If it does turn into an infection, I would recommend olive leaf and grapefruit seed extract and keep up the kelp but you might want to cut back on the burners since they may be creating too much heat during a healing crisis such as an infection.
If it is your kidney flushing some grit, the cranberry is good. Make sure it does not have high fructose syrup in it. Eating some lightly steamed asparagus is great. And if you have a juicer, Watermelon is the best tasting kidney flush. Juice the seeds too.
Good Luck. Im glad you are feeling better already. With luck, it was just some irritant which your body did not like...there is Capscium which is cayenne in some of the supps you are taking and black pepper in another. So the dose of cayenne you are getting could be substantial. This could possibly be the culprit.
