I have had arthroplasty’s done on both shoulders with the left one still as an anatomical. I have had for months pain anywhere from 6 to 9 on the pain scale. The pain is sometimes sharp, sometimes severe aching, and then the burning sensation. The area of pain is primarily the posterior area as well as the top of the shoulder, and front-side. Now the left shoulder is the real problem, and it also has a tear in the subscapularis, supraspinatus, and atrophy in the teres minor. I have some weakness, definite stiffness, and poor range of motion due to the pain. If I have a severe compression at C5-C6 posterior left, and the rotator cuff tears, will the compression of C5-C6 be attributable to the majority of the pain or is it the tears in the rotator cuff? I do get some tingling/numbness in the left thumb and forefinger and a bit of sleepy like sensation in the entire hand. But the pain in the shoulder region is at times unbearable. Your thoughts would be very kind and appreciated right now for me.
To differentiate pain generators from neck vs. shoulder, diagnostic injections should be used. If a shoulder injection relieves your pain, most likely the pain is shoulder in origin. If a selective nerve root block of the 1-2 roots yields relief, then most likely the neck is the source.
