MRI findings are important but need to be compared to your symptoms and physical examination findings. All the symptoms you note are “Weakness of grip and strength bilateral arm”.
I can tell you what symptoms you could have based upon the MRI findings. You have no real central cervical stenosis per the radiologist so myelopathy should not be present (see website for description). The most significant findings you have are moderate to severe foraminal stenosis on the left of C5-6 and C6-7.
This would cause left arm pain and paresthesias (pins and needles) that radiate down to the thumb and fingers on the thumb side of the hand. You might have a weak left triceps and biceps muscle. You might have problems with strong grip in your left hand. Bending your head backwards (extension) could cause the pins, needles and pain to increase down your left arm.
