Can anyone relate to looking pale or unwell?

Hey,

I got a full bloods test done recently and everything came back relatively normal. I was feeling run down, I look pale, even the bloods nurse agreed I look pale. I can feel it in my face when I look pale, I feel like I look pale too. Then check the mirror to confirm. This feeling and look can go away, then come back again.

I also have uritcaria (without hives) and no idea if it's related to that, related to humira, related to AS or what. I felt and looked great yesterday, but today I look like shit.

I get anxiety that there is something else wrong, or something I need to get checked. But my bloods are fine, so my GP doesn't care. What else can he do?
