I had a bad mold problem in the crawl space of a house I bought in 1999. After 5 years in 2004 I started to develop symptoms. We didn't know the house had mold much less that mold could cause a lot of neurological problems. My first problem was I awoke with anxiety attacks in the middle of the night. Later I developed fasciculations in my lower extremity muscles which then moved into trunk and arms. Then I developed severe spasms in my lower legs with my ankles and feet especially when I was laying down. Then I started having events of SVTs that where quite disturbing. I will not bother with all the other symptoms. For 2 1/2 years, after first seeing a neurologist who was clueless I was treated for Lyme disease by "Lyme Literate" doctors who were also clueless. I found my way to an MD who was at the forefront of developing testing and treatment for mold and within 6 months I was mostly recovered. The one symptom that took the longest to recover was multiple chemical sensitivity. MCS acted up when I would smell a chemical which could be anything from perfume to soap or paint or newly paved asphalt and on and on. That took a couple of years to recover. MCS also made me sensitive to drugs.
