Any answers might not be relevant. MRIs (or rather the underlying conditions in the spine) are like snowflakes -- no two are identical, and they can change. It's conceivable that two persons' MRI reports could be identical due to interpretation and language (even though the underlying conditions are not identical) yet their symptoms could be vastly different. E.g. it's not uncommon for some people with apparently severe degeneration to have very mild, or even no symptoms, while others with very minimal degeneration can experience varied and severe symptoms.

All that said, googling: degenerative disc disease cervical symptoms c6 should give you a pretty good idea of the range symptoms people may experience. Reviewing a chart of dermatomes may give an idea of where symptoms may be experienced, but charts of symptoms & location are a bit like the Pirates' Code -- they're "more what you'd call 'guidelines' than actual rules".
