Persistent left arm pain and numbness; barely relieved by nsaids; involved shoulder to hand; flares up while sleeping; no structural cervical damage or injury presented. Ongoing for 3wks. Sometimes shoulder is involved with the pain. No hx of heart issues.
Dear patient your symptoms indicate diagnosis of cervical canal stenosis reason may be disc prolapse. Disc herniation in cervical area leads to compression on upper limb nerves and tingling numbness in upper limb. Confirmation can be done by MRI of cervical spine. Get it done from radiology center nearby you. Meanwhile, start tab regain x 75 mg one at bedtime. Use soft pillow at night.  If MRI is abnormal you need to consult neurosurgeon as soon as possible. Thanks.
