You must must must try the water cure and its various aspects. Sinus/allergies and aching joints are classic signs of dehydration.
I used the water cure successfully to rid myself of most allergy symptoms I even started having asthma symptoms which went away in two days of drinking sufficient water. You need 1/2 your weight in ounces of water and a little unrefined sea salt per day the pink Himalayan is great. You also need iodine, I used kelp and then later Lugol's solution. Magnesium, I use magnesium oil. The rest of what you need you will most likely get from your food. The water has made a huge difference for others who I have recommended it to.
One lady is off daily doses of Benadryl. Now she only takes it as needed. I am off of Zyrtec. I have stopped needing antibiotics 4 to 6 times a year! This has been a huge life change for me! I am about to turn 40 and I am so proud of taking control of my own health!
