are you present online?
The symptoms that you are describing indicate -
- a severe allergic reaction - you might be allergic to sun, dust, any new face cream/lotion etc
- an autoimmune disease like SLE (systemic lupus erythematosus) or lupus. Though you do not have any other symptoms, the face rash might be due to lupus. Considering that you have a high CRP, an autoimmune or rheumatological disease is a possibility.
So, your doctor has taken the right decision in refering you to a Rheumatologist.
