I have a couple of thoughts:
Anemia: You might have the specific test to verify the level of your anemia, and if you would benefit from an iron infusion, and or a series of ARANESP shots.
Sinus: It seems that you need to solve this issue with advice from an ENT. Using a saline solution in some form to clear your sinuses on a regular basis would likely help; there are multiple delivery vehicles such as the netti-pot, or bottle; I prefer the aerosol spray, but it runs a bit high in cost.
Immunologist: You might want to be checked for allergies.
Sore throat: The ENT will check for GERD.

Good luck
