In brief: Multiple things
If your left arm and leg are both weak, you can be having or have had a stroke.
Alternatively, brain tumors or seizures can lead to such weakness. Furthermore, high neck problems (discs, tumors, fractures) that are asymmetric to the left can cause these problems also. These are just a few causes by the way. See your md for a full workup.
