Glad to have helped SamP. I made myself very ill with worry about this particular symptom at the beginning so I can totally understand how distressing it is for you.
I also suffered health-related anxiety about lots of other things for many many years and understand too the vicious cycle of noticing a body sensation, worrying about it, noticing it more, worrying about it more and on and on it goes. I am more aware of my own reassurance- seeking behaviours now which as I understand it from current theory only fuel anxiety rather than dampen it. Nowadays I have to be very strict with myself (in a kind way of course!). If I have a health concern I deal with it once (getting it checked by gp or whatever is required) and then, when I get the all clear or have it dealt with, I stop.
Every time I’m tempted to look it up online or make an appointment with the gp or ask a friend for reassurance or whatever, I do something else to distract myself. It isn’t at all easy but eventually the urge for reassurance fades. I even find forums like this one, although they can be really helpful and reassuring, can allow the worry spiral to continue for me, so I have to be strict with myself about how I use them.
SamP I really feel for you and I wish you all the very best in your efforts to accept your symptom and stop your mind wandering. Be kind to yourself and I’m sure you will get there and have some relief from the awful worrying…
