I started internal vibrations/tremors 4 months ago. I thought they were better but we’re not...until, I found what appears to be the reason behind the vibrations. I had a roof leak in June 2019 it was found. The hoa contractor plastered over two wall sections that showed water damage. One wall section was very large 7’ tall x 31” wide. He did repair the mold he found in the ceiling. I kept being very sick. Unusually so. I had a contractor come open the wall. He found very bad mold. I did the mold analysis test. Just got result. It was chaetomium. A dangerous mold that can permanently damage your nervous system. I have been staying in my daughters room, unfortunately she got the sofa because I’m disabled and have pain. I get the mildest vibrations now but only when I go near the water damaged area. It’s been an answer!!! And it’s been consistent. I sleep all night no vibrations and they used to be the worst at night. And I have just the super mild ones when I get even close to the fireplace. The rain leak was at the chimney. Unfortunately it’s not my liability and I can’t afford the repair. So I’m trying to work with the HOA in hopes neither of us have to spend money on an attorney. I will pray for you, if that’s ok. I don’t get on here often I’m visually impaired. But would ask you to consider if there has been any leak even in the past in the home you live in. Mold is coming out from my research to be a cause of things like Alzheimer’s. I saw they are going to put something out and it’s important info. I’m only good at research. I don’t claim it’s 100%. But might be important for you to did deep into research on the web about chaetomium and mold causing nervous system damage. I hope you improve. I know what you feel. Super scary all day long having those vibrations.
