Yes Gary I do have to travel.
I have arthritis in my neck,back,hips,knees,hands,wrists and feet so I do have to take a lot of medication for this and also hypermobility and hypersensitivity so i'm in pain day and night and it stops me sleeping,waking up at least 3-4 times a night.
I can't do ANY task repeatedly without pain,starting as soon as I get out of bed,is this actually what you mean when you say, 'so you need to ask yourself can I do this task repeatedly if the answer is no then you answer no if you cannot do anything asked of you then say so',i assume that means if they ask you to bend over,lift your arms and the like??
Sorry for being a twit but I must make absolutely sure

Very much appreciated.
