Cervical myelopathy fusion

Hi I have an operation coming up at some time in the near future for cervical myelopathy, it was due to go ahead before the coronavirus outbreak but got cancelled, I’m having a cervical fusion in c5/6 I already have c3/4 fused already due to a neck defect I was born with, has anybody had the operation were it was caught early on? I’ve been told by my surgeon it’s best to operate when it’s been diagnosed early to stop the progression of the disease and they have found it quite early which is a plus but I’m still very unsure what to do because im obviously scared that I could be paralysed during the op and there are countless things that could go wrong, has anyone had the op we’re they are now having a good quality of life? I’m a 48 female and I don’t want to have years and years of pain and discomfort and op after op if at the moment my pain is bearable. I’ve already spoken to longsider (cliff) who has given me some great comfort and advice, but it’s good to hear other people’s perspectives on this, i would be great full for any responses to this. Thanks x
