I just had a similar experience to yours. Except I was cleaning up after heavy rains from hurricane Irene which had leaked badly in my apt. I was exposed to something because I felt the effects immediately ( burning eyes, pain in ear, headaches, dizziness etc) I just found out I am allergic to Alternia (sp?)mold.
Have you asked your MD to do Mold allergen and dust mite testing? Do so just so that you know what you are dealing with.
Hot yoga is great,it is a little too intense for me but regular sessions in a sauna can work wonders- I am doing that to sweat out toxins.
If you know for a fact it was mold, go on a anticandida program (supplements and diet)since mold is a fungus and you have to get rid of it from your body.
