I had what I later learned was a systemic mold infection from people creating aerosolized particles out of an old swimming pool near my office. They were jackhammering the drained pool. They were wearing gas masks, I was not. Anyway, as a treatment I inhaled Colloidal Silver through a nebulizer on a regular basis and it was helpful. I also did hyperbaric oxygen treatments and improved nutrition, etc. Here is a site that talks about using Colloidal Silver through a nebulizer that seems useful.
I recommend staying away from Antibiotics as much as possible. The long term effects can include leaky gut and autoimmune disease. Colloidal Silver can be very effective against infection, and inhaling it is a good way to take it. If it works for you, you could sidestep the Antibiotics .
I have been trying to find for you another article I read that is about colloidal silver, but have not located it, so I'm sending this reply now. Will send you the other article if I find it.
I also recommend you look into Iodine - I did not know about it at the time, but knowing what I know now, I would have gone on the Iodine protocol. There is a curezone group on iodine.
