Hello,

We need a physical examination and assessment of the upper limbs. As you mentioned about having weakness in the arm and unable to lift, I feel this should be related to the nerve impingement. As nerve has a function of motor and sensory any disturbance in the nerve functioning can lead to such symptom. As it is occurring only in the lying position I think this should be due to pressure falling over the nerve in the cervical region leading to dysfunction of the nerve and leading to symptoms.

Please do some neck stabilizing exercises for which you can find videos online about cervical spondylitis.

Most cases in my 12 years of experience have recovered well with simple exercises.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
