hi all good to be here i have already learnt so much my problems are quite minuscular compared to most here but are certainly wearisome. I am a 21yo bodybuilder who 18 months ago began to suffer from chronic pain in the left side of my upper back. In a short amount of time my left latissimus dorsi had atrophied to half the size of my right. After having an EMG/NCV scan the problem was diagnosed as an isolated thoracodorsal nerve dysfunction that is chronic in nature. I have not yet learned the cause of the injury, which leaves me wondering if when i eventually return to training the problem will return again. My Sport Physician advised that with a limited workload in the gym and avoiding overly stressing the lats that the nerve should have reinervated after 18 monthes. Those 18 months have now passed and i still have a muscle imbalance between the lats and mild pain in the left lat and left thoracic area. After being unable to train the back my strength has diminished and my posture seems to have worsened slightly. My left shoulder noticeably hangs forward and is uncomfortable to pull back and down into correct posture. In the last 6 months i have also had some sciatica like pain and inability to "feel" the muscle contract in my left hamstring and calf. I haven’t exercised in months in fear of further injuring myself. I have no pain or injury to the right side of my body. I am seeing my sports dr again next week and will ask for another scan to check the nerve but i am sure there is an underlying issue. I am unsure of my next course of action and would appreciate any advice.
