They could also end up taking away partial functions to what you were able to do before surgeries. Add to the risk of the surgery failing to achieve what it meant to do. This is why most doctors hold surgery as the last resort. Physical therapy is non invasive and in most minor to moderate cases are enough to fix or curb your symptoms in the long term. Of course you should make sure to go to a good one because a bad one can just make your problems worse if they do not properly diagnose your issues.
