Hi Mandy,
It may be that your immune system needs strengthening, especially now in the fall. There are many ways to do so. Honey and ginger in the morning, garlic, echinacea, ginseng, anything that will give you energy. It could be your hormones fluctuating but it could be also general tiredness that is associated with this time of year. Is your conjunctivitis confirmed? If not, it can also be an alergic reaction of the eyes, including the swelling. It can be also dry eyes which can get very red and inflamed and itchy , also swolen. My dry eye condition was mistakenly diagnozed at first as conjuctivitis, as symptoms are so similar. I was treated with corticosteroid drops which worsened the situation. It took almost 3 months to diagnoze properly and get good treatment.
