What Do Swelling And Tenderness On The Face Indicate?

Hi. For several months, I have been bone chilling cold, my skin had been tender to touch in my face on one side, gums swollen but no visible canker sore, flu like symptoms but no flu. I have Aspergillus disease and recently had an allergic reaction to something and my ethmoid sinuses and my eye was swollen as if I had an infection. Only taking allergy medication would help. Additionally, I have had this sharp pain in my lower left abdomen and been somewhat sleep deprived and taking a excessuve amou of caffeine sometimes. Any suggestion as to what may be causing these symptoms
