red face only after sitting

[mattcg]

Hi everyone, I'm on my last straw here. When ever I sit down within 10-15 min my face turns extremely red and burns. I can feel it first start to burn and pin pricks under my eyes top of cheeks. Soon it will be over my nose bridge then move to my whole cheeks then up side of face and sometimes to four head. What's weird is that it stops at my whiskers line.  This has been going on for a few years now but with only seeing a dermatologist for the last 6 month's but all cream's and steroids are making it worse. I have also developed stomach issues around same time as above red face issues. I have found if I stay away from gluten my stomach is much better. Another symptom is being very irritated all the time but maybe that's the fact that I can no longer sit down for dinner or with friends at cook outs or just hanging out with out face getting red. Sun, hot, cold, exercise etc.... all  normal rocacia triggers and symptoms dont bother me. Please help some ideas check out pic I uploaded, thanks
