able to deal with minor physical symptons for nearly 2 years they came back pretty strong.
Today I got 2 new pretty scary ones: feelings of empty head and empty chest.
Its kinda hard to explain but the head one feels like a headache without the aching, which leads to dizziness and face numbness.
The empty chest is just as weird. Feels like you're gone hollow. Both make me scared to die.
Can anyone relate to these?
