You do have a disc herniation according to the report at T5-6 but this will not cause arm or neck symptoms.
You have a small central disc herniation at C6-7 but it is not compressing any neurological structure (“A small posterior central 6/7 disc protrusion is seen without associated neural compromise”).
Neck pain and shoulder pain can be generated by degenerative discs without nerve compression but numbness and paresthesias are generally nerve compression generated. You can have multiple areas where nerves can be compressed in the shoulder and arm. See “Nerve entrapment and compression” on the website.
