Lily,
I have also had severe facial swelling for the past year and had a lot of gastrointestinal issues. I do have high markers for RA and my c reactive protein levels are off the chart but I do not have RA symptoms. Do you have histamine issues from food, skin care products, etc? I think I have leaky gut and dr thinks this is what has recked havoc on my body. I am not taking any meds but am doing natural route to heal gut. My facial swelling is now reduced by about 40%. I am on oil of oregano and grapefruit seed oil. I also have possible candidiasis in gut and sinus areas. Probiotics are also helping facial swelling. Maybe you should check into this more.
