Sharp pain in my left shoulder blade. neck pain radiates behind my ear. shoulder pain and soreness. and little arm soreness as well. pinched nerve?

Discuss with MD: You have a lot going on for your age, please discuss this with your doctor, you may warrant some further testing. This is not a good forum for this question as we can not diagnose "pinched nerve" without examination and testing. Your doctor may order a nerve conduction test coupled with an emg, or an MRI if they have not done so already. Discuss with your doctor.

Possible: Possible c3-4 nerve pinged. An emg/ncs study is indicated.
