First of all, are you on any meds? If not it seems like you might be eating or drinking something you are sensitive to. When I had systemic Candida I had the most severe food sensitivies, chemical/environmental sensitivies that you could imagine. If I sat in a damp cold place, my ears would ring so loud, my feet and cheeks would get numb and my eyes would get puffy and sore.
This would be the first place to look.
