I am sure this has been written about before but I am having a particularly bad day with these shaking vibrations. It is only behind my chest and sometimes runs down into my abdomen area. It feels like I have about 50 cell phones inside me that are vibrating. I am wondering if anyone knows what this is and the cause. I haven't done anything different the past few days...no added stress etc. Its not even that I am tired...sleepy or fatigued. I just feel kind of empty and drained inside. I have no idea why this is suddenly going on today. I have had this in the past and there just doesn't seem to be a pattern or reason behind them. I suppose there probably isn't any reasoning where this illness is concerned. I did wake up feeling kind of drained this morning for some reason so maybe this inner vibration is the result of that. Nothing helps this feeling...I have tried klonopin...Ativan...L theanine...kavanace...and it doesn't calm them down. This is one of my worse symptoms when it happens as they are just horrendous.
