Waiting for results tests everyone. It’s human nature to imagine what we most fear. Every out of the ordinary symptom can be interpreted to mean ‘it’s back’! Except of course it doesn’t.
Having had cancer doesn’t make us immune to other things - infections of one sort or another, digestive upsets (intestinal
bacteria can cause pain), all sorts of stuff.
As far as possible, distract yourself - watch a funny movie, get friends around, go for a walk and let nature calm you. Remember, anxiety will change absolutely nothing and help absolutely nothing. I found I got much better in time, but it can take quite a while. Best wishes for a reassuring result.
