Hi Neil mate,
Yeah Im now going for walks, but also stopping the checking of the pulse has really improved me.
Mind you its only been a week & I still find myself listening to my body.
Im trying to accept that your body has sensations etc... so we'll see how it goes.
If your pulse is normally between 50-70bpm, thats very healthy if you ask me.
Usually mine would be between 67 & 80bpm. When im very relaxed, maybe around 60bpm. Either way Im sure yours is stress related & if you can somehow stop listening to your body....very hard at 1st, you will see a noticable reduction in the symptoms.
Let us know how you get on with those tests matey.
Pete
