The pain has been in her arm for many years and in my opinion represents neuropathy.
Would I use a comma in this sentence or leave it as it is? What is the rule for comma usage in this type of sentence?
There is need to use a comma anywhere in this sentence. My rule is 'Don't use unnecessary commas' or 'Use commas only when they help in understanding.'
I'm not sure about 'represents', though. It's like saying 'My headache represents migraine'.
Perhaps Raymott (a medical practitioner) has an opinion.
