Your symptoms are unusual but there are some disorders that can cause these problems. I am uncertain why you have had two neurological consults without an EMG and NCV test (nerve function tests with needles(??) This is one of the first tests to consider with your symptoms.
There are three syndromes that can occur post-surgery that could be looked into. These are thoracic outlet syndrome, Parsonage Turner syndrome and Polymyalgia Rheumatica. I have written about two of those three topics on the website. You might also have chronic radiculopathy (on website also) but this condition typically occurs only on one side (unilaterally).
Please ask for some help with your depression with a health practitioner. Reactive depression is common with chronic pain and can be successfully treated.
