. I did post this in the 'Symptoms' section by mistake, hope this is ok to post it here again, because it is related to panic attacks I do believe, anyway, here goes - Hi all fellow sufferers. Panic attacks - yes I've had it all - first caused by vertigo brought on by (what a consultant decided was 'Menier's disease' 20 years ago. all cleared up now). But, over the years I have returned early from holidays', cancelled booked and paid for holidays the morning we were supposed to go, am unable to fly anywhere, can't travel by bus, it just goes on and on. And all this, and the reasons why it happens, has been explained to me over and over again by well informed people. I take daily medication for depression and blood pressure. I have a packet of Diazapan but only take it sparingly (had to twist my doc's arm a bit for that). but the one symptom that now causes me the most stress is this sudden sensation I get of losing all strength in arms and legs and end up flopping down on to the floor. It does not happen if I am controlling my day myself. But, if put in a situation where I must be somewhere, a particular place, at a particular time, bang - I make a visit to the toilet and suddenly lose all strength in arms and legs and have a need to collapse on to the bathroom floor. The feeling will only pass once I take back control and do only what I want to do, when I want to do it. Does any of that ring bells with anyone else, or am I some kind of freak? I do know that this is not related to 'low blood pressure'. I take my own blood pressure readings and it has always been fine when tested at these vital moments. And so, can anyone relate to this problem, I would be so grateful to hear of it, Anyone?
