Lung CT tomorrow, then the horrible wait

On 4th October it will be a year since finishing active treatment. During chemo my voice changed around day 4 each cycle and felt weak. Not long after finishing rads I developed an irritation in my throat/oesophagus region and I also developed a cough. The irritation is worse after eating and when I breath in deeply. My GP prescribed Pariot to treat reflux for oesophagitis. I have been taking Pariot for about three months but haven’t experienced any improvement. I had my six month onc review last Tuesday where I discussed my symptoms and concerns. She basically dismissed the possibility of it being oesophageal Mets, but I’m still stressed about it. I have nerve damage inside my ears which she described as unusual but because of that she thinks I may have nerve damage to my voice box. However she did think it was reasonable to do a lung CT because of my cough. It’s the night before the scan and of course I’m starting to stress. I have tried to keep busy and not think about it but I just feel like I’m finally getting back on track. Has anyone else experienced side effects in throat/oesophagus after chemo? Any advise would be greatly appreciated.  Thanks, Sophie.
