Thank you for reaching out. We are happy to hear of your previous success with physical therapy!
Unfortunately, without doing an evaluation we can’t comment at length on your injury and exercise prescription, but we can discuss some general principles that hopefully answer your question and are helpful to you.
When rehabbing nerve related issues it’s common practice to avoid aggravating motions as the initial goal is to get the angry nerve(s) to calm down. Performing overhead exercises can be irritating to an already angry nerve as they are demanding tasks for the spine and shoulders. While this may have been your physical therapist’s thinking at the time, engaging in overhead motions and activities is an important part of rehabilitation as these are functional movements we encounter in everyday life; avoiding overhead motions altogether is not practical.
Furthermore, if you experienced this injury many years ago and have not had any symptoms since then, you can be confident that the initial injury has resolved. This, however, does not mean symptoms are not liable to re-occur.
We as physical therapists commonly encounter patients who develop movement patterns after an injury that compensate for a weakness or restriction that may have developed after the initial injury. In the short term these dysfunctional patterns may not present as painful, but when repeated over time they can lead to future injuries. For this reason we recommend consulting with a fitness professional before re-engaging with heavy overhead lifts.
Performing (light) free weight exercises below shoulder height, such as front and lateral raises, are good introductory exercises to start with before progressing to overhead lifts. When transitioning to overhead lifts, such as military press or incline bench press, be sure to start with a light weight to ensure both proper form and that they’re not aggravating in any way. Should you develop pain after starting a new fitness routine you should schedule an evaluation with a physical therapist to help identify and address any restrictions or dysfunctional movement patterns that may be occurring.
P.S. Pull-ups are considered an over-head exercise!
