What kind of a doctor should I see for skin flushing?

For over a year Ive been Ive been having some sort of skin flushing. It tends to happen if I lean forward or backwards. Things like having makeup on, wearing jeans or a jacket, weather make it worse.

Sometimes it gets so bad that it REALLY hurts. My cheeks mainly get affect, my chest, top of my arms, thighs and toes sometimes. It's typically small red patches or giant red patches.

I've brought this up with my primary care doc and he refuses to help me with it because he says 'I don't know what it is,it's probably just stress, have you tried meditation ?'. My therapist and family members strongly believe that it's not stress and I agree.

I'm wanting to just go see a specialist if I can I just don't know if I should see a dermatologist or another type of doctor?
